VOO or SPY – Quick Answer

VOO and SPY both track the S&P 500 Index, meaning they own a broad basket of large U.S. companies (Apple, Microsoft, Amazon, etc.).

• VOO is cheaper with lower annual fees (expense ratio ~0.03%).
• SPY is older and more liquid, which traders like.
  Both deliver nearly the same returns and holdings. (AInvest)

The Origin of VOO or SPY

• SPY launched in 1993 as the first U.S. ETF, managed by State Street Global Advisors under the SPDR brand. Its long history makes it one of the most traded funds.
• VOO was introduced later by Vanguard to offer a similar S&P 500 exposure but at a lower cost.
  Both tickers exist because multiple firms offer index ETFs, and investors choose based on fees, liquidity, and structure.
  VOO uses an open‑end fund structure, while SPY is technically a unit investment trust, which affects how dividends are handled. (Reddit)
