Sir Isaac Newton was a prominent physicist and one the most influential men in human history. Newton's third law of motion stated that "to every action there is an equal and opposite reaction". If that law is applied to the stock market it could mean that the horrible, unrelenting bear market of 2008 will be reversed with a roaring bull market in 2009. While that may happen, I don't think that's it's very likely. Today's rally was nice, but stocks finished off their highs for the session which does not augur well for tomorrow.
