Is it true that if the value of a share goes below what a shareholder paid for it the shareholder makes money.?

No, it is not true that a shareholder makes money if the value of a share drops below the price they paid for it. When the share price falls below the purchase price, the shareholder incurs a loss on their investment. Profit is realized only when shares are sold for more than the purchase price, regardless of any temporary fluctuations in value.
