I don't think that's a very relevant calculation. Or at least you haven't articulated why. It's just a measure of liquidity. A stock can trade 1$ or 0$ per day

I don't think that's a very relevant calculation. Or at least you haven't articulated why. It's just a measure of liquidity. A stock can trade 1$ or 0$ per day and still have a market cap of 300B ( see private eq.) (Maybe you are onto something, if stock iliquid, they got stocks at 0. If stock very liquid they got stocks at actual price.)
