Trader vs. Family Business

Which one would you include in your resume for better odds at getting back into IB / PE? I am a former IB Analyst in NY, did 2.5 year stint before leaving my job and NYC to help my dad with our family business. He was in poor health at the time and needed a trustworthy right hand. Business is manufacturing, not related to finance whatsoever. Working with my dad took about 30-40 hours of the week while I also did swing trading on the side which took approx 20 hours a week including research. And I turned a handsome alpha (40% over S&P500) in the last year and a half. Now my dad is in much better condition and for the last 5 months I've been working at a medium-sized company, doing a mix of finance and strategy work with the title "Associate".

I want to get back into the deal-making space and have my eyes on IB, PE, Corp Dev, anything M&A. No preferred industry. How should I put down this not-so-gap year on my resume to increase my odds? Keep in mind, the story would convince a lot of people if they got to hear me, but the resume needs to get me there first.

Thank you all for your responses.
