I haven't traded this particular UK stock at all, but again the chart below shows how in 2012 you could have profited both with long and short trades, against buying and holding which would have meant you've made...nothing.

All these charts I've posted recently are with exactly the same parameters, timeframes and entry and exit criteria. If a system is robust enough, and not 'curve-fitted' them such a system will work whether it's stocks, indices, currencies, interest rates etc.  My own preference is to trade stocks, but trend following has its roots in trading indices, commodities and the like.
