Key Facts:
- Ticker Symbol: SPY

Why is SPY So Popular?
1. Diversification
SPY provides instant diversification across 500 large-cap U.S. stocks. This helps reduce the risk associated with investing in individual stocks.
2. Liquidity
SPY is one of the most traded ETFs, ensuring high liquidity. Investors can easily buy or sell shares without significantly affecting the price.
3. Low Cost
With a low expense ratio, SPY is cost-effective for both long-term investors and short-term traders.
4. Performance
Historically, the S&P 500 has delivered strong long-term returns. Since SPY mirrors this index, it generally performs well over time.
How Does SPY Work?
When you invest in SPY, you’re essentially buying a slice of each company in the S&P 500. The ETF allocates its funds to stocks based on their market capitalization within the index. As the value of the underlying stocks changes, SPY’s price changes proportionally.
Example:
If Apple comprises 6% of the S&P 500 and its value rises, the price of SPY will also reflect that growth proportionately.
