Of course you never know what will happens tomorrow, but normally a drop like this doesn't creates the ultimate bottom. Most logical patern is a share price that's drifts lower in the coming weeks or even months.
A new announcement can bring back some life in SDL but if this announcement doesn't brings the news people are hoping for it will cause another run to the exit.
(I have no interest in buying SDL, SDL is too big in MC for my portfolio)
