Every trend that led to the late February market meltdown has suddenly reversed. The Japanese yen has gone from hero to goat again. Ditto for the Swiss Franc. Stocks are soaring instead of plunging. Bond prices are falling after rallying. The general consensus: It's all sunshine and roses again, the mini-crash was nothing but a flesh wound, etc., etc. Am I the only one who's a tiny, wee bit skeptical about this "Opposite Day?"
