Putnam Research Fund (PNRAX) Sharpe Ratio: 2.37

Mutual Fund · Currency in USD · Last updated Jun 10, 2026

The fund invests mainly in common stocks (growth or value stocks or both) of large U.S. companies that the managers believe have favorable investment potential. For example, the manager may purchase stocks of companies with stock prices that reflect a value lower than that which the managers place on the company. The manager may also consider other factors that the managers believe will cause the stock price to rise.

PNRAX's Sharpe Ratio of 2.37 indicates that for each unit of volatility, it generates 2.37 units of excess return above the risk-free rate. The ratio is calculated using historical daily returns over the past 12 months (as of Jun 10, 2026).

Sharpe uses total volatility (standard deviation) which includes both upside and downside price movements, making it useful for comparing risk-adjusted returns across different assets.
