ETF or stock-picking? The honest answer for the DIY investor

2026-06-22 ·

The S&P 500 ETF remains the best choice for the majority of investors: near-zero fees, instant diversification, no stock selection effort needed. A maximum quality filter may improve risk-adjusted returns, but without any guarantee of outperformance. The two approaches are complementary, not opposed.

The conventional wisdom: ETFs almost always win

According to S&P Global's SPIVA studies, between 80 and 90% of actively managed equity funds underperform their benchmark index over ten years. The iShares S&P 500 ETF (IVV) or Vanguard's (VOO) gives you exposure to the 500 largest US companies for 0.03% in annual fees.

The quality-filter argument: we're not doing the same thing

When I talk about a portfolio made up exclusively of maximum-quality-score companies, I am not doing active management in the classical sense. I am not making macroeconomic bets. I am not trying to time the market. I am applying a strict fundamental filter: only companies that simultaneously satisfy all ten quality criteria enter the portfolio.

The problem with the S&P 500: 500 stocks, very mixed quality

The S&P 500 is cap-weighted. Apple, Microsoft, Nvidia each represent more than 5% of the index. But the index also holds hundreds of cyclical, indebted companies with thin margins. By buying an S&P 500 ETF, you inevitably buy those low-quality companies.

Have maximum-quality companies outperformed the S&P 500?

Over the past five years, several companies with maximum quality scores did outperform the index: Qualys (QLYS), Kinsale Capital (KNSL), Mastercard (MA), PayPal (PYPL), Moody's Corporation (MCO). But the honest answer is: there is no guarantee. Fundamental quality improves the probability of outperformance — it does not guarantee it.

The right mental framework: complementarity, not opposition

My personal position: these two approaches are not opposed. A sensible portfolio could combine a core S&P 500 ETF allocation (60 to 70% of the portfolio) with a concentrated stock-picking sleeve focused on maximum-quality companies at reasonable valuations (30 to 40%).

The hidden costs of stock-picking

If you value your time at $50 per hour and spend 100 hours per year on your portfolio, that is $5,000 in implicit cost. On a $50,000 portfolio, that is 10% per year. A 0.07% ETF on the same portfolio costs $35 per year.

My conclusion: ETF first, quality filter if you want to go deeper

If you are starting out or short on time — the S&P 500 ETF is the best answer. If you want to go further and apply a disciplined fundamental quality method — the maximum quality filter is a serious starting point.

FAQ

Do S&P 500 ETFs really beat 80 to 90% of active managers?

Yes, this is a statistical reality documented by S&P Global's SPIVA studies over twenty years of data.

Is filtering only for maximum-quality companies really different from active management?

Yes, on one key point: intent. Classical active management seeks to anticipate which companies will outperform. The quality filter seeks to eliminate structurally low-quality companies.

Why does the S&P 500 hold low-quality companies?

Because the index is built on market capitalisation and liquidity criteria, not fundamental quality.

Which companies have a maximum quality score in your screener?

Companies that have reached a maximum quality score include Qualys (QLYS), Kinsale Capital (KNSL), Mastercard (MA), PayPal (PYPL), and Moody's Corporation (MCO).

Can you combine ETFs and stock-picking in the same portfolio?

Absolutely, and it is probably the most sensible approach for a serious DIY investor.
