That is 100% true, but was everyone expecting it to fall from $4 to $1 back Dec 2020. No one knows the direction but we can use gaps as a measure of probability what might happen. If the likelihood of the gap will be filled would it not be wiser if you are looking for an entry to wait at least 10 days to see what happens, this could avoid you jumping in too early or depending on when you enter you're picking up more shares for the same price.

I'm in PNV for the long haul, if I can use these movements to increase the probability of picking up more shares at the same price then over the long term I'll be in a much healthy position.

Then again maybe PNV has just fallen back to its normal trend line and will bounce from here or it could keep falling further.
