A moving average is not a trend line. It's difficult to have a meaningful discussion if we are talking about two different things. As for false positives, nobody reasonable will tell you that they don't exist. But again, there's a difference between short, intermediate and long-term trend lines. Even under the most unfavorable scenarios, anybody with a modicum of knowledge of trend lines would have been out of the market before the 2008 crash and back in the market by early 2010 because major trend lines were broken. Incidentally, I was one of those people. As for your advice: there's nothing wrong with fundamental analysis. Although many people fail to make money using it (just like technical analysis), it's worth noting that quite a few savvy professionals use fundamental and technical analysis together.
