My background with industrial machinery taught me that closed loop controls are marvelous things. AIM emulates just this sort of thing. Technical analysis attempts to make efficient, profitable trades based upon an investment's own price activity. This is fine. This can work well - especially in a perpetually rising market.
Fundamental analysis looks into the business of the investment for other information.
It takes time and effort to do good analysis. Usually fundamental analysis will include decisions about whether there is good long-term viability in the investment. I concentrate on the Fundamental Analysis portion first. If I'm going to devote the time to Fundamental Analysis then short-term trading doesn't usually pay. I'm trying to pick investments that I'll own for 5 years or longer.
