Do you think Citigroup's dividend is safe?

If you had to choose one stock to play the exchange market and the recent volatility, would you buy IntercontinentalExchange, NYSE Euronext or CME Group?

With oil at an all time high, the oil-related stocks, refiners and drillers, are obviously getting influenced. Is my understanding correct in that the cost of oil will influence the earnings and the stock price of all these companies?

I did my homework on Intuitive Surgical and Google and got in them on Oct. 15 and 18.
During the Oct. 19 downturn I actually found my portfolio up 0.2%!

Is First Solar cheap? Even with the stock's recent run-up, it seems to be trading at 108 times next year's earnings and I calculate a target price of $356. So treat it like a Google when trading/investing? What do you think?

This isn't a stock question; it's a defense question. Instead of getting fancy shmancy with options/derivatives (which I don't understand anyhow), can't I simply put stop limits under my best performers so this pig doesn't get slaughtered?
