Exactly. A lot of the recent down action on Wall Street is tax trading. Capital gains taxes are expected to rise in 2013. Investors aren't going to be tax traders, though, and their best strategy is to ignore the static. If you keep to a long time horizon, it doesn't matter what happens over a period of weeks or even months.
This. I've been saying this for weeks. So much uncertainty of the future of taxes and the overall market there seems to be a major sell while the gettin is still good.
