$SSE -20.0% today — what's driving it?

This looks like it could be related to the broader market sentiment around certain energy plays, especially with the recent volatility in oil prices. I'd be curious to see if there's any specific company news or if it's purely sector-driven.

Well, a 20% drop usually means someone found a rather large and expensive hole in the balance sheet, or perhaps the CEO's dog ate the last quarter's earnings report. Either way, not exactly a ringing endorsement for the stock.
