Trend Trading

Is trend trading that easy?

BUY when 200sma slope is positive and stock crosses above 200sma.
SELL when 200sma slope is positive and stock crosses above 200sma.
CAREFUL when 200sma slope is negative.

I have not back tested the strategy; hence, I don't know how effective it is.

If it was that easy, then why most money managers cannot even beat the index.

Easy in hindsight, isn't it?
