Independent Investment Fund

RBA Equity

Independent investment fund focused on identifying short-term mispricings, opportunistic market sentiment, and an expectation-driven philosophy across micro and SMid-cap technology equities. RBA Equity is primarily focused on developing investment judgment, idea generation, and analyst development through real-world investing experience and allocating real capital.

Our Story
The history of RBA

RBA stands for "Research by Aidan" and was initially created when I began doing my own equity research. It later pushed me to pursue a career in equities and investing.

I recently made the decision to mentor fellow students who are curious about a career in finance, and to further build my investing track record by creating this fund. This summer, RBA Equity has four ambitious analysts:

Active Coverage

Research

A collection of our positions. Memos will be published within one week of trade date. While portfolio performance has been strong since inception, results have also benefitted from a bull market, favorable market environment, and overall strength in tech equities. RBA Equity places a greater emphasis on developing a repeatable process instead of returns.

Pre-Fund Coverage

Archived Research

This is past research that was internally stored and is now being publicized. It contains backwards-looking information created prior to the founding of RBA Equity, and also includes two pitches from my school investment fund, MAIF (Minutemen Alternative Investment Fund). There is no fund capital behind these names; returns shown are tracked from the entry price stated in each memo to the most recent close, for reference only.

Lessons & Review

Post-Mortems

Notes that describe what we got right and wrong, an honest assessment of thesis accuracy, and the reasoning behind our decision to buy, hold, or sell each position. Post-mortems are where the process gets sharpened. They matter more to us than the returns themselves.

No post-mortems published yet
Our first post-mortem will appear here once a position is closed or materially reassessed. Check back soon.
The People

Our Team
