How Is The Stock Market Going Up In A Global Pandemic?

During a falling economy, like during the 2020 pandemic, the stock market actually grew many months.

This caused millions of people to scratch their heads in amazement.

Lots of people began to develop a distrust in the stock market.

If we inspect what really drives the stock market, we will make sense of these phenomena.

The US economy and world economy can decrease and US stock market can rise because the S&P 500’s top ten stocks make up 28% of the market.

Let Us Take a Look At Who These Top Ten Stocks Are

The S&P 500 reflects nearly all the largest stocks in the U.S., we often refer it to be synonymous with “the market” as a whole.

To simplify how to explain it, we need to realize the S&P index is really the U.S. stock index.

The Standard & Poor’s 500 Index, or S&P 500, is a market-capitalization-weighted index of exactly 505 large-cap U.S. stocks.

The index makes up 80% of the market value of the U.S. equities market.

Since it’s weighted by market cap, the largest stocks have a big impact on both the long-term performance and daily movement of the index.

This may shock you to know the 10 biggest stocks make up 28% of the index’s market value.

This means every investor should become familiar with these 10 giant companies so they can understand what drives the broader market.


This explains the original question of how the economy can be nose diving while the stock market is making gains.

Alphabet is the parent company of search-engine giant Google. Among its other products besides the Google search engine, Alphabet runs video sharing site YouTube. It’s notable that the company splits its stock into two main share classes. Google’s C shares are nonvoting shares, meaning they do not entitle the holder to take part in proxy votes. The A shares usually trade for slightly more than the C shares and carry voting rights. Each of these shares trades on the S&P 500, and each is large enough, by itself, to make the top 10 list. If we counted together the two share classes, it would place Alphabet 4th on this list and would make up 3.6% of the index. There are also B shares, which have disproportionate voting rights and are only held by Google insiders. The B shares do not trade on the open market.

6. Alphabet Inc. Class C Shares (GOOG)

Index Weighting: 1.8%

Market Cap ($B): 475.9

Revenue ($B) (4-Quarter Trailing): 171.7

Among its many holdings are insurance businesses such as GEICO, large energy and utilities businesses, a major railroad, consumer brands such as ice cream store Dairy Queen, and manufacturers such as aerospace parts manufacturer Precision Castparts Corp. It also owns an enormous portfolio of equities, which is why Berkshire Hathaway notably fell several places in the rankings. Those equities took an enormous hit when stocks dropped during the first quarter, absolutely crushing Berkshire’s first-quarter profits, and dragging down the company’s stock.
