That was what I usually would say.

But in this case, I don't think so, especially involved in UBS, and the short positions were increased sharply over last month.

Short positions on 1 February 1.48m
Short positions on 19 February 4.5m (Share price: $2.63)

Sharp increase in short positions had definitely huge effects on the share price, especially involved in UBS shorting.

One does not fit All, imo.
