Expansion on title: how do stocks move up in terms of how much money flowing in?
If a 10Billion market cap company moves 10% today, does it actually mean 1 billion dollars of money bought up the stock?
If yes and it means the same for a smaller market company, that would mean smaller market cap companies require less volume/money to move same amount of percentage points right?
(or is stock movement simply just about the current demand/supply of liquid shares trading)
