S&P 500 (SPY) 397 first level of support and 404 first level of resistance. The 50-week MA looms above as overhead resistance 410. Until that clears, this could return to support at the 50-DMA or 380.
Russell 2000 (IWM) 177 key support and 183 first level of resistance. Similarly, 190 is resistance and now looking at 177 as support and must hold.
Dow (DIA) 337 first level of support and 344 resistance. As the only index above the 50-WMA, support at 329 is key.
Nasdaq (QQQ) 284 first key level of support and 292 resistance. Still the weakest index. Hovering on major support at 278 or trouble ahead.
