Yesterday's enthusiasm was nowhere to be found as stocks do an about-face and head south, finishing at or near lows. Dow was the biggest loser, -2.03% (-171.88) to 8,301.61. S&P gave up 900 just as quickly as it retook it yesterday, -1.9% (-17.27) to 893.06. The index hasn't managed a two-day rally since May 4. Nasdaq -1.11% (-19.35) to 1,731.08.
