From www.sentimenTrader.com this morning...

This is only the 10th time in the history of the benchmark S&P index (dating back to 1928) that it gained at least +0.75% for five straight days.
After 7 of the other 9, the index dipped the next day. But 8 of the 9 times, buying the next day's close and holding for two weeks resulted in gains.
