Mail Block/Options Question of the Week: Twitter poll AND listener questions and comments

What is most important to you when choosing an options broker?

1. Commissions
2. Platform Features
3. Support/Service

4. Educational Offerings

5. Question from Grasshopper: I have heard options strategies may be vulnerable to "dump like an elephant" concerns criticism. Are the losses big, are high win rate strategies a cause for suspicion?

6. Question from Fred: Would trading options change that way I look at/trade futures?
7. Question from Anthony Cioffi: I have got a somewhat off-topic question from the show. I know Mark is a fight fan. What does he think of the recent sale of the UFC for $4.2 billion?Good deal, or did they dramatically over pay? What are the odds that the UFC will eventually go public as a result of this deal? It would be fun to trade options on that name. They would probably be very volatile heading into big fight cards.
