In the U.S. stock market, it's all going to end badly. Even some ardent bulls will freely admit to it. The question is how, when and where.

Frankly, a tragedy is unfolding, and discerning eyes can see it. Since the December lows, the stock market has taken the scripted route higher, salivating at the prospect of dovish central bankers once again levitating asset prices higher. It's a Pavlovian response learned over the past 10 years. Record corporate buybacks keep flushing through the market, and cheap-money days are here again as yields have dropped markedly since their peak last fall.

But investors may sooner or later learn the hard way that this sudden capitulation by central bankers is not a positive sign, but rather a sign of desperation.
