"They believed you can't mix rock, country, and rap, and that crossover is dead. I always knew it would work. And it will always work as long as you're really into it and like what you're doing." -- Kid RockNEW YORK ( TheStreet) -- It has been a strong start to 2013, with the S&P 500 ( SPY) up nearly 4% thus far in January. Risk-on has certainly been the right call exiting last year and entering this one despite the fiscal cliff noise and continued fears over another collapse in equities. Our ATAC models used for managing our mutual fund and separate accounts have stayed long stocks since late-November, and there are no near-term signs of intermarket deterioration just yet to warrant concern. This has become less of a risk-on/risk-off environment, and more of a risk rotation one. Within that risk rotation appears to be an eclectic group of winners and losers. Every week I run a screen on the over 1000 ETFs/ETNs I track to identify those areas of the investable landscape which are exhibiting extreme price behavior relative to their own respective 20 day moving averages. The idea is to see if there is a message happening beneath the surface of the market by looking at the opposite ends of winners and losers spectrum over a rolling 1 month period. Take a look below for the latest results.
