One Basic Lesson in Investing from the Tata-Mistry Spat

Nov 1, 2016


Many media reports have been published around the spat that is currently on between Cyrus Mistry and the Tata Group. Mistry, till he was fired by the board, was the Chairman of the Tata Group of companies.

A report that has made it into the media over and over again, is that of the market capitalisation of the Tata Group of companies, falling by so many thousand crore, after Mistry was fired. Here are the links to a few of these reports.

What is common to all these newsreports? They talk in absolute terms i.e., the market capitalisation fell by so many thousand crore. They don't talk about the fall in market capitalisation in percentage terms.

This is a huge mistake. Allow me to explain. Let's say the market capitalisation of a stock was Rs. 100 crore. It has fallen by Rs. 20 crore and is now quoting at Rs. 80 crore. Let's say the market capitalisation of another stock has also fallen by Rs. 20 crore is now quoting at Rs. 980 crore against the Rs. 1,000 crore earlier.

If we were to follow the formula of the Indian media, we would say that the total fall in market capitalisation of the two stocks has been Rs. 40 crore. But that means nothing, given that the fall in market capitalisation in the first case has been 20 per cent and in the second case has been 2 per cent. By adding the losses, we take this nuance out of the equation. It is important to remember that a fall in the market capitalisation of a stock is always with respect to the market capitalisation prevailing earlier.

Now let's pay attention on one particular media report here, which said that the total fall in market capitalisation of the Tata Group of Companies between October 24, 2016 and October 27, 2016, was Rs 55,000 crore. Take a look at the following table. It lists out the the fall in market capitalisation of the Tata companies for the period under consideration.

This table was shared by a senior editor of the Mint newspaper on Twitter. (I have changed it slightly to the extent of rounding off the numbers). The text accompanying the table stated: "#TataSons meltdown Conglomerate loses Rs. 55,000 crore in market cap in 3 days as #CyrusMistry ouster snowballs."

The market capitalisation of the Tata companies fell by Rs. 54,765 crore between October 24,2016 and October 27, 2016. This has been rounded off to Rs. 55,000 crore. While Rs. 55,000 crore sounds like a huge number, it doesn't really mean much in this case.

If we were to look at the situation in percentage terms, then the total market capitalisation of the Tata companies fell by 6.5 per cent, over the three-day period. While, this is huge, it doesn't sound as big as saying that the market capitalisation has fallen by Rs. 55,000 crore. This is what the media has been doing.

Further, if one were to look at the table carefully, it is easy to see that the bulk of the fall in market capitalisation is because of one company and that is Tata Motors. Of the total fall in market capitalisation of Rs. 55,000 crore, Tata Motors is responsible for a fall of close to Rs. 32,000 crore or 58.2 per cent of the total fall.

How does the situation look once we adjust for this anomaly? Suddenly the total fall in market capitalisation is down to around Rs. 23,000 crore (or Rs. 22,747crore to be precise). In percentage terms this fall is around 3.4 per cent.

Now the situation doesn't look as bad as it did earlier. Or to put it in other terms, if Tata Motors, is taken out of the equation, the media headlines are no longer as sexy (for the lack of a better term) as they originally sounded.

The point being that one Tata group stock i.e., Tata Motors has had to bear the brunt of the spat between the Tata Group and Cyrus Mistry. In fact, between October 24, 2016 and October 27, 2016, the price of the stock fell by 17.8 per cent.

The other big fall has been in the case of Indian Hotels. The market capitalisation of the stock fell by 15.2 per cent between October 24, 2016 and October 27, 2016. If we were to leave this stock out as well, the total fall in market capitalisation of the Tata Group of companies comes down to 3.2 per cent.

The investors in these cases perhaps did not like these stocks anyway, and were looking for an excuse to sell out of them. The Tata Group and Cyrus Mistry spat, just provided them an excuse for it.

The major point here is that we all like to look at absolute numbers. But that doesn't really mean anything unless we take percentages into account. This is because a rise or a fall is essentially meaningless without taking the previous price or market capitalisation into account.

This is a tendency to concentrate on absolute numbers is visible in real estate investing as well. People tend to fondly remember anecdotal stories about friends, relatives, neighbours and others, who bought a flat for Rs. 10 lakh and sold it for Rs. 60 lakh. They do not factor in the expenses over the years or the time value of money.

And that is one of the reasons that has kept the real estate bubble going.

What is the stupid way of analysing the thing. Why do you want exclude the Tata motor & Indian Hotel. They are not Tata company?
Why not exclude TCS from this & work out the market cap. It will be big % drop.
I fact if you exclude the TCS,the performances of the group company will be worst than PSU(whom you criticize day in day out)

To: Mr. Vivek Kaul

Your article states that between 24th and 27th October 2016, the market cap of Tata Motors fell by 17.8%. But the stock price data indicates that the fall was much lower. Going by the closing prices of Tata Motors equity shares and Tata Motors DVR on the respective dates, the magnitude of loss appears much, much lower:

Tata Motors equity - On 24th October, Rs.559.10 ; on 27th October, Rs.521.85 = fall of 6.7%

Tata Motors DVR - On 24th October, Rs.363.30 ; On 27th October - Rs.338.80 = fall of 6.8%

Above figures indicate a fall of only 6.7-6.8% in market cap of Tata Motors. I am not aware of any other equity instrument of Tata Motors.

I will appreciate receiving your reply with clarification on the rationale behind your assertion of 17.8% market cap.

Outstanding analysis in common-man's language. Issue is not whether one is a investor or is governed by the advice. Important thing is that a person who is not an Investor( person like me aged 79 years) still wants to understand the full impact on Market Capitalization of the crisis. I really appreciate it and thank Vivek.

It's like the story of a child being asked if he wanted Rs. 100/- a day for a month or, Re. 1/- on day one and a doubling every day. Ask people what 2/4 is in terms of percentages and they will wonder. Post graduate college students, when asked what was half of one sixth, almost unanimously answered, one third. A solicitor, when asked how far 900 metres was, thought it to be across the road. He was shocked when it was marked out to him in terms of landmarks.

Reporters are to be blamed too. A hundred thousand crores is so much more salivary than say, 12.7 %; as you rightly mentioned. Moreover, many of them, including TV channels are phoning us for comments on the future of the Tata group. Just because we are Parsis. As if we are all knowing. In spite of, I believe, Cyrus being not a full Parsi; and an Irish citizen to boot.By the way, Tata Steel, the "Parsi widows'" share, is doing extremely well for the last six months, ever since the first CyTan rumblings began. Noticed it? 65% up. So, what's a little set back in times of universal south bound markets? Relax.

And no. I am not an expert on either the stock market or the Tata business. And I hold no shares anywhere. I just love economics and the yet to be propounded 'Theory of General Moods and Human Reactions'.
