One that got away from me - DBB (Base Metals)

DBB - This is the base metals ETF. I got too cute a month or so ago and wanted to get a better entry. Kept waiting and now it's run 20% away from me. Whenever I see that thing green on my screen it screams "Why did you try to get too greedy on an entry for a longer term holding - you should have just bought me, idiot?"... and I think "You're right, DBB... you're right."
