Finance and the Treachery within

Of all the Industries, the one that is loathed despite its laudable achievements is the world of finance. If not for the inventions in finance, most of us would still be bartering stuff around and hoping that you have what I need and you need what I have.

While inventions in other industries are lauded, in the world of finance, invention in recent years has made one wonder as to whose good these instruments of finance really are.

At its simplest level, finance is all about money changing hands from one who has more than he wants (for now) to one who wants more than he has (for now). Every business is build on its ability to finance its investment from one source or the other.

Directly or Indirectly, most of us are participants of every nature of business there is. While investing in Equities or Bonds is a direct way, when you lend your money to the bank and they lend  to a business, its a indirect way wherein your money is channeled to the business with the risk being spread across.

Mutual funds are one way of participating in the business with the main logic being that the fund manager knows better than others. But does he really know any better?

Every month, reports go out on what funds bought and sold and the list is large enough to wonder as to why fund managers need to trade so much even as they hold in disdain any form of short term trading / investing. HDFC Equity Fund for example (picked up at Random) has a turnover ratio of 34% which means that the whole portfolio is literally turned over every 3 years and yet, we have fund managers who shout from the roof tops the advantages of holding for the very long term.

Since 2000 if not earlier, there has been reports of how monkey’s have been able to beat professional money managers (at least the vast majority of them). While there is no monkey out there with ability to pick the best stocks, the reason behind their success lies in the fact that markets being random, everyone has a chance at hitting the jackpot once in a while.

Some time back, the book 100 to 1 in the Stock Market: A Distinguished Security Analyst Tells How to Make More of Your Investment Opportunities by Thomas William Phelps started to make waves in the financial circles. I myself have not been able to read it though thanks to the world of Blogs, was able to get detailed reviews of it.

The thing is that no one, not me, not you, not the hot fund manager right now or the wise wizard next door has a clue about which business will click and provide tremendous gains over the next 10 / 20 / 30 years and which won’t. This means that one really cannot buy a few selective number of stocks and hope for the best.

In fact, right from Warren Buffet to the value investor down the road prefer to reduce risk of the portfolio by diversifying the same. Mutual fund advisers advise one to invest into not just 1 fund but 4 – 5 funds to reap the benefits. But if you were to total up the stocks, you may very well find that you own nearly 70 – 80% of market capitalization ranked stocks.

Much of the financial world is made of monkey’s who offer to provide the service of sharing their cake. As you would know the story by now, its the monkey who stood to gain from the cat’s misfortune. There is literature after literature, all backed by data going back decades and even centuries about investing in a simple index fund being way better than in any mutual fund. But we are told that India is different and Indian fund managers are really able to generate Alpha – something that even Warren Buffet is finding difficult to achieve these days.

The solution to every problem and goal you have in mind is now easily achievable by doing a Systematic Investment Plan we are told. No amount of words or data seems to change the beliefs of the non believers, so let me try and tackle the issue in another way.

What are the Primary reasons for Investors to invest using SIP. Based on my discussions, I could come up with the following

  1. Unlike in the past, we are told that youngsters these days don’t save much even as they draw mouth watering salaries. Unless some part is taken off and invested, they may not have much by the time retirement comes calling. Also since they are butter fingered when it comes to money, they cannot accumulate money to buy when markets are cheap.
  2. Most investors have no clue about investing and aren’t prepared to make efforts to learn the same. Hence investing directly in stocks is too risky for them since they cannot understand the difference between say a Jet Airways and a Kingfisher.
  3. By investing every month regardless of valuation (which they cannot perceive anyway), they can hope to benefit by long term averaging (in fact, the other word for SIP is Dollar Cost Averaging).

So, any alternative to Systematic Investing has to be one where no grey matter is strained and its simple enough for execution.

One of the ways to generate wealth on the stock markets is to buy Good companies and hope that they continue to grow for decades to come. Easier said than done as evidence has shown that even companies that are part of Indices can come to naught.

Buying the blue-chip of today may provide you with a decent return but nothing extraordinary while if you can buy a stock before market start to believe in it, you may have a real wealth generator out there. Its similar to investing say in Kohli before he started notching up his Centuries. His price (even say in case of Sponsorship) would have been way lower than what after market recognized his abilities.

But identifying such companies is not easy – not even for fund managers who prefer to buy the safe stock than risk (and rightly so) on companies that may emerge to be the next big thing. Most mutual fund portfolio’s are hence full of stocks that are similar in nature (and hence more the funds, more the over lapping).

What if instead of putting X amount of money per month into a scheme you invested the same into a random stock. A stock that was chosen by anything but skill, how do you think that would play out?

Well, I tested out the same. Using a survivor free database, I selected stocks every month randomly and assumed to have bought the stock for the money I was investing (10K per month). Every month all I did was throw a dart and buy the stock it picked.

The negative of the strategies would be

  1. You will have a lot of bad apples. After all, not every company will thrive on the long run.
  2. Your demat statement will run into pages after a few years as you keep adding more and more companies over time.

The positives of the strategy are

  1. Since you invest only a small sum every month, the maximum risk would be losing one month of investment. On the other hand, if you can over time get even a single 100 bagger, it would ensure that 99 other bad apples are taken care of
  2. Cost is small for executing this strategy. These days with brokerage firms offering Zero brokerage for Cash Delivery, the net cost would be way smaller than any other comparable investment (even Vanguard is beaten).

So, how did my test turn out?

I selected 120 stocks from Jan – 2005 to Dec 2014 and invested 10,000 into them. I did not add for Dividends which over time can turn out to be a good enough amount and one that will take care of the costs (Demat / Exchange costs) and more.

So, how did it turn out? A 10K investment per month for 120 months meant a principal investment of 12,00,000. At the closing prices of Friday, the current sum would have been 74,13,875.35 and since the investment was monthly, our XIRR return comes to 29.40%.

Of course, this is just one streak of many (given the randomness) and you may actually end up either better or worse than the above number. The intention of this post is to provide you a view on how you can build a large kitty without having to wonder if you have picked up the right fund manager and if the fund manager is making the right bets.

Much of the finance industry is about making grandiose statement without providing the data to back them up. They say that if you SIP for say 10 years, you returns would be great, but is there is no possibility of having a loss after 10 years? Not even 1%, Zilch? Really??

Hundreds of thousands of Crores change hands from investors to those with the ability to market themselves as being the savior of your savings with no one being the wiser. As a adage goes, “The fool and his money are soon parted”.

When the financial crisis hit in 2007 / 08. thousands of investors lost money, many bankrupted. As to those who sold them such products in the first place? Well, most of them are well off and many are in a better position than during those turbulent times.

As I repeatedly emphasize, every one is after you money and its up-to you to safeguard the same. If you fail, you cannot have anyone to blame but yourself.

 

 

 

 

Cigarette and Investment

Today, by a sudden hunch I wanted to know what if some one who smokes had invested a equal amount of money into the shares of the leading tobacco company (ITC). How would the Investment fare and what would be the current value.

And before I say anything, let me say that I neither smoke nor have invested into ITC shares, so no point sending me the joke below 🙂

Lady: Do you smoke?
Guy: Yes I do.
Lady: How many packs a day?
Guy: 3 packs.
Lady: How much per pack?
Guy: $10.00 per pack.
Lady: And how long have you been smoking?
Guy: 15 years
Lady: So 1 pack is $10.00 and you have been smoking 3 packs a day which puts your spending per month at $900. In 1 year, it would have been $10,800. Correct?
Guy: Correct.
Lady: If 1 year you spend $10,800, not accounting for inflation, the past 15 years puts your spending total at $162,000. Correct?
Guy: Correct.
Lady: Do you know if you hadn’t smoke, that money could have been put in a step-up interest savings account and after accounting for compound interest for the past 15 years, you could have by now bought a Ferrari?
Guy: Oh. Do you smoke?
Lady: No.
Guy: Then where’s your fucking Ferrari?

Of course, there are several caveats in such a study. For instance, there are smokers who smoke a stick or two a day and then there are those who smoke 2 or even 3 packs a day. To be conservative, I took a smoker who smoked around 5 cigarette a day and did not smoke on week ends. That comes to a neat 10 packs per month.

I tried searching for data on what ITC charged per cigarette over the years but could not find any such statistic. Good friend Kora Reddy came to my aid with the starting number (1995). Since I know the current price, I just incremented the price over the years (CAGR of around 12.5%). This is clearly not the true price, but definitely something that could be used for the test.

ITC has over the years given Bonus as also split the face value of the stock. Since that would complicate things too much, I used adjusted data (adjusted for Splits / Bonus but not for Dividends). In 1995, ITC was traded physically and getting odd lot shares may have been tough. And prices would definitely not be the one I used (post split), but, once again, idea is to get a rough number than a very accurate one.

The concept was simple. When you buy say 10 packs for the month, you also buy shares for the same amount. So, in affect, every time one smokes a pack of cigarette, the amount that gets debited is more or less equal to 2 packs.

Starting from 1995 till end of 2014, I assumed a person would have smoked around 2400 packs (10 per month * 12 months * 20 years). The total amount spent on that comes to around 82,500.

If the same amount was invested in ITC shares, he would have bought approximately 1316 shares. If one uses the last investment price (Dec 1, 2014), the value of his portfolio comes to around 4.79 Lakhs. Since the investment is staggered over such a long period, using XIRR, I get a return of 19.97%. That is actually better than Gold or Nifty. Food for thought, eh?

So, the next time you buy a pack or carton of cigarette’s do think about calling your stock broker as well. Who knows, you may actually end up a millionaire due to your bad habit.

Taking advise from Strangers

There is a wonderful quote from the Oracle of Omaha wherein he says 

Wall Street is the only place that people ride to in a Rolls Royce to get advice from those who take the subway.

Its amazing how true that statement is in the financial field while not being true in any other profession. For example, the other day, a friend complained about pain in the ear. My initial thought on that subject was that the probable cause was it being a infection and the remedy would be a cheap anti-septic ear drop. But my friend decided that he was better off consulting a specialist (and I do agree with that 100%) since I am no doctor to advise and we all have heard about how dangerous self medication can be.

If a light bulb burns out, generally some one in the house easily replaces it but if a switch got burnt or broke, more time than usual, a electrician is called in to change the switch despite the job being no risky than changing the electric bulb. The reason is simple – the probability of getting a electric shock if you are dealing with a open wire is much higher than one that can be caused when changing a bulb. 

But when it comes to advise in the markets, its amazing how all and sundry can make an impact and how easily we fall prey to such advise. One reason for that I believe is that the pain that is caused by financial loss has a much lower impact than one caused by say a electric shock. If you try to do some thing and get a electric shock, the probability of you trying to do the same thing once again is much lower compared to doing the same thing in markets where we just tell ourselves a new story as to why the previous tip based trade failed and why the current should / shall work.

Statistics tell us that the probability of a failure for a trader is pretty high, yet that seems to make one more deterministic about how we are better than those other failures and why shall win this time around. Having been a full time active participant in the markets for more than a decade and a half, the one reason I can see for that is the fact that many are successful in their own fields and wonder why cannot they be here where the odds seems reasonably low in comparison.

For instance, to be a professional in any field, one needs to study and excel for at least 5 years while to be even worthwhile to enter the said field while to be a trader / investor, all one needs is a PC. Most have little knowledge about the company or even the methods they claim to follow. Have talked to many traders who claim to use technical analysis but cannot distinguish between RS and RSI let alone explain how they are constructed.

Of the guys who I have seen as having succeeded in markets, the one thing that has been common among all of them have been their devotion in terms of time and energy. All of them are full time traders / investors whose bread and butter is from their trading / investing activity and not Salary / Brokerage / Business or the trading being a part activity after retiring from full time service elsewhere. This in a way compels them to be either successful or find another profession (and as elsewhere, Survivorship bias does have its way even here with many who did devote full time too failing).

The reason for advisory services to have a field day in the stock markets as compared to elsewhere is that a lot of times, you just have to be lucky to be right and if markets are on a one way trip, it makes it even better if the markets are trending since then the odds of the stocks moving in favor of the trend remains high.

Of course, picking a few odd stocks cannot be a way to build wealth, but then again, who cares since the brain has this innate ability to think positive and multiply one good trade due to luck into a series of good trades. As Benjamin Graham said and I quote

In the short term, the stock market behaves like a voting machine, but in the long term it acts like a weighing machine 

Luck can be of help in the short term, but over the long term, skill outclasses luck (think about the 10,000 hour rule made famous by Malcolm Gladwell. You can make some money i the short term by paying for tips / newsletters and seeing some of them succeed as well, but if you really want to succeed in the long run, the key requirement is that you are hungry for it and make it  your business to know anything and everything there is to know about a business. 

Maggi on the Wall – the bigger picture

In my last post titled “Throwing Spaghetti Against The Wall” I showed how after picking up 3 portfolios whose stocks were randomly picked, I could still beat the overall return of the market over a time frame of 10 years.

In continuation of the same, I decided to to a double blind test on picking random portfolios and comparing them to the returns Index gave. I randomly selected 1 date in a year and on that date randomly selected 25 stocks (all done through Excel so as to avoid any bias creeping in).

I did it for the years through 2005 to 2010. The results can be downloaded from here (Link). To summarize the same, Random portfolio created beat the Indices in 3 out of the 5 years, in 1 year it under-performed Nifty and Mid-cap while out-performing Small cap Index and in one year has under-performed all other indices.

But if one were to take the final tally, the net results beat the results of all three indices comfortably.

The question that comes thus is, is it a real waste to spend time, energy and money trying to analyze companies? Well, to me, it isn’t so if you believe that you are the 5% of the achievers when the rest of the 95% under-achieve. But if you aren’t sure and your bank balance (from trading / investing and not Salary / other Income) doesn’t seem to show that, its not too late to admit and get back to doing what we do best.

Do note that the only filter I have used was to select stocks that had closed the previous day above 50. It did not matter for me whether they were bullish / bearish based on technical parameters or whether they were fundamentally strong or not based on value analysis. Its pure random selection.

The reason why its tough to believe and even tough to implement this in real life is that we are all suckers for stories. We want a solid reasoning (that resonates with our mind) that comforts us that despite the fact that our investment is deep under water, its not we who are to blame but market forces and the desertion of lady luck.

The whole financial industry is build on this story that you can be better than the markets though not everyone can be above the average (statistically impossible, eh? ), the story has takers (as can be evinced from the number of Mutual funds to PMS to Hedge Funds who offer to take care of your money for a small fee). 

In US, it seems for the first time in decades (if not more), people are finally getting out of active strategies and investing into passive ones (ETF’s that provide market returns with minimum fuss and very low charges). Here in India we do lack the spread of ETF’s that are available in US, but I believe that over time, we should see more and more ETF’s hit the market and that would enable investors to invest without having to pay through the nose and yet end up with more or less the same return (or heck even lower).

The reason random portfolio works has nothing to do with selection (after all, we aren’t selecting) but with the concept of compounding. If you were to look at the excel sheet, you shall notice that its not the number of winners that count, but the returns outliers have been able to deliver. 

For example, in the portfolio of 2009, the biggest winner was Vakrangee Software. This one stock was able to return the whole capital in affect making the other 24 stocks free. 

Warren Buffet has made his money not because he was able to pick all the right stocks, but because some of the stocks he has picked has been multi-baggers to a extent that it wipes off the losses of the few stocks (or should I call business since he having grown so big rarely picks up small stakes and instead wants to get fully into the company) where he called it wrong (and he has several wrong calls).

Markets grow in fits and starts, but in the long term, growth is there for sure (unless you believe that the India story is done with and we shall see a phase such as one seen by Japan). Long term some business will grow at a pace more than others and if we are lucky to have them in our portfolio, our returns should at the very least equate to market returns and at best out-perform the other asset classes easily. And all this without having to burn mid-night oil on what stock to buy, when to buy, when to sell and a thousand other loaded questions.

And before I conclude, do read about how funds rated as Gold can under-perform and many rated neutral / negative outperform (Link). If companies that spent thousands of man hours analyzing in depth funds cannot distinguish the bad apple from the good, what are the chances we can?

 

Throwing Spaghetti Against The Wall

This post has been driven by a deep discussion I had with Nooresh Merani today and hence the credit for the idea would remain with him 🙂

While study after study has shown that retail investors are unable to match the performance of the Index let alone beat it, it has not stopped a army of advisors and technocrats from coming up with new ideas, ways and thoughts on how to select stocks and become retire rich. 

There is a very famous quote by legendary trader Jesse Livermore which goes as such 

“It never was my thinking that made the big money for me. It always was my sitting. Got that? My sitting tight!”

Sitting tight is the easy thing to do when you have no real money at risk, but once you have put money, can we sit tight and hope while the stocks we have bought are moving all around. I am jumping the first step, so let me go back.

How do we create a portfolio?

A portfolio is a set of stocks we buy that we hope shall perform in the long run. But since we are provided both a price and a opportunity to trade the stocks day in and day out, its just a matter of time before we let go all the wonderful stocks we had picked (by way of Luck or Skill) while adding or at the least holding onto stocks that are touching the nadir. 

The discussion I had with Nooresh was about whether a Random portfolio (contructed purely out of chance) can beat Index returns if one just invested and sat tight. 

While we hope that every stock we buy ends up being a multi-bagger in the long run, its very rare for us to not just buy a few stocks that eventually end as multi baggers but actually hold them.

The test I did was simple. I took a 10 year time frame (long enough I presume for a long term investor). I used April 1, 2004 as the starting date. The date had the additional advantage of markets being near a short term top (in hind-sight) since after NDA lost the elections, markets took a steep dive and hence for at the very least 6 months from entry, we were underwater.

The biggest problem in conducting these types of tests is that finding historical data is tough since delisted / merged stocks are moved trimming the database of that day considerably. Since I maintain a database where delisted stocks aren’t deleted, it made it a bit easy for me to work on the approach I had decided upon.

I took the Bhavcopy of NSE of 1st April 2004. On that day, 750 stocks were traded and I removed 250 using the filter of removing any stock that had closed below 25 on the previous day (Idea is to remove penny stocks).

I then used Random function in Excel to randomize the 500 that remained. I then selected 3 sets of 25 stocks each from them (1 set each before refreshing and randomizing the set of names again – and hence a couple of stocks do repeat).

I then used the Opening prices of these stocks as per my database (where its adjusted for Bonus / Splits but not for Dividends) so as to get the current average price of acquisition. All acquisitions were assumed to be equally weighted (same money invested in each stock)

So, how did the three perform compared to Nifty. Well, here you go

Image

Every Random Portfolio beat the CNX Nifty. Is it Luck? Maybe to an extent, but what drives a diversified portfolio is if you can get caught with a few multibaggers. Regarless of how badly a few others do, since the exposure to each stock is 4%, not much of damage can happen while the ones that click big shall make more than what they lost (worse case, you lose 100% in a stock. If one stock moves 400%, it makes up for the loss of 3 of them).

I am not suggesting that you need to buy stocks randomly, buying good stocks is said to make a lot of money, but unfortunately we come to know of good stocks only after they have bolted off the stable (hindsight).

Food for thought?

Distribution of Stock Prices across Exchanges

BSE being a pretty older exchange (in fact, its the oldest exchange in whole of Asia) has the distinction of having the highest number of listed securities compared to NSE. But as we all know, Quantity doesn’t have to mean Quality. 

On most days, we see around 3000 stocks getting traded on BSE vs 1300 on NSE. The average price of a BSE ticker comes to around 160 vs. 260 on NSE. 

Below here is a distribution pattern of the % of tickers that are priced at specific prices (do note that since all stocks do not trade on all days, there is a number of stocks that would miss depending on the date of test).

Image

I am always suspicious of penny stocks. Its hence interesting to see that BSE dominates the number of stocks which trade below 25 and above 25, NSE seems to rule the roost. A lot of stocks are listed both on NSE and BSE and hence there will be a significant overlap.
