Equity returns remained high in 2020, in spite of the uncertainty and volatility caused by the coronavirus pandemic and related partial shutdowns. Initial public offerings (IPOs) ended the year with the highest rate of equity returns, which amounted to ** percent returns for investors. However, the most compelling financial story in the second half of the year revolved around the huge increase in IPOs via special purpose acquisition companies (SPACs).

In 2021, however, IPOs and SPAC mergers experienced negative returns. Why are NASDAQ and S&P 500 relevant benchmarks? The Nasdaq and the S&P 500 are two of the most important stock indices in the United States, if not the world. The Nasdaq Composite Index includes over 2,500 stocks listed on the Nasdaq stock market, which is the second largest stock exchange globally. The S&P 500 index tracks the stock value of 500 large companies, such as Facebook and Alphabet, listed on the New York Stock Exchange. What level of impact did the pandemic have on these indices? Over the past decade, both the NASDAQ Composite index and the S&P 500 index have skyrocketed in value. However, both indices took a hit in February and March 2020 when the uncertainty caused by the pandemic led to investors selling off assets en masse. This dip was short-lived and both indices had fully recovered by the third quarter.

To determine which companies, correspond to the technology sector, we use Yahoo Finance, where we rank the companies according to their “Market Cap”. After having the list of the Top 100 best valued companies in the sector, we proceeded to download the historical data of each of the companies using the NASDAQ website.

Regarding to the indices, we searched various sources to find out which were the most used and determined that the 5 most frequently used indices are: Dow Jones Industrial Average (DJI), S&P 500 (SPX), NASDAQ Composite (IXIC), Wilshire 5000 Total Market Inde (W5000) and to specifically view the technology sector SPDR Select Sector Fund - Technology (XLK).

Coronavirus sparks stock market chaos Stock markets plunged in the wake of the COVID-19 pandemic, with investors fearing its spread would destroy economic growth. Buoyed by figures that suggested cases were leveling off in China, investors were initially optimistic about the virus being contained.
