This Is Now The Worst Possible Environment For Stock Market Investors

What do I mean by “worst possible environment”? I mean an extremely overvalued, over-bullish stock market that now finds itself in a downtrend.

Let’s take a look at these individually. As for “extremely overvalued,” I prefer to look at Warren Buffett’s favorite measure of market cap-to-GNP. It shows that only during the height of the dotcom bubble were stocks more expensive than the are today. In fact, today’s valuations are roughly equivalent to November of 1999.
