The Yacktman Fund's Donald Yacktman, the mutual-fund manager with the best record in the past 10 years, has boosted his holdings in out-of-favor stocks, including scandal-plagued media giant News Corp. and troubled computer-networking bellwether Cisco Systems .

The manager of the $5.4 billion fund also initiated a big position in Research In Motion , maker of the beleaguered BlackBerry smartphone, and added to a stake in Hewlett Packard , both of which have seen their shares slide this year. Yacktman made the changes in the second quarter, according to information from Morningstar and Bloomberg.
