The bull market in stocks turned 8 years old last week. This is the second longest bull market in stock market history. The longest was the bull market in the S&P 500 that ended in March of 2000 at the height of the dotcom blow-off. We all know what happened when that bull market ended. It doesnโ€™t offer much encouragement for whatโ€™s to come when this bull market ends.

Nor is it encouraging that since the March 2009 lows, the S&P 500 has increased by nearly 250%, but earnings have only doubled. The other 150% gain in prices is purely a function of investorsโ€™ willingness to pay an ever increasing price for the same dollar of earnings. Eight years of zero percent interest rates apparently has a powerful effect on investorsโ€™ perception of value.

As Jim Grant of Grantโ€™s Interest Rate Observer recently put it, โ€œGrateful investors may address a note of thanks to the Federal Reserve Board, 20th St. and Constitution Ave N.W. Washington, D.C. 20551.โ€
