Thank you! So each exchange has its own formula for determining the price that gets shown on the ticker? Let's say someone owns shares in a very low-volume stock — one that gets a couple trades a day, at most. Could they artificially increase the share price by offering their shares at a high price, then using a second account under their control to immediately buy them at the inflated price?
