RE:RE:loaded the truck at $8.17$.37 loss in four days isn't that bad. Two week before that and it would have been a $2 loss in 15 trading days. Pity the poor fool who bought at $13.87 on May 5. That's a $5 loss if you held.
36% loss in 2.5 months.
It would be even worse if you bought under $9 rode it up and then back down to now what would be a loss. Trailing stops are the only way to play an uptrend.
In this oil market COS may never get back to those highs. There could be serious psychological damage done here and a lot of overhead higher than here.
