Assuming that you are talking about companies on stock exchange, their price is determined by the market buy and sell activities. Also share price is not an indicator for companies well being. .
Except for the IPO and subsequent offerings, the company does not determine the share price. The market does.
If the share price falls, the market believes the shares are worth less than they were before the drop. Or, there are more sellers than buyers. Or, the overall market is down. Or...who knows?
A company has NO say on the price of its share after its IPO, the market factors determine (Demand & Supply )
price of a stock depends on supply and demand
google stock started at $10, now in high demand, over $500
They don't.
Investors who want to buy or sell shares are who "determine the price", by bidding a buy price or asking a sell price....
Does it mean the company is doing badly if share price falls because they're trying to entice more investors?
