Depends how much you already have. If you already have a good % of your money in IMSC, I'd leave it at that. If it's under 5%, I'd add.
Thing is... with such a market pullback this week, you can pretty much throw darts, buy those stocks and you will most likely make good money.
Personally, I am building SVXY position (volatility short) and buying good names like PANW, AAPL, SWKS, etc.
