How Inflation Swindles the Equity Investor - by Warren E. Buffett, FORTUNE May 1977
It is no longer a secret that stocks, like bonds, do poorly in an inflationary environment. We have been in such an environment for most of the past decade, and it has indeed been a time of troubles for stocks. But the reasons for the stock market's problems in this period are still imperfectly understood.

Five ways to improve earnings
-
Must we really view that 12 percent equity coupon as immutable? Is there any law that says the corporate return on equity capital cannot adjust itself upward in response to a permanently higher average rate of inflation?
-
There is no such law, of course. On the other hand, corporate America cannot increase earnings by desire or decree. To raise that return on equity, corporations would need at least one of the following: (1) an increase in turnover, i.e., in the ratio between sales and total assets employed in the business; (2) cheaper leverage; (3) more leverage; (4) lower income taxes, (5) wider operating margins on sales.
-
And that's it. There simply are no other ways to increase returns on common equity. Let's see what can be done with these.
.....
The investor's equation
-
Even if you agree that the 12 percent equity coupon is more or less immutable, you still may hope to do well with it in the years ahead. It's conceivable that you will. After all, a lot of investors did well with it for a long time. But your future results will be governed by three variable's: the relationship between book value and market value, the tax rate, and the inflation rate.
-
Let's wade through a little arithmetic about book and market value. When stocks consistently sell at book value, it's all very simple. If a stock has a book value of $100 and also an average market value of $100, 12 percent earnings by business will produce a 12 percent return for the investor (less those frictional costs, which we'll ignore for the moment). If the payout ratio is 50 percent, our investor will get $6 via dividends and a further $6 from the increase in the book value of the business, which will, of course, be reflected in the market value of his holdings.
-
If the stock sold at 150 percent of book value, the picture would change. The investor would receive the same $6 cash dividend, but it would now represent only a 4 percent return on his $150 cost. The book value of the business would still increase by 6 percent (to $106) and the market value of the investor's holdings, valued consistently at 150 percent of book value, would similarly increase by 6 percent (to $159). But the investor's total return, i.e., from appreciation plus dividends, would be only 10 percent versus the underlying 12 percent earned by the business.
-
When the investor buys in below book value, the process is reversed. For example, if the stock sells at 80 percent of book value, the same earnings and payout assumptions would yield 7.5 percent from dividends ($6 on an $80 price) and 6 percent from appreciation - a total return of 13.5 percent. In other words, you do better by buying at a discount rather than a premium, just as common sense would suggest.
-
During the postwar years, the market value of the Dow Jones industrials has been as low as 84 percent of book value (in 1974) and as high as 232 percent (in 1965); most of the time the ratio has been well over 100 percent. (Early this spring, it was around 110 percent.) Let's assume that in the future the ratio will be something close to 100 percent - meaning that investors in stocks could earn the full 12 percent. At least, they could earn that figure before taxes and before inflation.
-
7 percent after taxes
-
How large a bite might taxes take out of the 12 percent? For individual investors, it seems reasonable to assume that federal, state, and local income taxes will average perhaps 50 percent on dividends and 30 percent on capital gains. A majority of investors may have marginal rates somewhat below these, but many with larger holdings will experience substantially higher rates. Under the new tax law, as FORTUNE observed last month, a high-income investor in a heavily taxed city could have a marginal rate on capital gains as high as 56 percent. (See"The Tax Practitioners Act of 1976.")
-
So let's use 50 percent and 30 percent as representative for individual investors. Let's also assume, in line with recent experience, that corporations earning 12 percent on equity pay out 5 percent in cash dividends (2.5 percent after tax) and retain 7 percent, with those retained earnings producing a corresponding market-value growth (4.9 percent after the 30 percent tax). The after-tax return, then, would be 7.4 percent. Probably this should be rounded down to about 7 percent to allow for frictional costs. To push our stocks-asdisguised-bonds thesis one notch further, then, stocks might be regarded as the equivalent, for individuals, of 7 percent tax-exempt perpetual bonds.

The number nobody knows
-
Which brings us to the crucial question - the inflation rate. No one knows the answer on this one - including the politicians, economists, and Establishment pundits, who felt, a few years back, that with slight nudges here and there unemployment and inflation rates would respond like trained seals.

What widows don't notice
-
The arithmetic makes it plain that inflation is a far more devastating tax than anything that has been enacted by our legislatures. The inflation tax has a fantastic ability to simply consume capital. It makes no difference to a widow with her savings in a 5 percent passbook account whether she pays 100 percent income tax on her interest income during a period of zero inflation, or pays no income taxes during years of 5 percent inflation. Either way, she is "taxed" in a manner that leaves her no real income whatsoever. Any money she spends comes right out of capital. She would find outrageous a 120 percent income tax, but doesn't seem to notice that 6 percent inflation is the economic equivalent.
.....
The way it was
-
Let's assume that about half of earnings are paid out in dividends, leaving 6 percent of equity capital available to finance future growth. If inflation is low - say, 2 percent - a large portion of that growth can be real growth in physical output. For under these conditions, 2 percent more will have to be invested in receivables, inventories, and fixed assets next year just to duplicate this year's physical output - leaving 4 percent for investment in assets to produce more physical goods. The 2 percent finances illusory dollar growth reflecting inflation and the remaining 4 percent finances real growth. If population growth is 1 percent, the 4 percent gain in real output translates into a 3 percent gain in real per capita net income. That, very roughly, is what used to happen in our economy.
-
Now move the inflation rate to 7 percent and compute what is left for real growth after the financing of the mandatory inflation component. The answer is nothing - if dividend policies and leverage ratios remain unchanged. After half of the 12 percent earnings are paid out, the same 6 percent is left, but it is all conscripted to provide the added dollars needed to transact last year's physical volume of business.
