I don't know if todays 6% market change is one having to do with insider knowledge of what is to come soon or its mere speculation. Volatility has been characteristic of this stock recently, not unusual to see 20% swings within a few days. I think odds are 3:1 or better dividend is maintained. It isn't unusual to see this level of volatility in low priced high dividend payers, often the subject of dividend cut speculation, on shares like this.
Nothing specific to PWE. Many other oil stocks, especially Canadian, had a bad day. Brent was down today and WTI was up only slightly despite DJI having a big day. XOM, BP, PGH, ERF, BTE all had a reversal to the downside and closed in the minus territory. With yesterday's run up PWE just could not hold the gains today and when profit taking started it got out of hand. Just a bad day in the oil patch today.
