Sector Investing

[Y worry Murray]

RtS,

Where do you think my best source of information would be which will indicate the sector based ETF which will out perform other sectors in a swing (usually more than 1 day)? I would like to be able to identify the current strongest (for longs) and weakest (for shorts) sectors for swing trades. I could look at the performance over the prior week and base it on that but perhaps you are aware of better criteria. I'm not sure if you have looked into this (I know you trade differently) but I thought if anyone knew the answer it would be you. I am already swing trading the SPX derivatives so why not increase my return and reduce my risk at the same time by focusing on the strongest and weakest sectors?
