S&P 500 closed today above key level, which is the downtrend border in relation to 1-year and quarterly mean.
The level is the lower 1st standard deviation from 1-year and quarterly means aligned, now standing at 197.5
The close above cancels downward risk that was initiated during late August selloff - and if price trades above it from now on - it will likely to continue its lateral uptrend, started back in the beginning of 2013
