I guess my perspective is that there is a spectrum of investment horizons that runs from seconds to years, and different techniques work more or less well over those horizons. I've always had a strong background in fundamentals, and think (and results would suggest I can prove) I have an edge there, but there is a point at which fundamentals break down and become useless, and for me that is on timeframes of much less than a month. Moving to TA, I never managed to find a consistent edge. First year was very good, but there was a lot of beta in there, second year was more modestly up, but with too much volatility to comfortably say, right I'm going to close off other avenues and really focus on making this work. Plus by that stage I was missing 'going to work', and frankly getting a bit bored of staring at screens of charts all day. So I gave up doing something I wasn't sure I had an edge in, to a time frame where I think I do - at what point that moves from 'trading' to 'investing', I'm not sure, but that's where I am now, and I'm very happy with the decision. Plus a little bit of the TA I worked on for two years helps on timing entries and exits on the fundamental side.
