re: Time to buy some XOM(Oil stock discussions)?

I'm likely late to the game with SCO: + 79% over the past three months, + 259% over the past year. But as a means to go short (or long), without delving into futures or options on futures, I definitely see that I need to expand my game into ETF trading.

I know there are a couple of others here who trade fairly frequently. Which ETFs have you been following? We can stick with oil, since that's what the OP is about. But if you want to bring up any other sectors, that should be OK.
