Here's why 'dead' investors outperform the living

cnbc.com:

«Dead» investors often beat the living — at least, when it comes to investment returns.

A «dead» investor refers to an inactive trader who adopts a "buy and hold" investment strategy. This often leads to better returns than active trading, which generally incurs higher costs and taxes and stems from impulsive, emotional decision-making, experts said.

Doing nothing, it turns out, generally yields better results for the average investor than taking a more active role in one's portfolio, according to investment experts.

The «biggest threat» to investor returns is human behavior, not government policy or company actions, said Brad Klontz, a certified financial planner and financial psychologist.

«It's them selling [investments] when they're in a panic state, and conversely, buying when they're all excited,» said Klontz, the managing principal of YMW Advisors in Boulder, Colorado, and a member of CNBC's Advisor Council.

«We are our own worst enemy, and it's why dead investors outperform the living,» he said.

Dead investors continue to «own» their stocks through ups and downs.

Historically, stocks have always recovered after a downturn — and have gone on to reach new heights every single time, Klontz said.

Data shows how detrimental bad habits can be relative to the buy-and-hold investor.

The average stock investor's return lagged the S&P 500 stock index by 5.5 percentage points in 2023, according to DALBAR, which conducts an annual investor behavior study. (The average investor earned about 21% while the S&P 500 returned 26%, DALBAR said.)

The theme plays out over longer time horizons, too.

The average U.S. mutual fund and exchange-traded fund investor earned 6.3% per year during the decade from 2014 to 2023, according to
