Long time readers know I tend to be a bottom feeder. Witness the AAPL thing recently and several others that have fallen out of bed to support levels.
As for longer term bottoms, they have not been worth buying until recently when the precious metals put one in that looks to have good potential. This one in Agriculture ETF DBA looks like it has potential as well with a break up by MACD and RSI after months of bullish divergence.
It needs to turn the 25+ area into support.
