I have a skylight in the ceiling of my bedroom, and this morning, when I woke up, it looked as if someone threw diamonds on it. It must have rained at night, and then it got colder, freezing the raindrops into clumps of ice. Today is March 1, and just two days ago the weather was so warm that I could walk outdoors in a shirt. Does last night's ice mean that the winter is back?By now we've been in a bear market for almost a year and a half. The broad stock market indexes, such as the Dow and the S&P, have lost over 50% of their value, with many individual stocks losing much more. Last Monday, Feb 23, the Dow broke its 2002 low, with the S&P holding one point above its own low, and then both rallied. On Friday, both the Dow and the S&P fell to new bear market lows, with the S&P breaking below its 2002 level.
