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 life insurance provider FBL Financial Group (NYSE: FFG) jumped as much as 12.2% in a very short-lived, low-volume rally overnight.

So what: Yesterday, FBL Financial announced that Chairman Craig Lang has resigned from the board, replaced by Iowa Farm Bureau Federation President Craig Hill. The double-digit spike was very, very brief, but share prices retreated to a still-respectable 2% gain on an otherwise very gloomy market morning.

Now what: So it's a tale of two Craigs. Hill has been on FBL's board since 2007, but stepped into the FBL sphere of operations way back in 1989 -- yes, the Iowa Farm Bureau Federation is closely tied to FBL Group. Lang lost some board support by pushing unpopular policies as a member of the Iowa Board of Regents in recent years; investors seem happy about the switch.

If you're into FBL for the sake of its modest dividend, this leadership change won't make a difference. You might want to consider more generous payers in the regional life insurance sector, such as Symetra Financial (NYSE: SYA) or Protective Life (NYSE: PL), though.
