JrKob mentioned downtrends and ;
while we are in mostly uptrends long spanish stocks could be an advantage.
Frankly dont care much shorting strong/long stuff, like homebuilders, and that is a personal decision;
like to find something like INTC sector, with historical weakness.
You can see on a 1 year candle chart,INTC has had a some good downtrends; including a good polar bear gap last July.
And that polar bear gap down could happen to any swingtrader;
however and while INTC is now uptrending again,
that downtrend gap happened to a historical weak sector stock.
And have ''Intel inside'' my computer, they are a fine company;
hard to buck a weak sector all the time,and they sold it for several more days after the down gap.
