Investing myths 2025 are quietly steering many investors off course, often without them realising it. In a market shaped by rising rates, global shifts, and post-COVID recalibrations, relying on outdated beliefs could be one of the most costly mistakes you make this year. Whether it’s the dominance of growth stocks, the belief that time in the market always wins, or dismissing cash as dead weight, these assumptions need a rethink.
Investing Myths 2025 – How Market Memories Can Mislead You
Your financial “memory bank” is shaped by the market conditions you’ve lived through—COVID-era rebounds, falling interest rates, tech booms. But these experiences can distort your future expectations.
“Your experience of the past is a reasonable guide to the future only if the future turns out to resemble the portion of the past that you’ve lived through.” – Jason Zweig
👉 If you’re planning your retirement or rebalancing your portfolio, it’s time to rethink what “normal” really looks like. You might benefit from this perspective: The Power of Perspective.
Myth #1: Growth vs Value Investing in 2025 and Why It’s Time to Rethink Your Portfolio
Over the past decade, growth investing—focusing on high-growth companies like Apple, Nvidia, and Tesla—dominated portfolios.
But in 2025, the tables are turning. Value stocks—those trading at lower prices relative to earnings—are back in favour. Warren Buffett’s Berkshire Hathaway is up 17.3% this year, while the Nasdaq has dropped 10.9%.

Myth #2: U.S. Stocks Are the Only Place to Be
For the last 20 years, the U.S. dominated global investing. But in 2025, international stock markets are outperforming the S&P 500 by more than 14 percentage points.
Historically, global markets have had long periods of outperformance. From 1971 to 1990, developed international markets consistently beat the U.S. market.
The MSCI ACWI ex USA Index is currently outperforming the S&P 500 in 2025.

Myth #3: Time in the Market Always Wins
Jeremy Siegel’s book Stocks for the Long Run made the case that stocks always beat bonds over 20+ years. But updated research shows that’s not always true. There are multiple 20-year periods where bonds outperformed stocks after inflation, most recently ending in 2012.
“Stocks aren’t guaranteed to beat bonds—even over long periods.”
If your strategy is to simply “ride it out,” it may be time to also consider asset diversification and flexible portfolio construction.
Recent research from Edward McQuarrie shows that stocks haven’t always outperformed bonds, even over 20 years.”

Myth #4: Cash is Trash
From 2009 to 2021, cash was almost useless. But in 2025? It’s a different game.
With Treasury bills and money market funds yielding over 4%, cash is outperforming stocks and beating inflation.
If you’re not actively using cash as a strategic asset class, you’re leaving opportunity on the table. We explore this idea further in: 5 Reasons to Invest in Shares or Keep Money in Your Offset Account
Myth #5: Gold is Always a Safe Haven
Gold often shines during the crisis, like now. But history shows it can stagnate for decades. It took nearly 30 years for gold to recover from its inflation-adjusted 1980 high.
“Gold is gleaming now, but it could tarnish when calm returns.”
That doesn’t mean gold is bad. But don’t build your wealth plan on short-term emotion. Use it as a hedge, not a hero.
What This Means for You
Being a successful investor isn’t about predicting the future. It’s about recognising when the rules have changed—and adapting before the crowd does.
Here’s what you can do now:
- Review your growth vs value exposure
- Consider international assets
- Use cash strategically, not passively
- Check your long-term assumptions—do they still hold up?
