Discounted Cash Flow Assumptions


Let me preface this note by stating emphatically that I am an economics novice.  But I’m going to take a stab at this problem because it’s crucial for the individual investor.  Please let me know if I’ve made glaring errors in the facts.

The theoretical definition for intrinsic value = present value of all future cash flows.

For this we need the amount and timing of all future cash flows, and the long-term risk-free interest rate.

We can assume the long-term risk-free interest rate to be the rate on 10-year Indian government bonds since they’re free from risk of default (the government just needs to turn on the printing press) and the 10-year are reasonably well-traded implying a closer approximation to the actual cost of money.

This rate stands at about 8.3% (27th June, 2011) and can be plugged in our present value calculations.

But the other two variables – amount and timing of future cash flows are the difficult items.

So, how can we, as individual investors get a handle on it?

Obviously this will vary from business to business but what reasonable estimates can we make about the general expected growth rates of cash flows for the typical profitable Indian company over the next 10 years.

I would argue that this would approximate estimated real GDP growth + expected inflation rate.

I say this because GDP growth is going to be contributed by business and a dominant proportion of Indian business is listed.  Moreover, I believe businesses, overall, should be able to pass on rising costs to the end consumer to a large extent (although not perfectly) and hence, cover a large part of inflation as well.

Based on my understanding of consensus estimate – a conservative estimate for real GDP growth over the next 10 years should be 8%+ (based on current growth rates and an assumption that the demographics, consumer buying power and current state of politics will continue as the last 10 years) and inflation should be at most 5-7% (based on RBI determination to bring down current rates of 9% and establish some sensible real yield for the 10-year bond).

This equates to nominal growth rates of 13%-15% per annum.

This is obviously subject to substantial risk of change as economic factors vary.  This growth rate should, however, serve as a reasonable benchmark to value profitable Indian businesses on an overall basis.

  1. what a good post man....can you tell what will be expected growth rate of banking industry...is it 13-15% or more than that...somewhere close to 20--25 % ...please throw some thought...because somewhere i have read that banking industry have to grow faster than others in order to keep economy moving as they are the source of credit...

  2. Thanks for your remarks. You ask an interesting question.

    Unfortunately, I am not an expert on the banking industry. I tend to avoid banks for the moment because I don't yet have a grip on the loan/investment portfolios and management quality of individual banks. These are vitally important given their leverage and small errors tend to wipe out (or materially dilute) banks' equity.

    I would think that banks' equity growth (as other industries) would largely be a function of Returns on Equity x Retention Rates (assuming future profitability is similar to past). And obviously, these growth rates are likely to vary widely between banks.

    I don't think there is a necessity that they would have to grow faster than the rest of the economy because that would be a function of increased penetration of credit within Indian society and that is not a certainty (although it is forecast).

    On receiving your comment, I came across reports that forecast above average growth (>13-15%) for private sector banks, presumably as a result of their greater profitability and efficiency, and average growth (as well as below average growth) for public sector banks for the opposite reasons.

    That's the best I have on the banking industry at the moment - and I'm open to correction of glaring errors in my statements above.

On The Radar: India's Small-Cap Equities (Concluded)

We have been running a series of articles titled ‘Under The Radar: India’s Small-Cap Equities’ beginning in December 2011 - and followed up twice - with the last article in December 2013. We would like to conclude this series after updating the small-cap index level and returns, comparing it to our expectations ex-ante, and analysing the current scenario.  Following this, we have also outlined where we may take this blog in the future. The small-cap index closed at 11,087.07 on December 31 st , 2014.  This compares to a level of 6,150.65 in our last article – resulting in an advance of over 80% to date. This is a handsome absolute return by any standard, particularly compared to Indian government bonds, which yielded around 8-9% for the period.  This justifies the conclusion at the end of our previous article that “small-caps in India offer among the most attractive bargains during any time since 2006 and certainly in the entire Indian stock market today...

Under the Radar: India’s Mid-Cap and Small-Cap Equities

Indian stock markets have been one of the worst performers in 2011 – worse than their BRIC peers, worse than the rest of Asia and far worse than the US with the leading indices declining about 25% during the year.  Foreign investors in India have also suffered substantial declines of nearly 20% in INR currency value. There appear to be several reasons for the market’s dislike for Indian equities in 2011, which include persistent inflation (including food inflation, which constitutes the major proportion of the typical Indian household), political paralysis (e.g. rollback of foreign investment in retail etc.) and global concerns about the solvency of several Eurozone countries. As a result, estimated GDP growth for the next financial year has been revised downwards from about 8% earlier in the year to about 6% now - with many market commentators wondering whether this rate of growth is India’s ‘new normal’.  This is still, however, substantially higher than global av...

Under The Radar: India’s Small-Cap Equities (Part Three)

In February of this year, we summarised the valuation parameters of the BSE Small-cap Index in India (now the S&P BSE Small Cap Index) - following on from an earlier report we wrote in December, 2011 - and drew certain conclusions. We would like to update the valuation scenario with the data today, review those conclusions, and form new ones based on the available information. The small-cap index closed today (17 th December, 2013) at 6,150.65 with an indicated price to book value of 1.04. The closing value as on February, 2013 was 7,006.73 representing a decline of over 12% as of today. The current index value masks a greater fall of over 27% to a low of 5,085.56 in August, 2013. This represents an unsatisfactory overall performance for those who invested in small caps at the beginning of the year. In our earlier report, we made two assumptions towards the end of our report to form a conclusion as to prices then:          ...
