Unless they're day traders (in which case, SMT surely isn't the best investment vehicle), I don't think you should pay much attention to one day price movements (up or down). Particularly when global markets are as jittery as they have been today.
If anything, today's weaker than expected US job & unemployment numbers pretty much guarantee an interest rate drop there next month. Which should be good for shares generally - and the sectors SMT holds in particular - especially if it's the start of a long term downwards interest rate trend (which it almost certainly will be).
Excluding dividends, SMT is still up almost 15% over 1 year & 49% over 5 years. Not great admittedly, but not a total disaster either. Screen out one day, even one week or one month white noise and take a long term view. And if that's still negative, fair enough - go ahead & sell.
