What's Your Sleep Number for Stocks?

An investor’s sleep number is the maximum percentage of a portfolio you’re comfortable concentrating in a single stock and can still sleep at night. The term was coined by David Gardner, co-founder of The Motley Fool.

We polled nearly 300 HNW individuals and most said their sleep number is below 15%. 

More than a quarter said their sleep number is under 5%, likely reflecting a preference for broad diversification, often through index funds (e.g., Bogleheads). The largest group (33%) landed between 5% and 15%, with several noting they trim positions once they grow beyond this range.

At the furthest end of the spectrum, some founders and startup employees said they’re completely comfortable holding 50% to 90%+ concentrations.

While everyone’s sleep number is different, one theme stood out across our discussion: high concentrations can make sense when you’re investing in the right company.

The start of a new year is a natural moment to reflect on what matters most. We asked Long Angle’s HNW members what their 2026 New Year’s resolutions are focused on. 

Physical health and fitness topped the list, with 75%  including it in their resolutions. Family, friends, and relationships came next, highlighting a desire to maintain and strengthen connections. Some members said they’re specifically prioritizing in-person socialization this year.

Mental health and mindset, purpose and meaning, and time, lifestyle, and balance were each chosen by about a third of respondents. Together, they reflect a broader emphasis on quality of life and intentional living. 

Financial and career goals were less prominent themes, suggesting many are focusing more on life outside of work. Skills and hobbies were chosen by only a quarter of respondents, indicating many HNW peers are instead channeling their free time into health and relationships.
