Question:

When I valued Reckitt Benckiser using the valuation model, the DFC and RIVM valuations were higher than the current stock price. The DDM valuation, on the other hand, is lower than the current price.
The current market price is 62 pounds and my DDM valuation is 58, my DCF valuation is 90 and my RIVM valuation is 82. Shouldn't all three models indicate an over-valuation over an under-valuatio?
