Independent by design, since 2002.
Main Management is a partner-owned investment manager in San Francisco — one of the early pioneers of ETF portfolio management — serving advisors, institutions, and families with the same discipline and the same white-glove service since the day the firm opened.
Since 2002
The firm, built through every cycle.
Two decades of strategy launches, ETF listings, and milestones — hover the line to trace the firm’s asset growth, quarter by quarter.
Founded in San Francisco
Three industry veterans open Main Management to build ETF-based portfolios for families, foundations, and advisors. The firm’s first active strategy launches the same year — GIPS-verified from the start.

The discipline
One process, refined through every cycle.
Everything the firm manages runs on the same framework: fundamental, with a catalyst. It comes down to two questions every position has to answer — valuation tells us where to look, and a catalyst tells us when to act.

Valuation-driven entry
Don’t overpay. Every position begins with what it costs relative to its own history and its peers — what’s attractive on fundamentals before anything else.
- When to act
Catalyst-aware timing
Cheap alone isn’t a thesis. There has to be an identifiable reason the market will close the gap — a catalyst we can point to.
The service ethos
When you call, we answer.
White-glove service isn’t a tier here — it’s how the firm has worked since 2002. The people who run the strategies are reachable, and the relationship is the product.
Reachable decision-makers
When a question needs the investment committee, you talk to the investment committee — not a layer of gatekeepers.
Proactive when it matters
In volatile markets the communication comes to you — context and positioning before your clients call, not after.
A resource for the whole practice
Research help, portfolio reviews, and model construction across your book — not just the slice Main manages.
Come see how we work.
Twenty-four years in, the front door still works the same way: call, and someone who manages money answers. Tell us about your practice and we’ll take it from there.
