The Geraldine Weiss dividend yield theory applied to M&G Plc ($MNG) uses the stock's historical dividend yield range to estimate when the price is cheap or expensive relative to its own dividend-paying history (2020–2026). Based on that history, $MNG is currently trading in overvalued territory.

When the $MNG yield climbs above 🟢 16.07%, the stock has historically been undervalued. When the yield falls below 🔴 5.61%, M&G Plc has historically been overvalued. The dashed 🟡 fair value (~10.84%) line marks the orientative midpoint between both extremes, not a price target.
