SKPETRO - narrow escape

It was pure luck that my SKPETRO order did not match the other day when it dropped. I DID NOT realise that it's financial results would be announced the next day -- and it suffers substantial loses!

From the chart, I cant see sign of rebound although 20MA just crossed 200MA.. it may just turn around... and the next support level is around 1.76.. unless of course, crude oil rebounds sharply... 

Narrow escape from being stuck in this stock... as if im not stuck enough... phew...
So...
What is the lesson learnt?

• There is always a reason why a share drops or goes up suddenly - check the date of the release of their quarterly report!!
