Let's try an experiment. Sell the OCT QQQQ 39 call, and buy the 40 call, for a .50 credit. This is a vertical credit spread. Maxium gain is the .50 credit. Maxium loss is the difference between the spread and the credit, or 1.00 - .50, for .50 risk. One reason I don't like this is that I would rather have the nice round number 40 as my short and buy the 41 to hedge. But there is not enough premium worth doing this. Will check back occasionally to see how this is working.
If you are bullish and think the market will throw a curve ball by having a big rally into October, you could BUY the 39 call and sell the 40 call (to reduce the price) for .50 debit. This is a vertical debit spread. Your maximum risk is the .50 debit, and the maxium gain is again, the difference between the strike prices and the debit, or .50.
There never was a moment, and never will be, when we are without the power to alter our destiny. This second, we can turn the tables on Resistance. This second, we can sit down and do our work.
