Its not so sweet over 35

I have kept trading on yahoo and never lost so far fortunatelly.
My way of making money off it is I rarelly buy it over 34. My desired buy in price is from 33-33.50.
I got it a little higher two days ago at 34.09 in the expectation it would go up alot with a good earning report, but it didn't,so I sold it today at 35.40 using market stop to keep profit.
The momentum for its continiously going up might be over by tomorrow, and all that I need to do for now is to patiently wait for it get back to my 33 target price range again.
