What is an ETF?
An exchange-traded fund (ETF) is an investment fund that comprises stocks and index funds. ETFs are traded on stock exchanges (like stocks) and track the performance of some underlying asset or collection of assets (like index funds). They allow investors to diversify risks and invest in a broad basket of securities without having to directly purchase all of the securities.
ETFs also allow investors to take positions in certain specific industries. For example, an investor who is bullish on electric vehicles may invest in an electric vehicles-themed ETF that tracks a basket of electric vehicles-related stocks. They can include battery-producing companies and AI-based software companies.
History of the SPDR S&P 500 ETF
The SPDR S&P 500 ETF is the world’s largest ETF and tracks the performance of the S&P 500 stock market index.

The ETF was designed by Nathan Most and Steven Bloom. The SPDR S&P 500 ETF is the most widely traded ETF in the world, with an average trading volume of 80 million shares.
S&P 500 vs. SPDR S&P 500 ETF
As can be seen from the graph above, the SPDR S&P 500 ETF does a very good job of closely tracking the S&P 500 stock market index. However, it is not an exact tracker and does occasionally fail to effectively track the S&P 500. Such errors are very small in magnitude and can be difficult to spot. The easiest way to spot the errors is to graph the two data series (the S&P 500 index and the SPDR S&P 500 ETF) in their first derivatives, i.e., their rates of change.
The blue line and the orange line plot the percentage change in the S&P 500 index and the SPY ETF, respectively. The black line plots the difference between the two series. For example, there is a 0.5% difference between the change in the S&P 500 index and the SPY ETF in June 2019 (marked by a red arrow). In this case, the change in the S&P 500 index was 0.5% more than the change in the SPY ETF.
