Principal Funds received two 2011 Lipper Fund Awards for consistent multi-year performance for the Principal MidCap Blend Fund; Institutional (PCBIX). The fund was named the best multi-cap core fund for the five-year period and 10-year period. Principal Global Investors portfolio manager Bill Nolin and team run the $2.2 billion fund. The team generates in-depth, original fundamental research and uses a risk-reduction process in selecting individual stocks. “We’re long-term investors, so we’re focused on selecting high-quality companies with sustainable competitive advantages,” Nolin said. “That strategy has served us well in all types of markets.” Lipper, a leading global research firm, presented the awards at a March 8 ceremony in New York City. The Lipper Fund Awards are part of the Thomson Reuters Awards for Excellence, a global family of awards that celebrate exceptional performance throughout the professional investment community. “This is a testament to the disciplined investing by Bill and team from the very beginning,” said Nora Everett, president and CEO of Principal Funds. “Principal Funds is honored to be recognized for our long-term focused, risk-astute investment management capabilities.” A new white paper, available here, examines why investors should consider an allocation to mid-cap equities and provides insights into the investment process and philosophy of the portfolio management team.
