"A footnote states that the transaction resulted in short sales"
Short sales are trades where an investor borrows shares and sells them immediately, aiming to buy them back later at a lower price and return them to the lender; the profit is the difference if the price falls. This matters to investors because short selling can signal negative expectations about a company, add downward pressure on a stock’s price, and carries unlimited loss risk if the stock rises instead of falls—like betting a borrowed item will be cheaper to replace later.
