If ES are ever -2 or more in the morning. Buy. Close out later in the day for a profit at a time of your choosing. Doesn't really matter when. But closer to 4pm the better. And never fear, if you fail to sell by 4pm, they are usually a bit higher between 4:00 and 4:15. Strategy 2. Should ES not be -2 or more in premkt. Go ahead and buy anyway. Think about it. There really is almost zero risk. What could happen? market 20% undervalued and Cramer says we headed higher.
