In its quest to regain its 2013 mojo, the S&P 500 has broken back above its 50-day moving average as well as the 1,635 resistance level. The index now has two more resistance levels to take out before the May 22nd-June 24th pullback can officially be declared dead. The first level is at 1,654, which is just a point or so above where the index is currently trading. The second level is at 1,687, which is the index's all-time intraday high. These are the two levels to watch over the next few days.
