Working as a research analyst in a stock brokerage firm

I wanted to ask a question about the job of research analyst in a stock brokerage firm or mutual fund. My degree major is finance so I want to know if working as a research analyst for any stock market company is halaal? Basically, the job is to do research on companies, look at their financial statements and analyse their performance and then give a recommendation on whether to buy the stock or sell it. I understand that investing in Shari'ah compliant stocks are allowed but I won't be investing. I'll just be researching and giving opinions. Also, I won't be researching on banks and insurance companies whose business is unlawful. So is this job halaal?
