S&P 500 (SPY) 393 first level of support and 398 resistance. The 50-week MA looms above as resistance 410 - until that clears, this could return to support at the 50-DMA or 380.
Russell 2000 (IWM) 177 support and 183 resistance. Similarly, 190 is resistance and now looking at 177 as support and must hold
Dow (DIA) 333 first level of support and 339 resistance. As only index above the 50-WMA, support at 329 is key.
Nasdaq (QQQ) 280 first level of support and 287 resistance. Still the weakest index. Hovering on major support at 278 or trouble ahead.
