There are tradeoffs. It certainly correlates, and there's risk to that. At the same time, your knowledge about the domain may let you make better investments, growing more companies may mean more demand for you as an individual contributor, and it's probably good networking. I think if you've chosen to be a journalist, it's probably because you believe there's money to be made in journalism and/or because you believe that journalism is making the world better, and in either of those cases it seems a worthwhile use of your excess funds/effort. You should probably have a separate rainy day fund that's un- (or ideally anti-) correlated, and an uncorrelated retirement fund. Y'know, with all the extra money journalists tend to have.
