Ah ok, I misread your post sorry, had the figure coming up. Yeah I like shorting £ against the Yen, I actually have on that position albeit probably too small. It's certainly a more "clean" position and not exposed to the US QE risks.
This US report certainly puts the cat amongst the pigeons, talk about bad timing on that £ cover lol. As you say, the market has heavily priced in US weakness, further QE etc, and today's data is suggesting maybe it's all wrong. If tomorrow's data also shows strength, watch out below in anti-dollar plays, they have had a big runup and some hot money is definitely in there, it could start something of a correction over the next week or so. Risk has shot up for currencies and gold, at the very least, so I'm taking off some of the gold, hedging the rest with some short-term options, and edging back into that pound short on small size (I actually have on long Yen too so de facto I am long Yen/GBP on part of my position - agree this is a safer and purer play). I'll wait and see how today closes, and then check the reaction to the figures tomorrow before doing more, if they confirm more US economic strength and the market responds with a vigorous dollar rally, then I'll put on some more dollar longs if it goes my way. Overall I'd say short GBP against Yen looks good, and short GBP vs $ may look good too if this move is the beginning of something.
For now though, I think the easy money in the dollar short/gold long has been made for the moment. Long-term I still like gold but it's vulnerable here and worth at least hedging with some puts, scaling back to core size, and taking more aggressive positions off the table IMO. If I'm wrong then the obvious signal would be if gold recovers its losses and closes higher on the day, that would signal underlying strength and I'd have to reconsider. Today and tomorrow's session could see some interesting action.
