Active vs Passive Investing: Why the Debate Misses the Point
The right answer is rarely picking one camp over the other. It is knowing what each holding in your portfolio is for.
Somewhere between a friend’s boast about a stock that tripled and a headline warning that most fund managers fail to beat the market, most investors end up feeling they have to choose a side. Pick stocks and funds yourself, in the hope that careful research and good judgement will outperform the broader market. Or step back entirely, hold a diversified index fund, and accept whatever the market delivers.
Both camps have genuine convictions, and both can point to evidence that supports them. What gets lost in the argument is that the choice was never binary, and that the more useful question is not which camp to join, but what each part of your portfolio is trying to achieve.
What active investing involves
Active investing means picking individual stocks, bonds, or funds yourself, or paying a fund manager to do it for you, with the goal of beating the market rather than just matching it. It takes ongoing work: studying companies, watching the economy, and buying or selling as new information comes in. All of that research and trading costs money, and those costs have to be earned back through better returns before active investing is worth it at all.nasdaq
The data says that’s hard to do with any consistency. In 2025, 79% of actively managed US large-cap funds did worse than the S&P 5001, the fourth-worst year for active managers in the 25-year history of this research. Looking further back, the picture does not improve: over the fifteen years to the end of 2024, not one major US equity category saw most active managers beat their benchmark.
What passive investing involves
Passive investing means buying a fund that simply tracks a market index, such as the STI in Singapore or the S&P 500 in the US, instead of trying to beat it. No manager is picking favourites, there is barely any buying and selling, and the fees are much lower as a result.
Two costs are easy to miss, though. The first is tracking error: a passive fund almost never delivers the exact return its index reports. Fees eat into it a little, dividends take a few days to get reinvested, and the fund pays small costs each time the index changes its line-up. The second is the cost of simply buying or selling. Every trade involves a small gap between the price a seller will accept and the price a buyer will pay, known as the spread. For a heavily traded fund, this gap is tiny. For a smaller or less liquid one, it adds up.
There is a third thing worth knowing. A market index is not a neutral, scientific slice of “the market.” It is a list built by a commercial provider, which decides what goes in it and how much weight each company gets. Track that index faithfully, and you inherit every one of those decisions, including the ones that may not suit you. Singapore’s STI is a clear example: it covers just thirty companies, heavily weighted towards banks and property trusts, yet most Singaporean investors still treat local stocks as a core part of their portfolio. The same blind spot shows up in funds that sound far more global. The Nasdaq-100, often bought as broad exposure to technology, holds roughly half its value in just ten companies. “Passive” does not automatically mean “diversified.”
None of this makes passive investing the wrong choice. It simply means the honest version of the pitch is not “exactly the market return, minus a small fee.” It is closer to “close to the market return, minus a small fee, and a couple of small costs most people never hear about” — a difference that matters very little in large, liquid markets, but is worth knowing rather than assuming away.
How we approach this
At Life First Advisory, we don’t choose between forecasting the market and accepting a commercial index’s design without question. Both carry a hidden cost: forecasting is unreliable and expensive, and accepting an index blindly means inheriting concentration decisions that may have nothing to do with what you need. Instead, we utilise portfolios that spread broadly across thousands of companies, sectors, and countries. The weighting isn’t borrowed from a single commercial index. It’s guided by traits that decades of research show have reliably predicted differences in return over time — a company’s size, how cheaply it’s priced relative to its fundamentals, and how profitable it is, for equities; and for fixed income, how long until a bond matures and how likely the borrower is to repay. That is what genuine diversification looks like: breadth deliberately constructed, not breadth assumed because a fund happens to carry the word “index” in its name. It calls for discipline and patience rather than prediction, and a structure built to hold up across full market cycles, not just the calm stretches.
Research is equally clear that investor behaviour affects returns more than the choice of holdings itself, which is exactly where this approach earns its keep. It isn’t only about construction. It’s about the clarity to understand why each holding is there, the continuity to hold the strategy through a difficult quarter, and the confidence to stay invested when instinct says otherwise.
What deserves to change your allocation
This is where the active-versus-passive debate misses the point entirely: both camps argue about which vehicle wins, as though the vehicle were what mattered most. It isn’t. What matters is what the money is for, and whether the way it’s invested still serves that. A goal to fund a child’s first home, or to retire at a particular age, doesn’t move because a fund lagged its benchmark for two quarters. Market noise is loud and constant, and rarely, on its own, a reason to change anything.
What does deserve to change an allocation is a change in the goal itself — a milestone arriving sooner than planned, a shift in what you can comfortably risk, a change in family or business circumstances. That is a deliberate adjustment, made because the plan and the life it serves have moved together, and it is a different thing entirely from reacting to noise. We take the time, before any portfolio decision, to distil what matters most to you and set it out clearly, so the plan stays anchored to something that endures, rather than to whichever argument happens to be loudest this year.

Our Discovery Meeting is where we take a complete picture of your life and your portfolio, and build a strategy with the clarity, continuity, and confidence to match.
Two questions we hear most often
Doesn’t a globally diversified index fund solve the concentration problem?
Not automatically. A fund tracking a broad global or thematic index still inherits that index’s particular construction — which companies are included, and how heavily each is weighted. Some of the most popular “global” or technology-focused index funds are concentrated in a handful of mega-cap names, in much the same way the STI concentrates in banks and property trusts. The fix isn’t choosing a bigger-sounding index. It’s understanding what you hold and why.
If my portfolio is down, should I switch strategies?
Usually not on the basis of performance alone. A bad quarter, or a year where one approach outpaces another, is market noise, and reacting to it is one of the more reliable ways to damage a long-term plan. The better question is whether anything about your goals or circumstances has genuinely changed. If they haven’t, the portfolio probably hasn’t needed to either.
