I have strong opinions about stock options, and my posts on the subject have been among my most popular (“Stock Options – Wilson’s Rules” and “Stock options – everybody in the pool“). For those of you who want a more basic introduction to stock and options, David Weekly just wrote a great primer on the subject. Check out his Scribd document: An Introduction to Stock and Options. It’s everything you need to know.

Jay,
That’s is definitely worth reading. I learned it by experience. Wish I read it before starting Accousitc Imaging.
Thx, Dan
Glad you enjoyed it! Let me know how it might be improved further!
FYI – a Third Edition is now out! Check out http://dweek.ly/stock for the online version as well as an hour-long talk I gave on the subject.
