Just last week, one of those Fools, All-Star TerryHogan, succinctly summed up the KRS bear case for our community:

I would be hard pressed to think of a worse investment. I'm not super keen on the regional banks, because some are going to suffer at the hands of the behemoths. But others are going to get bought out, and still others are going to thrive and grow after the shakeout of the past 6 years. Most of them also have a decent yield. I also think inverse ETFs stink.
