Investing in the stock market is probably the best way to increase your net worth over time and a straightforward way to make at least $50K per year from your home. Most experts agree that the best way to invest in the stock market is to put your hard-earned money into a broad market index fund.
The SPX is just a stock index comprised of the 500 larges U.S publicly traded companies by market capitalization listed on the NYSE or NASDAQ. The size of the index is determined by share price multiplied by the number of outstanding shares. On the other hand, SPY is the ticker of SPDR S&P 500 ETF, one of the most popular exchange-traded funds worldwide.
The reality is that you can’t buy SPX as a single stock. Instead, you can buy one of the hundreds if not thousands of ETFs based on it. The only way to trade the SPX itself is thru option trading – not the best way to start investing if you’re a beginner.
