Although we don't believe in timing the market or panicking over market movements, we do like to keep an eye on big changes -- just in case they're material to our investing thesis.

What: Shares of Chinese solar player LDK Solar (NYSE: LDK) are enjoying time in the sun today, rising by as much as 10%, fueled by buyout speculation within the sector.

So what: Bloomberg reports that domestic rival First Solar (Nasdaq: FSLR) has become so cheap recently that it could be a potential acquisition target. This notion is one that fellow Fool Travis Hoium has discussed, even as recently as yesterday.

Now what: Possible suitors could include General Electric (NYSE: GE) or Siemens (NYSE: SI), and would be seen as a boon for the solar sector. LDK and other Chinese players use polysilicon, whereas First Solar uses cadmium tellluride in its panels. Other companies like Suntech Power (NYSE: STP) and JA Solar (Nasdaq: JASO) are also enjoying gains today. The industry has been ravaged by plummeting prices and rampant competition, so some acquisition activity could help give it a much-needed boost.
