    As a market-cap weighted fund, SPY heavily leans on mega-caps like Apple, Microsoft, and Nvidia.

🧠 My Take: Why I Personally Choose SPLG Over SPY

There’s no question — SPY is one of the most reliable and widely trusted ETFs in the world. It’s great for instant exposure to America’s top 500 companies, and it trades more like a stock than almost any other ETF out there.

But personally, I prefer SPLG — which tracks the exact same index with a much lower expense ratio of just 0.02%. It gives me the same exposure, strong liquidity, and full transparency — but in a more cost-effective package.

For long-term investors, those small fee differences really add up. That’s why SPLG is my go-to core holding for the S&P 500.

That said, SPY remains the gold standard in many ways. If you value legacy, liquidity, and institutional trust — you can’t go wrong with it.
