Optik says in regards to purchase points;
"When "people in the know" make their move you usually won't have a chance to buy if you don't own already. Maybe you can get in near the top and make a few bucks. Maybe? It's just the way it works. Then I'm sure you know this."
I say I generally agree with that, by the time you see an SEC filing on insider trading it is too late. However identifying an upward trend volume/price is much easier. In speculative/high risk issues I definitely prefer to buy on the way up.
It is kind of like getting a baby to sleep on it's own throught the night without waking up for feeding.
1 day is a fluke
2 is a coincidence
3 is trend.
Good Luck
