Why would you say that. The entire market is weak today and UGU is down by around the same amount. The only way I can see you saying that is if you bought at the $33 high earlier this year, and expect to get your principal back quickly.
If you bought at in the high 20s, you should be fine collecting the nice divvys for the foreseeable future. They just declared the 56cents divvy 3 weeks ago, so business appears to be stable.
