Most investors assume the greatest threat to their portfolio is a bad market, a poorly chosen fund, or a manager who underperforms. Michael Gold, founder and CEO of Gold Family Wealth in Westport, Connecticut, says the actual answer is simpler and far harder to protect against.
“The greatest determining factor of being successful when it comes to investing has very very little to do with your underlying investments,” Gold says in a behavioral finance video. “It really comes down to your behavior, how you act, how you react.”
The numbers support that view. DALBAR’s 2024 Quantitative Analysis of Investor Behavior found that the average equity investor earned 16.54% in 2024, compared to the S&P 500’s 25.05% return, a gap of 848 basis points attributed almost entirely to poorly timed moves in and out of markets. The firm’s “Guess Right Ratio,” tracking how often investors correctly time their entries and exits, fell to just 25% that year. Three out of four timing decisions were made at the wrong moment.
This behavioral gap has been documented across decades and market cycles. It costs investors far more than any management fee or tax drag. No allocation model can hedge it, because the risk is the person holding the portfolio.
When Behavior Undoes a Sound Plan
Gold tells a story he returns to often. At a birthday party in 2010, he ran into his friend’s father-in-law, a man he’d met years earlier at a wedding. The man looked hollowed out, nothing like Gold remembered. He’d sold his business around 2005 for just over $5 million, enough to retire comfortably with his wife.
Then the 2008 financial crisis arrived. Each month’s statement was worse than the last. “Every time I turn on the news, Jim Cramer was saying the world’s coming to an end,” the man told Gold. “CNBC, the financial media, everybody’s saying the Dow’s going to 2000 and it’s a financial apocalypse.” By December 2008, roughly half his portfolio had been lost. He sold. Not quite at the March 2009 bottom, but close enough. By 2010, the market had largely recovered while he remained in cash, around 70 years old, with insufficient assets to cover his lifestyle without working part-time. The S&P 500 went on to gain roughly 400% from its March 2009 low before the pandemic.
The man’s investment structure was reviewed by Gold a week or two later. It was sound. “It was actually pretty sound and you’d probably be in pretty good shape right now,” Gold told him. “His behavior did him in. His investment structure, was it the greatest in the world? No. But it was fine. It was going to achieve what he needed to achieve.” The loss of his retirement security, Gold says, was preventable. “That is something that could and should have been saved.”
The reason it wasn’t came down to one thing: “He didn’t really have the right team around him that was guiding him that have been through these types of environments before.”
The Advisor as Behavioral Coach
The cognitive biases Gold describes are universal human vulnerabilities, not individual weaknesses. “We all have these biases,” he says. Fear at peak volatility reliably crowds out the evidence accumulated over years. That’s exactly why behavioral coaching has to be considered a core advisory function, not a soft-skill bonus.
This shapes how Gold runs his Westport-based practice. When his investment team suggested adding gold to client portfolios because clients had seen favorable coverage on the news, Gold’s answer was immediate. “That’s a hard no,” he told them. “Our job from the investment standpoint [is] to invest accordingly based on whatever outcomes or results that they need.” Responding to emotion rather than analysis, in his view, is an abdication of advisory responsibility.
The clinical parallel Gold draws is direct. A surgeon who performed three of his spinal procedures never once asked what Gold had seen covered on television. “Before they did anything, they did a suite of tests, MRI’s, CAT scans, X-rays and all that. And then they laid out all the options from conservative to aggressive.” Diagnosis precedes prescription. Recovery requires guidance. “There is a big psychological component to it,” Gold says.
The S&P 500’s 34% decline in March 2020 recovered to new highs by August of that year. Investors who sold during those weeks locked in losses that patient investors were never required to absorb. Only 25% of historical market corrections have turned into full bear markets, according to Carson Wealth research. Evidence consistently favors staying the course. Human psychology consistently pressures investors toward the opposite.
For Michael Gold, the advisor who builds a sound portfolio and then leaves clients alone to manage their own fear hasn’t finished the job. “When you have the right team around you,” Gold says, “there’s also the behavioral element, that bedside manner of coaching and consulting you through those really tough times.”
