It is a testament to the psychological power of financial bubbles that people who know and trust me and generally accept the analysis I've put forth in my writings over the last decade are jumping into the stock market again with a pledge that they are in for the long term--no matter what.
Few would ever shop for a car, a house or even groceries the way people today are shopping for stocks--buying after the price has almost tripled. But a market experiencing a dramatic melt-up--26 percent for the S&P 500 last year and another 5 percent so far this year (8 percent when I first wrote this sentence)--has created a psychological contagion that is hard to resist. Who doesn't want to join in the mass euphoria experienced by others who are getting something for nothing?
Now there was a time when investing in the stock market for the long term worked because the businesses that made up that market were supported by unconstrained supplies of energy and other critical resources. The undulations in the economy were due primarily to economic cycles. But as economist James Hamilton has pointed out, 10 of the last 11 recessions were preceded by an oil price spike. That's not definitive proof that the oil price was THE cause of any particular recession. But it would be hard to rule out oil as a major factor in those recessions.
