Options Wonderland

[goodfoot]

Lang, Wonderbuy, and everyone else:

I need just a bit of knowledge on call/put "picking". Right now, I've been picking the direction of the stocks pretty well, but I think my selection of calls/puts to purchase been so good.
Case in point: LDK. Stock drops like a rock intraday yesterday and the Mar15p that I own (DLOOC) didn't even budge. WB gave me some insight about time premiums the other day and I've been buying recent puts on shorter time-frames. After you've zeroed-in on the stock you want to target for profit, is there a "rule-of-thumb" that is to say, a quick reference that would help me pick the actual options that I buy better. Also,
Thanks in advance. Have a great thanksgiving everybody!!
