Quick Take: A middle-of-the-road growth strategy that is considerate of stock valuations suits Bert Boksen, manager of Heritage Aggressive Growth Fund/A (HAGAX). Asked about the fund’s strong returns, Boksen said: “We diversify the portfolio, and try not to hit home runs.”

The fund’s long-term record is competitive. For the five-year period through last year, Heritage Aggressive Growth rose 12.1%, on average, versus 3.1% for its mid-cap growth peers. It is in the top quartile for four out of the past five years. Lower expenses help the fund’s overall returns. The portfolio charges 1.48% of assets, versus 1.81% for the peer group.

Boksen, the fund’s manager since its inception in 1999, looks for companies growing earnings 20% or more. He follows a broadly diversified strategy and limits sector overweightings and underweightings. However, he focuses on certain industries, such as gaming and energy currently, where he finds attractive companies.

To help lessen volatility, Boksen keeps a market weighting in technology. The fund’s three-year standard deviation shows its volatility is in the mainstream of mid-cap growth funds.
