Hello there, I am fairly new here and I hope I can get an answer to my question here
So… here my question, I try to formulate it as clearly as possible:
For a calculation I need to know the proportion of a single company to the whole branch. For example I want to know how big AAPL in technology is… So I would take the market cap of AAPL, but for my calculation I still need the total size of that industry.
Can anyone help me with this (where can I get that info and does market cap make sense in this context)
I don’t think you can trust Fidelity since they are a retail shop with their own agenda and thoughts. Do some primary reserach: just get a list of all the companies and divide them into sectors and then add up all of the companieses sizes together for a given industry. Then you will have the size for each industry
I found fidelity before, but as @frankybarnes stated, I didn’t think their numbers were entirely correct. So when I thought about how to find that size of an industry, I would look at all the companies from S&P 500, divide them into groups and then add up their market cap. But… that is exactly what fidelity did, so I will test some of their sizes myself with manual calculation, but if that matches fidelity, I think that they can be trusted.
find a market cap weighted ETF for the sector… calculate the percentage they use for AAPL. then divide AAPL market cap by its percentage. boom. you have the size of the industry.
