Ah, the perennial question that springs to mind when the purchase initially goes against you.

Not knowing your comfort threshold, I recall a general rule of thumb that if you are down 10 per cent of the purchase price, SELL without hesitation ( This theme comes through in a number of books on share trading and market/investor psychology, as well as in "Reminiscences of a Stock Operator" )

This leaves you with most of your capital intact, ready to try again another day.

Also, buying closer to an uptrending moving average rather than jumping into a spike is more useful for the longer term holder.

I don't hold CRS.

Hope this helps.
