TT,
I can't believe many things SEA related these days.
While the "energy sell-off" is not SEA specific the severity of the sell is"redomicile specific" IMO.
Consider this chart, comparing SEA an ASX listed E&P with operations only in the USA, with 2 other ASX listed E&P with operations only in the USA (i.e. OEL and BYE).
Chart begins the day before the announcement. The quick rise a couple of days later is the weekend of the drone attack on Saudis.
So SEA falls 46% and OEL & BYE fall about the same at 15% ... that a 200% greater fall (if I wanted to choose a dramatic relative measure).
