Most brokerage firms will ask if you work for a public company or a FINRA-registered firm at account opening. If you didn't directly tell them you're employed by one it's still safe to assume they've gathered the information from your direct deposit information or from source-of-funds information sharing with your other financial institutions. If you work for a FINRA-registered firm they'll send a letter to your employer asking if they'd like your transaction information to be added to the data feed. I'm guessing they can facilitate the same for publicly traded companies and their employees but I've only ever worked on the financial firm side of things so I don't know for sure. Scary huh?
