There are so many great companies in the market today, but there are also many overvalued companies. By using the ModernGraham Valuation Model, I've selected the five most overvalued Dow Components reviewed by ModernGraham according to the ModernGraham approach. Defensive Investors are defined as investors who are not able or willing to do substantial research into individual investments, and therefore need to select only the companies that present the least amount of risk. Enterprising Investors, on the other hand, are able to do substantial research and can select companies that present a moderate (though still low) amount of risk. Each company suitable for the Defensive Investor is also suitable for Enterprising Investors.  Only speculators should pursue companies not suitable for either the Defensive Investor or the Enterprising Investor.

Merck & Company (MRK)

Merck & Company does not qualify for either the Defensive Investor or the Enterprising Investor. The Defensive Investor is concerned by the low current ratio, lack of earnings growth over the last ten years along with the high PEmg and PB ratios. The Enterprising Investor is similarly concerned by the lack of earnings growth over the last five years along with the high level of debt relative to the net current assets. As a result, value investors following the ModernGraham approach based on Benjamin Graham's methods should explore other opportunities at this time. From a valuation side of things,  the company appears to be overvalued after seeing its EPSmg (normalized earnings) drop from $2.66 in 2010 to only an estimated $2.23 for 2014. This demonstrated lack of growth clearly does not support the market's implied estimate of 9.01% earnings growth and leads the ModernGraham valuation model, based on Benjamin Graham's formula, to return an estimate of intrinsic value well below the price.  (See the full valuation)
