I've always found Ben Graham's Mr. Market allegory to be useful. To me, it's as relevant as ever.
Ben's Mr. Market allegory may seem out-of-date in today's investment world, in which most professionals and academicians talk of efficient markets, dynamic hedging and betas. Their interest in such matters is understandable, since techniques shrouded in mystery clearly have value to the purveyor of investment advice. After all, what witch doctor has ever achieved fame and fortune by simply advising 'Take two aspirins'? - Warren Buffett in the 1987 Berkshire Hathaway Shareholder Letter
It's a simple but useful idea. Mr. Market experiences extreme mood swings and, as a result, often wants to sell or buy businesses well above or below intrinsic value.
So not a new idea but still just as useful today as ever if you are a long-term investor. Certainly more useful than the myriad technical approaches that are so popular (traders probably have a different view...I can't speak to that).
Having said that, Bespoke Investment Group does provide some great statistics on markets for those that are more interested in this stuff than I. Here is one of their posts from this morning comparing the current bull market to past ones going back to the 1920's.

This site does not provide investing recommendations as that comes down to individual circumstances. Instead, it is for generalized informational, educational, and entertainment purposes. Visitors should always do their own research and consult, as needed, with a financial adviser that's familiar with the individual circumstances before making any investment decisions. Bottom line: The opinions found here should never be considered specific individualized investment advice and never a recommendation to buy or sell anything.
