Defining a stock's sector

[Dividend Watcher]

Generally I use what's on the S&P data sheet available from my brokerage. Then I adjust as necessary to make sense just a you mentioned with CVX. They're an energy stock in my book same as the drillers and pipelines. I don't know what would classify as an energy company if you took out the aforementioned and included them in basic materials. Utes have their own classification so it's not them. Solar?
