PRIMECAP Management Investing Philosophy
PRIMECAP looks for stocks that will outperform the market over a three to five-year horizon. The firm strives to recognize values early and patiently wait for the market to reach a similar conclusion. Often, PRIMECAP's search begins with companies and industries that are currently out of favor among investors and, thus, the firm's investment ideas are frequently early. Despite this, conviction derived through the firm's research efforts gives it the fortitude to stay the course when the near-term fundamentals are challenging, even if the firm believes the long-term thesis is intact.
