Of course stocks moved based on supply/demand, but there are drivers and catalysts which bring the marginal buyer/seller out to play. So I don't think saying that stocks moved based on supply/demand is adding anything really. If you're suggesting that all equities price changes are meaningless, that is simply not the case. If you're not suggesting that, my apologies, but the way you phrased it reminds me of something I often hear which seems to be a popular misunderstanding (and embraced in much of academia).
