Shares of First Solar (NASDAQ:FSLR) moved upward today, after the company raised guidance and announced a partnership with General Electric. Conversely, SolarCity (NASDAQ:SCTY) fell on the news. KB Home (NYSE:KBH) is also up today, after announcing that revenue and net income were up for the quarter, the first quarterly profit since the housing meltdown. Oracle (NYSE:ORCL) fell today, after missing analysts' expectations for the fourth quarter, possibly because of growing pressure from younger, more nimble competition. And WisdomTree Investments (NASDAQ:WETF) took a hit today, after a Citigroup analyst downgraded the ETF maker to "sell."
