Goldman Sachs Outweighs Microsoft in This Popular Dow ETF, and Share Price Is the Only Reason

Here is a number every Dow ETF holder should know. Goldman Sachs carries a market value of roughly $272 billion. Microsoft is worth about $3.7 trillion. Yet inside the SPDR Dow Jones Industrial Average ETF (NYSEARCA:DIA), Goldman gets a bigger slice of your money than Microsoft. The only reason is share price.

Share Price Sets Your Weights

DIA tracks the Dow Jones Industrial Average, which is price-weighted. A stock with a higher dollar price per share gets a larger weight in the index, regardless of the company’s revenue, profit, or market capitalization. Goldman Sachs (NYSE:GS | GS Price Prediction) closed at $923.99 on September 24, 2026. Microsoft (NASDAQ:MSFT) closed at $497.15. That gap, and only that gap, is why Goldman outranks Microsoft in the fund. Weights drift daily as prices move.

If Goldman did a 2-for-1 stock split tomorrow, nothing about the business would change. Same revenue, same profit, same employees. Its weight in the Dow, and therefore in your DIA position, would roughly halve. A Microsoft split would do the same. Caterpillar sits near the top for the same reason Goldman does. The arithmetic is purely mechanical, yet it decides how your retirement dollars get allocated.

Real Cost Sits Elsewhere

DIA charges a modest expense ratio, and cheaper mirrors exist. For example, the Vanguard S&P 500 ETF (NYSEARCA:VOO) which tracks the S&P 500 runs at just 0.03% as of its March 2026 fact sheet, or roughly $3 a year on a $10,000 stake. DIA’s headline fee is higher (0.16%), and over 20 years that drag compounds.

A Financials Tilt You Did Not Choose

Price weighting also produces sector distortions nobody deliberately picked. Because Goldman and other high-priced financial names sit near the top, DIA carries a heavier financials weight than a market cap S&P 500 fund does, and a lighter weight in the mega cap technology names that dominate the broader market. A retiree who bought DIA for blue chip diversification may effectively be running a financials-heavy, tech-light portfolio without knowing it. That is a real active tilt, produced by share price arithmetic rather than any strategist’s view.

Cheaper Mirrors, Different Exposure

If you want the largest US companies weighted by how large they actually are, a market cap S&P 500 fund does that job for a fraction of the cost. Vanguard’s fund at 0.03% is the cleanest example, and iShares and State Street offer near-identical products. You lose the Dow 30 label and pick up roughly 470 more names, but you stop letting share price decide your allocation.

What to Check Before You Buy

DIA suits an investor who specifically wants the 30 Dow names and understands how they get weighted. It fits poorly for anyone who assumed an index fund owns the biggest companies in proportion to their size. Before you buy, pull the current top ten weights, add them up, and ask two questions. How much of your money sits in a handful of high-priced names? And are those names there because the companies dominate their industries, or just because their share prices are large?
