Case Study in Dividends Consumed by Tornadoes

Joplin-based electricity (and other utilities) provider Empire District (EDE) plunged today as it suspended its dividend.  I share this as a lesson in investing, as there are many.  First, the news today is several days after the tornadoes - might some quick thinking have led to more selling than the stock initially saw (23ish peak to 22.5ish before the plunge today)?  Second, investing in smaller companies (market cap was about $900mm) that aren't very diversified entails extra risk - be aware.  Third, is the stock really worth 15% less?  Investors were enjoying about 5.7% dividend yield, so today's action seems to imply about three years of no dividends.  The company stated that the suspension is only 2 quarters.  On the surface, this sure seems like a bargain.  That's the third lesson - sellers (and buyers) aren't always so rational.
