Homebuilding-related stocks were slaughtered Tuesday amid more dismal news about the state of the U.S. housing market.
The latest bleakness came from builder material supplier
, which slid 6.7% after posting a big drop in second-quarter earnings and saying "the housing recession is entering the second year of what is likely to be a multiyear downturn."
also spooked investors by saying
defaults are rising across all mortgage categories. Shares of the lender tumbled 10.5% to $30.50.
After the market closed, homebuilder
reported a worse-than-expected loss for the quarter because of hefty land impairment charges.
Nearly every homebuilder stock closed at a fresh 52-week low Tuesday. Some of the most heavily shorted stocks got killed, proving that the possibility of looming short squeeze is not a good reason to invest in the sector, despite what some market watchers have suggested in recent months.

After the bell, Centex reported a loss from continuing operations of $131 million, or $1.08 a share, compared with profit of $172 million, or $1.37 a share, a year earlier.
The Dallas-based company's results were dragged down by $193 million of land impairment charges related to housing communities that can no longer be sold at a profit.
Analysts -- who usually build these charges into their estimates -- expected a loss of 16 cents a share, according to Thomson Financial.
Earlier, USG posted second-quarter earnings that missed analyst estimates because of sharp price cuts in its Sheetrock-branded wallboard, which is a major material used in new-home construction.
USG reported earnings of $56 million, or 56 cents a share, down from $176 million, or $3.03 a share, a year earlier. Analysts expected 65 cents per share of profit, according to Thomson Financial.
Sheetrock prices fell 14% in the quarter, which likely stemmed from the company's desire to keep plants running despite lower demand, Bank of America analyst Daniel Oppenheim wrote in a research note Tuesday.
