You may not see the daytraders leaving other stocks, even though they are. That is because, depending on what the particular stock is doing, it may be hidden by the actions of the investors  or the swing traders.

Even now, there is a bit of a sell-off on V.DDN ( for example only, I don't own any) but  the investors are still fighting to get in, thinking it will go higher in the days/weeks to come.

I'm no expert, but often times when a stock runs into the close, it gaps down in the morning, at least to its more sedate trendline.

Because NOT has been so quiet of late, all the short term traders /shorters want their money off the table so they can sleep at night.

Hope this helps.
