Nov 1st: FB reports at market close. Nov 2nd: AAPL reports at market close. Nov 2nd: BABA reports before market open. The influence of earnings on any particular trade, good or bad, are 4 times a year external influences on the trading system. They offer the opportunity for great reward, at the cost of great risk. In advance of earnings I take off at least 1/2 of any then open position. This strategy may or may not fit everyones risk:reward profile. The official portfolio will hold through earnings, because it's a robot and is void of emotion. We are working on that.
