Hedging Against Falling USD in a Stocks ISA?

[brettb]

I've been trading quite a lot of US stocks in my ISA. While my trading is profitable I'm being hit quite hard by the recent dollar weakness. My non-ISA account is using the same strategy with UK stocks only and it's been hitting new all time highs.

Is there anything I could do to hedge against a weaker dollar? Buy more stocks? Hold treasurys or inverse treasurys or something? Or just buy more US stocks when the pound is stronger?

I guess GBP is in a multiyear bear market against USD so maybe it won't matter in the longer term.
