When the $TDG yield climbs above 🟢 25.43%, the stock has historically been undervalued. When the yield falls below 🔴 2.02%, Transdigm Group Incorporated has historically been overvalued. The dashed 🟡 fair value (~13.72%) line marks the orientative midpoint between both extremes, not a price target.
