Index investing pioneer Charley Ellis says what gave rise to the success of the index fund remains true today: “It’s virtually impossible to beat the market,” he told CNBC’s Bob Pisani on last Monday’s “ETF Edge.”
But Ellis warns of another hurdle just as high as active management’s long-term underperformance that holds back many investors: You might be your own worst enemy when it comes to your investment strategy.
The market’s complexities, volatility and an infinite number of other variables can cause unpredictable price fluctuations, but your own mindset is just as key among the variables that can set your financial portfolio back.
In his new book, “Rethinking Investing,” Ellis details a slew of unconscious biases that impact our thinking about money in the market. A few of the big ones he addresses in the book:
The gambler’s fallacy: The belief that because you were right picking one stock, you will be right picking all other stocks.
Confirmation bias: Seeking information that confirms pre-existing beliefs.
Herd mentality: Blindly following actions of a larger group.
Sunk cost fallacy: Continuing to invest in failing investments.
Availability: Being influenced by easily accessible information, whether it is actually valuable or not.
The impacts of these biases on your portfolio strategy can be major, Ellis says, and should lead investors to “rethink” their approach to the market.
“Instead of trying to get more, try to pay less,” he said. “That’s why ETFs … have made such great sense.”
Ellis argues that use of lower fee funds, combined with letting go of our behavioral biases, can help investors win years, or even decades, later.
“They’re boring, so we leave them alone, and they do work out over the long run, very, very handsomely,” he said.
Long-time ETF expert Dave Nadig, who appeared on “ETF Edge” with Ellis, agreed.
“People trying to predict people always works out terribly,” Nadig said. A long-term investment in an index fund “helps you overcome an enormous number of these biases simply because you’ll pay less attention to it,” he added.
He also pointed to the mistake many investors make of trying to beat the market by timing it, only to end up outsmarting themselves. “There are more good days than bad days,” Nadig said. “If you’re missing the 10 best days in the market and you missed the worst 10 days in the market, you’re still much worse off than if you just stayed invested. The math on that’s pretty hard to argue with.”

The Treasury Department has set a new deadline of March 21 for millions of businesses to fulfill a new reporting requirement on “beneficial ownership information,” after a court order allowed the federal agency to start enforcing the measure.
The Corporate Transparency Act, which Congress enacted in 2021, requires small businesses to disclose the identity of people who directly or indirectly own or control the company. The measure aims to prevent criminals from hiding illicit activity conducted through shell companies or opaque ownership structures, according to the Treasury.
Businesses have suffered a degree of whiplash from the on-again-off-again deadlines to file BOI reports. A string of court orders had prevented the Treasury from enforcing the measure, only to then see courts strike down those rulings.
The U.S. District Court for the Eastern District of Texas on Feb. 18 lifted a nationwide injunction that had prevented the Financial Crimes Enforcement Network, known as FinCEN, which is part of the Treasury, from enforcing the Corporate Transparency Act.
Room for more delays?
The BOI reporting measure applies to about 32.6 million businesses, including certain corporations, limited liability companies and others, according to federal estimates.
Businesses and owners that don’t comply with reporting rules are potentially subject to civil penalties of up to $591 a day, adjusted for inflation. They could also face up to $10,000 in criminal fines and up to two years in prison.
FinCEN left the possibility of further delays on the table even as it extended its previous reporting deadline by 30 days.
“FinCEN will provide an update before then of any further modification of this deadline, recognizing that reporting companies may need additional time to comply with their BOI reporting obligations once this update is provided,” according to a Feb. 18 FinCEN notice.
FinCEN also said it would prioritize enforcement for businesses that “pose the most significant national security risks.”
