Answer 1

Answer

Introduction of SPX Index

It is a is a stock market index that measures the stock performance of 500 large companies listed on stock exchanges in the United States. It is one of the most commonly followed equity indices, and many consider it to be one of the best representations of the U.S. stock market.

Its relationship to the ETF

Index ETFs are exchange-traded funds that seek to replicate and track a benchmark index like the S&P 500 as closely as possible. They are like index mutual funds, but whereas mutual fund shares can be redeemed at just one price each day (the closing net asset value (NAV)), index ETFs can be bought and sold throughout the day on a major exchange like a share of stock. With an index ETF, investors gain exposure to numerous securities in a single transaction.

Index ETFs can cover U.S. and foreign markets, specific sectors, or different asset classes (i.e. small-caps, European indices, etc.). Each asset incorporates a passive investment strategy, meaning the provider only changes the asset allocation when changes occur in the underlying index.

The S&P(SPX) 500, often just called "the S&P," is a market-cap-weighted index of 505 large-cap U.S. stocks, representing approximately 80% of the market value of the U.S. stock market. An S&P 500 ETF is a good, inexpensive, way to get exposure to the U.S. stock market.

Because index-tracking ETFs will follow the performance of the Index, one of the most important determinants of long-term returns is how much it charges in fees.

Liquidity indicates how easy it will be to trade an ETF, with higher liquidity generally translating to lower trading costs. Trading costs are not a big concern to people who want to hold ETFs long term, but if you’re interested in trading ETFs frequently, then it’s important to look for high-liquidity funds to minimize trading costs

SPY.

SPY is an exchange-traded fund (or ETF) managed by State Street Global Advisors. By purchasing one share of SPY (currently valued at over $241), you own small, allocated percentages of every stock on the S&P 500

If you want to invest in an inexpensive S&P 500-based index fund, the SPY ETF is a smart option. For those who don't have the time, energy, or interest to choose and manage individual securities, parking most or all of your long-term dollars in it is a very reasonable move.
