II. b) Market Valuation and Long-term Trend
Understanding of the current market level is essential for successful investing. It should provide guidance for your investment stance: is it advisable to be active or passive, hedged or fully long.
Alice Schroeder started her brilliant The Snowball, the best book about life of Warren Buffett, with a memorable lecture the value investing grandmaster gave to the wealthiest and successful businessmen back in 1999, a few months before an important market top.
In the long run economy grows because of fundamentals: population size and productivity change. Stock prices depend on profit size (% of GDP gives a good perspective, too) and multiple of earnings, which is dictated by prevailing interest rates and inflation expectations – gravity force of the market. Share price can go up via growing profits and expanding multiple. Dividend payback is also a very important part of the total investment return. That is a brief summary of how the markets work in the long term.
In 1999, W. Buffett made his first prediction in 30 years that market would grow by 6% annually for the next 17 years (he highlighted a period between 1964 and 1981 when Dow Jones Industrial moved from 874 to 875 while economy grew fivefold).
Dow Jones in July 30, 1999 - 10,655
Dow Jones in July 31, 2011 – 12,143
17.27% up in 12 years or 1.1% annual cumulative returns. Presently, it seems that W. Buffett was an optimist and based on his frequent and recent media appearances he still is. We have 5 years to go, so who knows… And you have to remember that he speaks his book.
From 1900 to 2011 S&P 500 generated 5% cumulative return (dividends provided another 4%+). Coincidentally, 4.8% is a historical S&P 500 profit growth rate and 6.2% is historical nominal GDP growth rate (Ed Esterling’s Crestmont Research website). Long term simple average inflation is 2.9%, population growth rate is 1.3%, therefore, the rest (or 2.0%) is productivity driven growth. Noteworthy, GDP growth is slowing down during the last 30 years because accumulated leveraged started to weight economy down.
“Exhibit 1, the “Exhibit of the Quarter,” shows the incredibly low volatility of the U.S. GDP, which two-thirds of the time has a volatility that is a mere ±1% around its long-term trend of about +3.5% a year real. This trend is stable because the economy is mean reverting, and bad times (like the 1930s) that produce spare capacity in both labor and capital are followed by strong times as the economy works to use up its excess resources. This ultra stable GDP engine can be thought of as the engine driving corporate profits and dividends. They in turn, although far less stable at a yearly level, follow the GDP in its mean reverting tendency towards a ‘normal’ level. Because of this, if you were clairvoyant in 1882 about the entire actual stream of corporate earnings and dividends until today, and used your clairvoyance to calculate a fair value, and then did the same for 1883 and so on for every year, it would produce a very stable trend of stock market fair value, as first revealed by Robert Shiller 18 or so years ago. Perhaps, not surprisingly, the volatility of this fair market value also stays within ±1% of its long-term trend two-thirds of the time. But what a contrast these two series are to the actual stock market, which manages to spend two-thirds of its time within only ±19% of fair value. This means that the market is 19 times as volatile as the underlying fundamentals would seem to justify! Understanding this 19 to 1 discrepancy would put us a long way along the road to understanding risk.”
A few highly respectable investors estimate that now fair market value of S&P is 900-1,000 (2012), which probably means that it is better to be cautious.
Media pays most of attention to short term forecasts, which are mainly based on estimated next year’s operating earnings. It may really look reasonable to apply 10-15 earnings multiple to a basket of equities, however, one has to remember that currently profits command unprecedentedly high share of the economy, which - history tells - should mean revert. Problem is that nobody knows when.

Make your own conclusions but I am fully hedged.
