S&P 500 heads for lows of the session after the first hour, levels to watch

The index is down half-a-percent at time of writing, continuing the slow roll-over evident now for several weeks. The only sector clinging to positive territory is Technology, though it may soon fade to negative as well depending on Apple (AAPL) and Google (GOOG). Cisco (CSCO) remains the strongest component within the sector. On the downside, leaders are Materials, Utilities, Industrials, and Financials. At the current index level of 1368.71, support is at 1365.45, and then at 1357.26. Resistance is at 1371.39, the low of yesterday's session.
