I've found that it has gotten very hard to do a momentum trade in the last 6 months or so. I used to be able to make quick trades profitable at least 9 out of every 10 trades. Now, not so much. The buy and hold is the only thing that's been working. It's like this - most trades i make now take a few days to actually show a profit. It seems like the timing of the buy is not what it used to be.
Can't complain - they eventually almost always turn good, but i used to be able to time the buys better. I think it's these algos at work. It's almost like I'm being set up, I take the bait, and then the algo boys take their profits.
I'm trying to be smarter about it, like today, almost bought some more Apple near the high, but recent experience is telling me that's a sucker's play, so will watch for a shot at it sometime in the future. And sure enough, sold off into the close (probably Maserati selling his shares?)
