Equities have surged for years, and especially so for the past 12 months, so clients may be overly focused on returns at the expense of risk. That might be understandable on the part of investors, but not permissible for their advisors.

Indeed, the S&P 500 has posted an impressive 13.8% annualized gain for the past five years, as measured by the biggest ETF that tracks the benchmark index (SPY). Over the past year, it’s even better at 16.8%.

But underlying those impressive returns — the part too often ignored by clients — is a level of risk that can creep up to an unwarranted level for the corresponding returns.

The Sharpe Ratio helps illustrate whether a high return was the result of excess risk taking compared to similar funds, says Tom Roseen, head of research services at Lipper. “The best fund is not necessarily the one with the highest return, but the one with the most superior risk-adjusted return,” he says.

“Historically, some folks would say a Sharpe of 2 or greater is what was needed,” he adds. “However, I look at Sharpe as a ranking tool.”

Greg McBride, chief financial analyst at Bankrate, illustrates this idea with a story that any client can relate to. “It’s one thing to get to the airport in time for your flight, but what did it take to get there? Was it a white-knuckle ride weaving in and out of traffic, or a leisurely, low-stress ride with plenty of time to spare? The ride that gets you to the airport without the stress is the one with the higher Sharpe Ratio.”

So in the name of metaphorical low-stress rides to the airport — i.e., returns without the volatility — we collected the mutual funds and ETFs with the best risk-adjusted returns.
