Is shareholder wealth measured by the book value or compound value or historic value or market value of the shareholders' common stock holdings?

Shareholder wealth is primarily measured by the market value of shareholders' common stock holdings. This reflects the current price at which shares can be bought or sold in the market, capturing investors' perceptions of the company's future performance. In contrast, book value and historic value are based on accounting measures and past performance, which may not accurately represent current investor sentiment or potential growth. Therefore, market value is the most relevant metric for assessing shareholder wealth.
