Positive news on the war front has sharply affected the markets. The added speculation that Iran may actually wish to normalize relations a bit has eased the absurd oil market (gawd I wish we would pour $ into developing renewable, home-grown fuel sources!!). Unemployment is exceptionally low. Housing market continues to exceed expectations. Manufacturing is up. The deficit reduction is exceeding expected pace. And it is rumored that the Fed will NOT raise rates!
Give it a few days... it'll dip again. Like everything else, the markets are cyclical.
