For simplicity I pool my cash. I don't even think about it for my funds but will stop.throwing money at my individual stocks. I think of myself as a lousy stock picker though I own a few.
The good ones for me have been SCCO, WPM, and WRI. A few bad ones have been DHT, STKL, FCEL, PLUG.
I would reccomend staying away from leveraged funds for the same reason that individual stocks are problematic.( they can go down too much)
I try and slap my wrist when I think of buying individual stocks.
Aiming and investing can be as simple as you want to make it.
1)Just own an S+P 500 fund
Or
2) own large, small, foreign, REIT funds. No need to own bonds as AIM will have you holding cash ( part of which COULD be in a short term bond fund).
Of course you COULD use any other system of diversifying ( check of PAUL MERRIMAN or PERFECT PORTFOLIO for other ideas)
The important thing is to decide on a plan and stick to it. Some years it will do better than the market, some years worse. Even AIM with just the S+P 500 will do worse in an up trending market. But the losses will be less on the way down.
