I guess that's true for people who don't know how to do it..
Have you never noticed resistance and support levels on a stock?
Have you ever noticed a stock that has went straight up or straight down usually retraces? It's true that fundamentals and news are bigger drivers at times, but NEVER underestimate the amount of $$$ you can make from TA. Have you ever heard of RSI which shows when a stock is overbought and oversold? Dude you need to get with the program and face reality or miss out on big $$$ IMO.
Buy and hold is an OK strategy, but you can make a lot more having a trading portion in your position that you sell when it gets overbought (i.e. up too fast) and buy back on big dips (down too fast). It's really quite simple IMO and in no way is like throwing darts, in fact, to me it seems like common sense to know that a stock will not go in a straight line one way or the other, thus selling dips and buying rips makes perfect sense.
