Technical analysis is very relevant.
Although I'm not a chartist, I do use charts for trends, support and resistance points, I would be a damn fool not to.
Hedge funds bulley their way through the market, and many times don't get the prices they should. One of these days, the regulators will be chopping away at hedge funds.
Money Mangers most certainly do use technical analysis..
So you can go ahead and trade blindly by not using technical analysis, it's your money.
As an investor, you may not always get the bottom, but you'll be darn close, you may not sell at the top, but you'll be close.
Fundamental analysis can tell you what to buy/sell and Technical analysis can tell when to buy/sell
