Investing in the S&P 500 is one of the most time-tested ways to build long-term wealth.
But here’s the twist — there isn’t just one S&P 500 ETF.
In fact, several of the most popular ETFs — SPY, VOO, IVV, and SPLG — all track the exact same index.
So how do you choose the right one?
At a glance, they seem identical. But under the hood, each comes with its own structure, cost, and trade-offs.
Some are better for traders. Others for retirement. Some for maximum efficiency with small accounts.
If you’ve ever wondered “Does it really matter which S&P 500 ETF I pick?” — this post is for you.
Let’s break them down, side by side.
