Over the past two trading days, the S&P 500 has gained 7.5%. S&P quantitative analyst Andre Archambault informs me that over the past 40 years, two days of this magnitude or larger are very rare (it's only happened four times since 1962). On the trade that would equate to Monday's session, three out of four times saw an average closing gain of 2% for what would be this Monday, the one time that gains did not occur, the loss on the day was 3.9%.
Most of the earnings warnings are probably out of the way and the markets might receive earnings reports which at least are simply meeting expectations (which would limit the downside). I still expect jagged trading and risks for sub-800 S&P 500 closes have not been eliminated.
October has a reputation for being a bear killer (meaning some big bear markets have ended in October), prices can push lower in the beginning of the month and then prices can rebound in the second half of the month and I think that is what is happening to these markets.
