What's with this carryback BS that will allow homebuilders to offset current and future losses with previous years' profits? (And I read it isn't just for homebuilders, it's for all companies apparently -- http://www.washingtonpost.com/wp-dyn/content/article/2008/04/03/AR2008040304026_pf.html) Did the homebuilders get that because a couple of months ago they declared they were going to halt all congressional campaign funding because they didn't think the govt was doing enough to help out with the housing crisis? (http://www.reuters.com/article/politicsNews/idUSN1227547320080213) Can I get the carryback too? I had a large profit from stock sales last year. But this year I have a large loss, and would like to offset that loss with last year's profit. Can I do that?
