What sets experienced investors apart from everyone else? Is it a privileged start in life, a finance degree, or access to insider knowledge the rest of us don’t have? It can be tempting to assume the world of confident, consistent investing belongs to someone else, someone wealthier, better-connected, or simply born into it.
Thankfully, the truth is more empowering than that. Investors who grow their wealth steadily, through bull markets and crashes, through economic uncertainty and opportunity, aren’t operating on secret information. They’re operating with a different mindset. One built on discipline, patience and simple rules.
The great news is that a capable mindset isn’t inherited, it can be self-taught. The key principles that guide the world’s most experienced investors are available to anyone willing to adopt them, so they can invest successfully in their own self-managed portfolios.
Here’s what they look like in practice.
They start, and they stay
As Warren Buffett, former CEO of Berkshire Hathaway, famously said, “the stock market is a device for transferring money from the impatient to the patient.”
Impatience is the enemy of investing, and time is truly your greatest asset. It doesn’t require expertise, a large starting sum, or perfect timing. It simply requires the discipline to start, and the resolve to stay.
Warren Buffett, arguably the most celebrated investor who ever lived, built his fortune not on short-term trades or market predictions, but on one remarkably simple idea stay in the market long enough and let compounding do the heavy lifting. Every year your money stays invested, it has the potential to grow, and then for that growth to grow again.
Impatience can be very costly. When markets dip, and they always do at some point, the instinct for many investors is to get out and wait for calmer waters. It feels rational. It feels cautious. In reality, it’s one of the most expensive mistakes you can make. Missing even a handful of the market’s best days, which often come immediately after its worst, can dramatically reduce your long-term returns.
Experienced investors know this, so they don’t try to time the market. They ride through it, and even often purchase the investments sold by those who are reactive and panic when markets take a tumble.
In much the same way as Buffett would recommend, you can start with small, contribute regularly, and let time and compounding do the work through Share Investing service, that lets you build your own portfolio from scratch, choosing from over 2,800 stocks, ETFs, bonds and mutual funds, all within a tax-efficient Individual Savings Account (ISA) or General Investment Account (GIA).
They keep their costs in check
“In investing, you get what you don’t pay for,” said American investor John Bogle. Every pound paid in fees is a pound that isn’t compounding, and over decades, that effect is staggering. A portfolio growing at 7% a year that carries 2% in annual fees will end up worth roughly half what it would have been at 0.5% fees over a 30-year period. Experienced investors are ruthless about cost efficiency, they scrutinise management fees, platform charges, and transaction costs, and they demand to understand what they’re paying for.
Share Investing service charges a simple, transparent custody fee of 0.35% per year n the ISA (capped at £45), and no custody fee for the GIA, with trades from just £3.95, so more of your money stays invested, where it belongs.
They spread their bets
As American economist Harry Markowitz said, “diversification is the only free lunch in investing.” Every business, sector or geography faces unique risks. Diversification is crucial for ensuring your wealth can withstand them. It’s about building a portfolio that isn’t overly dependent on any single company, sector, or geography performing well. Markowitz won the Nobel Memorial Prize for revolutionising the world of investing, by proving investors could reduce risk without sacrificing returns through diversification.
Even the most experienced investors acknowledge the limits of their own knowledge. A company that looks unbeatable can be disrupted overnight. A thriving sector can be hit by regulation or technology shifts. Diversification is how you protect your portfolio from the outcomes you didn’t predict, which there will always be.
A well-diversified portfolio might include equities across multiple markets, bonds for stability, and a range of sectors and asset classes. The goal isn’t to maximise returns in any given year but to avoid catastrophic losses that would take years to recover from.
ETFs are one of the most powerful diversification tools available to Do-it-Yourself (DIY) investors. A single ETF can give you exposure to hundreds of companies across an entire index, like the FTSE 100 or S&P 500, for a fraction of the cost of buying individual shares. platform gives you access to a wide range of equity and bond ETFs, making it straightforward to build a genuinely diversified portfolio in one place.
They don’t try to predict the future
“Far more money has been lost by investors preparing for corrections than has been lost in corrections themselves,” said Peter Lynch, who managed the Magellan Fund at Fidelity from 1977 to 1990, delivering an average annual return of 29.2% across 13 years, one of the best track records in history. His view on market timing was blunt don’t bother.
The seductive appeal of market timing, getting out before a crash and back in at the bottom, sounds simple and logical. In practice, it’s nearly impossible to execute consistently, even for professionals. The market doesn’t announce its turning points. By the time most people ‘know’ a correction is coming, it’s already priced in. And the cost of being wrong, even by a few days, can be severe.
Experienced investors don’t obsess over where the market is heading in the short term, the next week or next month. They focus on where it’s likely to be in five, ten, or twenty years, and the historical answer to that question is, usually, much higher. They use this long view to stay calm when headlines scream panic, and to keep investing even when the mood is gloomy.
Mutual funds pool money from many investors to buy a broad basket of assets, managed according to a defined strategy. Unlike individual stocks, they’re designed for steady, long-term growth rather than short-term trading, making them a natural fit for investors who want exposure to a market without trying to time it. Moneyfarm offers a selection of UK Mutual Funds across a range of markets and strategies.
They make decisions, not reactions
Benjamin Graham, widely regarded as the father of value investing and mentor to Warren Buffett, identified the real obstacle to investment success long before behavioural economics became a field it’s ourselves.
Markets move on emotion, fear drives sell-offs, greed drives bubbles. Investors are plugged into a constant stream of financial news and social media, and are more exposed to these emotional currents than ever before. Remaining disciplined with a long-term plan is a real challenge, but crucial to successful investing.
Experienced investors have a goal, and they stick to it. They set their strategy and they don’t let a bad week, or a scary headline, pull them off course. It’s the conscious decision to let long-term thinking win over short-term fear which usually pays off.
Buying individual company shares is where many DIY investors start, and where emotional discipline matters most. Share Investing service gives you access to UK, European and US listed stocks across a wide range of sectors, with real-time pricing and research tools to help you make informed decisions rather than reactive ones.
They have a plan, and they review it
“Know what you own, and know why you own it” is another quote from Peter Lynch.
A good investment plan has a goal at its heart retirement at a certain age, a property deposit, financial independence, a legacy for your family. With a goal in mind, you can make intentional decisions about risk, time horizon, and asset allocation, rather than just buying whatever seems interesting or popular.
But plans need reviewing markets change and so do personal circumstances. What made sense when you were 35 might not make sense at 50. Experienced investors set aside time, at least annually, to rebalance their portfolio, check it’s still aligned to their goals, and make considered adjustments. Not reactive ones.
portfolio tools make it easy to see exactly what you hold and how it’s performing against your goals. Set a reminder to review your portfolio at least once a year, rebalancing when needed to stay aligned to your risk appetite and timeline. Bonds are also available, and behave more steadily than equities making them a useful tool for balancing a portfolio as your goals or risk appetite evolve. As part of your annual review, it’s worth considering whether your equity/bond split still reflects where you are in life.
The bottom line
Reading about the habits of experienced investors is one thing, acting on them is another, and that gap between knowing and doing is where most people’s investment journeys stall. You don’t need a perfect portfolio or a crystal-clear view of where markets are heading; you just need a goal, a plan, and the willingness to stay the course. The six principles in this article aren’t the secrets of an elite few, they’re the habits of anyone who has ever built lasting wealth, and you now know them. The next step is yours.
Share Investing service gives you access to over 2,800 stocks, ETFs, bonds and mutual funds within a tax-efficient ISA or General Investment Account, with a transparent, low-cost fee structure that ensures more of your money stays invested and compounding for longer. Whether you’re building your first portfolio or adding self-directed investing alongside a managed strategy, everything you need is already there. The only thing missing is you.
