The Geraldine Weiss dividend yield theory applied to Main Street Capital Corporation ($MAIN) uses the stock's historical dividend yield range to estimate when the price is cheap or expensive relative to its own dividend-paying history (2016–2026). Based on that history, $MAIN is currently trading close to its fair value.

When the $MAIN yield climbs above 🟢 15.55%, the stock has historically been undervalued. When the yield falls below 🔴 4.57%, Main Street Capital Corporation has historically been overvalued. The dashed 🟡 fair value (~10.06%) line marks the orientative midpoint between both extremes, not a price target.
