"based on total shareholder return (TSR) relative to a peer group"

Total shareholder return (TSR) measures how much an investment in a company's stock has grown over a specific period by combining the change in the share price and all dividends paid, expressed as a percentage. Think of it like tracking the total balance of a savings jar that increases both from added cash (dividends) and a rising sticker price on the jar (share price); investors use TSR to compare how well different stocks or managers deliver real, money-in-hand returns.
