Investment Strategy

Muhlenkamp & Co Inc seeks to maximize total after-tax returns through capital appreciation and income from dividends and interest, consistent with reasonable risk. The investment strategy focuses on investing in undervalued assets identified via a bottom-up process emphasizing return on equity and fundamental valuation. Positions may include equities of U.S. companies the firm believes are materially undervalued by the market, and bonds as appropriate. The firm adheres to a disciplined approach, seeking opportunities independently of prevailing market fads, and emphasizes risk reduction through protecting purchasing power over the long term rather than just short-term price volatility.
