Registering more than one type of business

Hi, I am trying to register as self employed for the first time. I work in the fitness industry and I am paid as a free lancer which I began this year. As a second stream of income I will in the near future be selling some investments which will also require a self assessment. When registering it asks if the business is in investing. As I am primarily concerned about the fitness business at the moment and have not yet sold any investments I was unsure whether to say yes/no to this question.

Hi Andrew,
Your answer would be no as you are currently registering for the fitness self employment.
Thank you.
