How to think about SPY

An index fund like SPY gives you one-ticket exposure to a basket (~500 holdings) rather than a single company, so your outcome depends on the group, not one name. Because it’s market-cap weighted, the largest holdings above drive most of its moves — worth knowing if you already own those names directly, since you may be more concentrated than you think.
