When investing I often try to look at macro trends of commodity's or securitys to profit on a bottom reversal. Once a commodity has bottomed to a support level where the market has enough support and the supply starts to go down the commodity price will often go back up in a reversal thus is where you have to watch closely to time the market correctly to be able to make a nice profit and sell when it goes back up.
I am keeping an eye on potash I think the commodity might finally be at a bottom or close to it. Potash has been in a 10 year down turn cycle of the commodity just going down. Once this commodity has finally found a bottom I plan to buy shares of company's that sell potash such as Potash Corp (POT) and Agrium Inc. (AGU).
