The market had a very strong snapback rally on Thursday from a deeply oversold condition. The day started with a gap up. They pulled back, tested the intraday moving averages successfully and then exploded to the upside. At that point they settled into a shallower angle of ascent, but nevertheless stair-stepped their way higher all day. They did pull back in the last hour, but in the last 10 minutes snapped back once again to close not far off the session highs.

Net on the day the Dow was up 199.89 at 9962.58, the S&P 500 up 23.48 at 1066.11, and the Nasdaq 100 up 29.21 at 711.27. The Philadelphia Semiconductor Index (SOXX) was up 3 percent, or 6.48, at 307.26.

Stepping back and reviewing the hourly chart patterns, it was up at the get-go and then strongly higher early on before settling into a shallower angle of ascent, but a steep one nonetheless.
