Your trading brokerage should have a way for you to see the sector, industry, and sub-industry of stocks you are researching.
For example, here is a Watchlist of the S&P 100 showing the first symbols and the sector, industry, and sub-industry that they belong to. This is from ThinkorSwim on the Charles Schwab platform.
If you don’t have a brokerage account yet you can use Finviz which shows the Sector and Industry.
NOTE: sometimes different platforms will call the sectors/industries different names.
For instance, there are differences with ABT, Abbott Laboratories.
Thinkorswim – Sector Health Care, Industry Health Care Equipment & Sales
Finviz – Sector Healthcare, Industry Medical Devices.
Wikipedia has a page that shows Sector>Industry Group>Industry>Sub-Industry.
If you are looking for an ETF for a Sub-Industry, you can use this list to find the name of the sub-industry. Then search for that name on an ETF site.
The easiest way to see how well a sector is performing on charts is to use a sector ETF. Several companies manage sector ETFs and one of the largest is State Street Global Advisors SPDR series.
We’ll use their symbols as examples but you can use other companies as well. There are many different sectors but below are some of the top ones.
