Low volume pump, high volume dump

I have a question about market volume. So back on Friday, February 6th, we had a +2% day on SPY. The volume that day was about half the 10-day average volume.

Today we're getting a decent pump on SPY (almost +1% right now). The volume right now is 29 million, and the day is only half over, but the 10-day average volume is 90 million. So I think today will end up being another low volume pump day.

Does the market normally pump on low volume days and dump on high volume days? I'm not sure if I see a pattern or if this is just my confirmation bias. Thanks!
