Market Cap by Sector Stock Visualization

Jul 20, 2016: 9:01 AM CST

Which stocks in which sectors have the largest (smallest?) Market Cap?

Let’s take a look at an innovative chart and find out!

From the Maps section of Financial Visualizations (, we can see the color-breakdown of sector and the market cap of each stock in that sector.

We’re most interested in knowing which stocks are the largest in each group and this chart makes it clear.

Just to name a few, Exxon-Mobil (XOM) is the largest of the Materials sector while Apple – the largest stock of all – is the greatest of the Consumer Goods sector.

Google – followed by Microsoft – is the largest of the Technology Sector.

Berkshire Hathaway is the largest Financial stock, Johnson and Johnson is the largest Health Care stock, and General Electric (GE) is the largest Industrial Goods stock.

Here’s something else that’s interesting – Facebook,, Johnson & Johnson, and Berkshire Hathaway all have similar market caps of about $350 billion.

Most stocks in the S&P 500 have a market capitalization beneath $50 billion.

Perhaps you can already see the challenge in specific classification of stocks in sectors.  Is Apple a technology stock or a consumer goods stock?

Nevertheless, you can have some fun – and learn valuable insights – by playing around with this and other tools.

    Yes, it’s very true and I strongly believe Forex is no magic, but all about hard work and planning, if we are capable of doing that then we shouldn’t be worried about too much. I always focus on good plan to make things work out correctly for me and I must say, it’s so much easier with OctaFX broker given their mouth-watering conditions which include tidy spreads starting from 0.1 pips while there is also cTrader platform to work on!
