Gazing Into the Mirrors of Time

A sharp rotation occurred in the first half of 2022 as investor worries pertaining to more persistent elevated inflation, aggressive Federal Reserve policy and a backdrop of higher interest rates generally prompted investor migration away from durable growth companies towards names with greater visibility of near-term profitability. During this period, the Harbor Capital Appreciation Fund’s disciplined focus on companies with multi-year structural growth opportunities faced meaningful headwinds on an absolute and benchmark-relative basis.

Within this more challenging environment, concerns surrounding the future performance potential for companies with long-term growth opportunities increased causing many investors to question their growth equity allocations. Consistent with its history, the Fund’s investment team at Jennison Associates maintained conviction in their time-tested approach and emphasis on companies with sustainable competitive advantages and long-term earnings expansion potential.

Patient Harbor Capital Appreciation Fund investors have been rewarded thus far in 2023 given the tailwinds of moderating inflation, a general level setting of interest rate expectations, and the Fund’s ability to source durable growth amidst a general scarcity of earnings expansion across the broader market. Per the chart below, Harbor Capital Appreciation’s year-to-date cumulative return and excess return (versus the Russell 1000 Growth Index) through June 20th have proven almost mirror opposite relative to 2022 results through the same day last year.

The Fund’s investment team does not attempt to time markets based on short-term shifts and believes that strong growth of earnings should ultimately drive performance over long-term horizons. This longterm approach has resulted in general fluctuation of the Fund’s rolling 1-year peer rankings between Morningstar’s Large Growth category’s top and bottom quartiles as its investment style has come in and out of favor with prevailing market conditions (please refer to the chart below).

Importantly, given Jennison’s proficiency in identifying companies with potential long-term growth, the Fund’s rolling 10YR rankings have consistently placed within the top third of its large growth peer group over the period.

Overall, we believe that investors consider the mirrors of time looking ahead. History has shown that looking through shorter-term periods marked by uncertainty has led to longer-term more favorable results for the Harbor Capital Appreciation Fund.
