🇺🇸 S&P 500
The 500 largest US companies in a single asset, in dollars. It's the showcase of American capitalism — and the index that has generated the most wealth in the world over decades.
📘 What it really is
The S&P 500 is an index that pools the 500 largest companies listed on US stock exchanges — Apple, Microsoft, Amazon, Nvidia, Google, and other giants you use every day. Buying the index means buying a small piece of all of them at once.
Why is it so talked about? Because over the long term, it has been the index that most consistently created value in the world. American companies dominate technology, global brands, and innovation — and the index renews itself, replacing weakening companies with growing ones.
Since it's priced in dollars, you gain in two ways: from the companies' appreciation and from the dollar strengthening against the real. It's equities + currency hedge in a single asset.
⚙️ How it moves
It's variable income (equities): it rises and falls with corporate earnings, US interest rates, and global sentiment. It tends to rise over the long term, but goes through sharp drops (-20%, -30%) from time to time. The difference is that historically it has always recovered and made new highs.
Today the index is concentrated: a few technology giants carry a lot of weight. That turbocharged the recent rally, but increases risk if those companies stumble.
🛡️ The risk
The risk is entering near peaks with stretched valuations. When the index is expensive (high valuations) and at all-time highs, the risk of a strong correction increases — and you might spend years in the red before recovering.
It's not a risk of "going bankrupt" (these are the best companies in the world), but of buying expensive and waiting a long time. That's why the classic strategy is to invest gradually, every month, without trying to time the top.
✓ Where it makes sense
For long-term global exposure, dollar-denominated and of the highest quality. Ideal to accumulate gradually (monthly contributions), preferably outside peaks of euphoria.
✗ Where to avoid it
Going all-in near historical peaks with stretched valuations and widespread euphoria. And never with short-term money — equities need years.
