A Question Worth Taking Seriously
For most of modern financial history, investing was treated as a male domain. The imagery, the language, the products, and the professionals were all overwhelmingly oriented toward men. Women were largely absent from the conversation, both as clients and as subjects of serious research.
That is changing. Rapidly. And as it does, a question that once felt almost provocative has become genuinely important: when it comes to investing, do women actually outperform men? And if so, why?
The answer, as it turns out, is not a simple yes or no. It is a story about behaviour, confidence, structural barriers, and a global shift in wealth that is going to reshape the investment landscape for decades to come. Whether you are a woman thinking about your own finances, a couple navigating financial decisions together, or simply someone who wants to understand what makes for effective long-term investing, the evidence here is worth understanding.
What the Research Actually Finds
Let us start with the data, because the data is genuinely striking.
A study by Warwick Business School, tracking the trading behaviour and investment returns of 2,800 investors over three years in partnership with Barclays, found that women's portfolios outperformed the FTSE 100 by 1.94% annually, compared to just 0.14% for men. The gap between male and female investor returns was 1.8 percentage points per year. Over a decade, that difference is not marginal. It is transformative.
Fidelity Investments, which manages retirement accounts for millions of people across the United States and beyond, analysed its own client data and found that women outperform men by approximately 0.4% annually. That may sound like a small number. Applied to a $500,000 portfolio over thirty years, it represents a meaningful difference in final wealth. Fidelity also found that women save a higher proportion of their income, investing an average of 9.8% of their paycheques into workplace retirement accounts.
Hargreaves Lansdown, one of the United Kingdom's largest retail investment platforms, found in its own study that women returned 0.81% more than men over a comparable period.
These are not isolated data points from a single study. They represent a consistent pattern, replicated across different markets, different time periods, and different types of investor. The question is not really whether the outperformance exists. It does. The more interesting question is why.
The Behaviour Gap: Why Women Tend to Trade Less and Earn More
The most consistent explanation for women's investment outperformance comes down to behaviour, specifically the behaviours that destroy returns over time.
Trading frequency
The Warwick Business School study found that women traded an average of nine times per year, while men traded thirteen times. That 44% difference in trading activity matters enormously for net returns. Every trade involves a cost, whether explicit in the form of commission or implicit in the form of bid-ask spread. More importantly, frequent trading almost always reflects an attempt to time the market. And market timing, as decades of evidence confirm, tends to destroy value rather than create it.
A landmark study of 35,000 brokerage accounts at the University of California, Berkeley by professors Brad Barber and Terrance Odean found that men traded 45% more than women, and that this excess trading cost male investors significantly in terms of net annual returns. The researchers attributed much of this to overconfidence, a tendency to believe that one's market judgments are more reliable than they actually are.
Staying the course through volatility
Perhaps one of the most practically significant differences between male and female investors shows up during market downturns, precisely the moments when the most value is at stake.
According to a Nationwide survey cited by Motley Fool, during periods of high market volatility only 8% of women liquidate their retirement accounts, compared to 15% of men. Selling during a downturn and missing the subsequent recovery is one of the most reliably wealth-destroying behaviours an investor can exhibit. Fidelity's 2023 research found that 51% of women said they stay the course when markets fall, compared to 43% of men.
Avoiding speculative trends
Women are also less likely to chase whatever is generating excitement in the moment. Research from Wells Fargo found that roughly 53% of women take a moderate investment approach while 55% of men prefer an aggressive strategy. The Warwick study found that men were significantly more drawn to what researchers called "lottery style" investing: low-priced, highly speculative shares with the potential for large but unlikely gains. Women consistently showed less appetite for these positions, preferring more established investments held over longer periods.
This pattern extends to newer asset classes. Gallup data found that 11% of male investors owned Bitcoin compared to just 3% of female investors at a comparable point in time. More recently, Fidelity's 2024 research found that 55% of male investors held cryptocurrency versus 43% of women. This is not an argument against cryptocurrency as an asset class. It is an observation about risk discipline.
The Confidence Paradox
Here is where the story becomes genuinely interesting, and a little uncomfortable.
Despite outperforming their male counterparts by measurable margins, women consistently rate their own investment ability lower than men do. A George Washington University study on financial literacy found that 71% of men self-identified as having a high level of investing knowledge, compared to 54% of women. Only 34% of women reported feeling comfortable making investment decisions, versus 49% of men.
Fidelity's 2021 research found that while 75% of women felt confident balancing a budget, just 19% felt confident selecting investments that matched their goals. Despite the evidence of superior returns, only a third of women who invest see themselves as investors at all, according to Fidelity's broader research.
This confidence gap has a self-reinforcing quality. Women who doubt their abilities are less likely to invest at all, less likely to invest in growth assets, and more likely to hold excessive cash. A 2024 Citizens Bank survey found that 84% of women said they lacked confidence in their ability to manage a financial windfall, compared to 73% of men. And a SoFi survey found that nearly half of female investors said their biggest regret was not starting to invest sooner.
The irony is layered. Women who do invest tend to make better decisions than men. But the confidence gap keeps many women from investing as much or as early as they could. The result is that women end up with smaller portfolios on average, not because of poor investment decisions, but because of delayed entry and over-cautious allocation.
The Structural Barriers That Still Exist
Acknowledging women's investment outperformance does not mean the playing field is level. It very clearly is not.
The wage gap and its compounding effect
According to Pew Research Center data from 2025, women in the United States earn approximately 85 cents for every dollar earned by men. The gap is wider in many other markets. Less income means less disposable capital to invest, smaller initial balances, and less compounding over time. The investment gap between men and women is, to a significant degree, a downstream consequence of the income gap.
The career interruption penalty
Women globally take on a disproportionate share of unpaid caregiving and domestic labour. Career interruptions for childcare, elder care, or family responsibilities reduce lifetime earnings, reduce pension contributions, and reduce the number of years over which investment compounding operates. These interruptions have long-term wealth consequences that extend well beyond the period of the interruption itself.
An industry built for a different client
For most of its history, the wealth management industry was designed by men, for men. The language, the marketing, the product structures, and the default assumptions embedded in financial planning tools were oriented toward the profile of a male breadwinner. Boston Consulting Group's 2024 research found that despite women adding an estimated $5 trillion to the global wealth pool every year, significant gaps remain in how well financial products and services meet women's specific needs and preferences. As BCG noted, women do not want products designed specifically for them in a superficial sense. They want advice and services that genuinely reflect their circumstances, concerns, and long-term objectives.
The Coming Shift: Women and the Great Wealth Transfer
Whatever gaps exist in the present, the trajectory of women's wealth globally points in one clear direction.
Cerulli Associates projects that $124 trillion will transfer from older to younger generations by 2048 in the United States alone. A significant portion of that will flow first to surviving spouses. Because women typically outlive men by several years, and because most couples have an age gap, CNBC's analysis of Bank of America Institute research estimates that women will inherit roughly 70% of this wealth. Approximately $54 trillion is expected to transfer to surviving spouses, of whom 95% are women.
Citizens Bank research projects that by 2030, women will control $34 trillion in investable assets, three times the figure at the start of this decade. McKinsey research cited by Goldman Sachs estimates that European women's assets may grow at 8.1% per year through 2030, compared to 2.7% for men.
This is not a distant prospect. It is already underway. Women now make up more than 11% of the world's millionaires, nearly double the share in 2016, according to Julius Baer. UBS reports that 45% of its wealth management clients are now women, and that this share is growing.
The wealth management industry, which has spent decades calibrating its services to male clients, is only beginning to adapt to this shift. Lombard Odier's research found that 80% of its female clients and business partners believe sustainable investments will outperform or match more traditional alternatives, reflecting a preference for purpose-aligned investing that is reshaping how capital is allocated globally.
What Men Can Learn from Women's Investing Behaviour
This is not an article about winners and losers. The behaviours that tend to make women effective investors are not gender-specific. They are learnable by anyone.
Trading less frequently, staying invested through market downturns, resisting the pull of speculative trends, diversifying deliberately, and working with trusted advisers are all practices that improve outcomes regardless of who is doing the investing. Betterment found that among clients who deviated from its recommended asset allocation, men were twice as likely to move into a 100% equity allocation compared to women, a risk-concentration that often cost them dearly in volatile periods.
The UBS wealth management research on women investors offers a useful framing: women tend to reach for investment decisions only when they feel they have the information needed to make them confidently. As Katie Nixon, Chief Investment Officer at Northern Trust, has noted, this can appear as lower risk tolerance but is often better understood as a rational requirement for adequate information before committing. Once women have that information, their investment profile tends to be similar to men's, but with better execution discipline.
That combination of research, patience, and discipline is not a gendered trait. It is simply good investing.
A Note on Global Variation
The picture varies meaningfully across different parts of the world, and it is worth acknowledging that.
In parts of Asia, women play a central role in managing household finances. BCG's research on women's wealth found that in China, women tend to dominate household financial management and make up a significant proportion of private banking clients. In Japan, by contrast, structural barriers to workforce participation and wealth accumulation mean men still control more than 80% of national wealth, even as women's share is growing.
In many parts of sub-Saharan Africa, South Asia, and the Middle East, cultural and structural factors continue to restrict women's access to financial services, inheritance rights, and investment participation. The global story of women and investing is one of enormous diversity, and the data from the US, UK, and Europe should not be mistaken for a universal picture.
What does hold broadly, however, is the direction of travel. In virtually every market where barriers have been reduced, women who invest have demonstrated the behavioural discipline that produces strong long-term outcomes. The evidence strongly suggests that unlocking greater women's participation in global capital markets is not just a matter of equality. It is a matter of financial efficiency.
How Celerey Works with Women Investors
At Celerey, we have seen in our own client work what the research confirms: women who engage actively with their financial planning tend to be thoughtful, goal-oriented, and focused on outcomes that go beyond pure return maximisation. They think about security, legacy, purpose, and the financial wellbeing of the people around them. Those are not constraints on good investing. They are the foundations of it.
We work with women at every stage of the wealth journey, from those building wealth through careers and business ownership, to those managing inherited assets or navigating major life transitions such as divorce, bereavement, or retirement. We believe the best financial advice is advice that reflects your actual life, not a generic template designed for someone else's circumstances.
If you would like to have a conversation about your investment approach and whether it is genuinely working for you, the Celerey team is here to help.
