Shares of San Jose, Calif.-based SiRF Technology (SIRF - Cramer's Take - Stockpickr) continued Monday's evening's after-hours wipeout, losing more than half their value Tuesday to $7.36 on disappointing fourth-quarter results. This morning, the maker of semiconductor and software products was further hammered as Jeffries, Lehman Brothers, Soleil, Oppenheimer, FTN Midwest, Longbow and RBC Captial Markets downgraded the stock.
Navigational devices maker Garmin(GRMN - Cramer's Take - Stockpickr) fell $5.88, or 8.4%, to $63.78 as analysts feared SiRF's weak results could mean lower demand for GPS devices in the next few months.
