Completely possible if you understand how it is calculated. Which it would seem you don't from your last sentence.

A share is considered a buy if the transaction occurs at a higher price than the previous transaction. It's a sell if it's lower than the previous. "Slapping the ask" or "dumping into the bid" has nothing to do with it.

What does matter is higher volume, as you pointed out, which means the bid/ask is jumping around a lot faster. And the fact that buyers are bargain hunting and sellers have more ammo. Sellers can be selling in smaller blocks than buyers and still push the price down. Especially when they are Algo traders and can stack ask and adjust prices faster because of program trading.
