What is packaged as a positive function
Price discovery and bubble prevention: When stock prices are overvalued relative to a company's true value, short selling adjusts stock prices to appropriate levels and prevents asset bubbles from forming.
Market liquidity provision: By lending and selling stocks, it increases trading volume and helps activate trading in the entire stock market.
Risk hedging and profit opportunities in declining markets: When the value of stocks held by investors falls, short selling can offset (hedge) losses, and it provides investment opportunities even in declining markets.
Market efficiency and transparency improvement: By ensuring negative information is quickly reflected in prices, it reduces information asymmetry in the entire market and increases efficiency.
