Not 500 equal slices
VOO's report lists 506 stock lines, because a few companies have more than one kind of share. The ten largest lines made up 36.49% of its stocks.
| Holding | Share of the fund's stocks | Out of every $1,000 |
|---|---|---|
| NVIDIA | 7.53% | $75 |
| Apple | 6.61% | $66 |
| Microsoft | 4.31% | $43 |
| Amazon | 3.63% | $36 |
| Alphabet class A | 3.26% | $33 |
| Broadcom | 2.78% | $28 |
| Alphabet class C | 2.60% | $26 |
| Micron | 2.02% | $20 |
| Meta | 1.92% | $19 |
| Tesla | 1.84% | $18 |
Alphabet appears twice. Taken together, its two classes were 5.85%, or $58 out of every $1,000.
Why the weights look like this
The index weighs each company by its market value: its share price times the number of shares. When a company's price rises, it becomes a larger part of the fund. Nobody at the fund decides this. It follows the rule.
So you end up owning more of whatever has already gone up. That helps while those companies keep rising, and it hurts more if they fall.
What it protects you from, and what it does not
- It protects you from one company failing. If Tesla went to zero, you would lose about 1.84% of this fund, not everything.
- It does not protect you from the market falling. When most shares fall together, the fund falls with them.
- It may not spread you as widely as you think. If you hold this fund, a technology fund and some NVIDIA shares, you may own the same few companies three times over.
Read it yourself
Funds must report their holdings to the SEC every quarter, and the report becomes public about 60 days after the quarter ends. So what you read is a little old, and it is what the fund itself filed, not a summary someone wrote about it.
Check it yourself
Each of these companies files its own reports. Check a claim about any of them.
