S&P 500 Companies: A Complete Visual Breakdown
S&P 500 companies hold $7.1 trillion in assets, and account for close to 80% of available market capitalization on U.S. stock exchanges.
The index serves as a barometer for the U.S. stock market, covering the largest public U.S. companies by market capitalization. Often, it reflects investor sentiment and is considered an indicator for U.S. economic health.
As the S&P 500 enters a bull market after the longest downturn in decades, the above graphic shows the entire makeup of one of the world’s largest markets.

Over the last decade, big tech names have dominated the index.
The tech sector makes up over 26%, with Apple, Microsoft, and Nvidia as the top S&P 500 companies by market capitalization. Despite interest rates climbing at warp speed, a select number of big tech names have maintained, or even expanded their influence on the index over the last year.
In many cases, investor demand for AI-related stocks has fueled these increases.
Amazon is the third-largest company in the index. While shares tumbled in 2022 amid slowing sales, they have since rebounded by about 46% this year. Like Amazon, consumer discretionary firm Tesla has seen a strong reversal as the index’s 10th biggest stock by weight.
In the financial sector, Berkshire Hathaway has the highest weight (1.7%) while UnitedHealth Group (1.3%) is the top in health care. The health conglomerate even towers above JP Morgan Chase, the biggest bank in America.
S&P 500 Sectors and the Market Cycle
Below, we show the 11 sectors in the S&P 500, organized by weight and their typical performance over the business cycle:
- Cyclical: Rise and fall with the market cycle, often correlated to expansions or contractions
- Defensive: Typically are negatively correlated to the market cycle, with more stable earnings and dividends
Numbers may not total 100 due to rounding.
Information technology, health care, and financials have the highest share in the S&P 500. Together, they cover over half the index.
S&P 500 Companies: Mixed Signals in 2023
In many ways there are two major themes playing out this year so far for U.S. equities, which is the best-performing asset class year to date.
First is that seven big tech companies—Apple, Microsoft, Nvidia, Google, Tesla, Meta, and Amazon—are driving virtually all of the index’s gains. These companies have seen double or triple-digit returns this year so far. As of May 31, tech sector ETFs saw $8 billion in inflows to date, the highest across any sector.
Secondly, the energy and health care sectors have seen the highest outflows, at $9 billion and $4 billion, respectively.
Even with interest rates hitting 15-year highs, extreme greed is in the market, based on the Fear and Greed Index. This may signal higher risk in the S&P 500, since a hit to these few companies with high weightings could significantly affect the broader index.
Ranked: The World’s Top Diamond Mining Countries, by Carats and Value
Who are the leaders in rough diamond production and how much is their diamond output worth?
Ranked: World Diamond Mining By Country, Carat, and Value
Only 22 countries in the world engage in rough diamond production—also known as uncut, raw or natural diamonds—mining for them from deposits within their territories.
This chart, by Sam Parker illustrates the leaders in rough diamond production by weight and value. It uses data from Kimberly Process (an international certification organization) along with estimates by Dr. Ashok Damarupurshad, a precious metals and diamond specialist in South Africa.
Rough Diamond Production, By Weight
Russia takes the top spot as the world’s largest rough diamond producer, mining close to 42 million carats in 2022, well ahead of its peers.
Russia’s large lead over second-place Botswana (24.8 million carats) and third-ranked Canada (16.2 million carats) indicates that the country’s diamond production is circumventing sanctions due to the difficulties in tracing a diamond’s origin.
Here’s a quick breakdown of rough diamond production in the world.
|5||🇿🇦 South Africa||9,660,233|
|10||🇸🇱 Sierra Leone||688,970|
|18||🇨🇮 Cote D'Ivoire||3,904|
|19||🇨🇬 Republic of Congo||3,534|
Note: South Africa’s figures are estimated.
As with most other resources, (oil, gold, uranium), rough diamond production is distributed unequally. The top 10 rough diamond producing countries by weight account for 99.2% of all rough diamonds mined in 2022.
Diamond Mining, by Country
However, higher carat mined doesn’t necessarily mean better value for the diamond. Other factors like the cut, color, and clarity also influence a diamond’s value.
Here’s a quick breakdown of diamond production by value (USD) in 2022.
|5||🇿🇦 South Africa||$1,538M|
|9||🇸🇱 Sierra Leone||$143M|
|19||🇨🇬 Republic of Congo||$0.20M|
|20||🇨🇮 Cote D'Ivoire||$0.16M|
Note: South Africa’s figures are estimated. Furthermore, numbers have been rounded and may not sum to the total.
Thus, even though Botswana only produced 59% of Russia’s diamond weight in 2022, it had a trade value of nearly $5 billion, approximately 1.5 times higher than Russia’s for the same year.
Another example is Angola, which is ranked 6th in diamond production, but 3rd in diamond value.
Both countries (as well as South Africa, Canada, and Namibia) produce gem-quality rough diamonds versus countries like Russia and the DRC whose diamonds are produced mainly for industrial use.
Which Regions Produce the Most Diamonds in 2022?
Unsurprisingly, Africa is the largest rough diamond producing region, accounting for 51% of output by weight, and 66% by value.
|Rank||Region||Share of Rough|

However diamond mining in Africa is a relatively recent phenomenon, fewer than 200 years old. Diamonds had been discovered—and prized—as far back as 2,000 years ago in India, later on spreading west to Egyptian pharaohs and the Roman Empire.
By the start of the 20th century, diamond production on a large scale took off: first in South Africa, and decades later in other African countries. In fact between 1889–1959, Africa produced 98% of the world’s diamonds.
And in the latter half of the 20th century, the term blood diamond evolved from diamonds mined in African conflict zones used to finance insurgency or crime.
