MAR compliance for small funds with no dedicated compliance team
Last reviewed 23 June 2026.
A small fund doesn't get a lighter MAR obligation -- it gets to meet the same obligation with less headcount, by automating the part that doesn't need a person and reserving human time for the part that does.
The three parts of a minimal-but-real setup
- Automated daily detection on the fund's own trades for the common patterns: informed trading (a trade just ahead of an unexplained price move in the same direction), off-market pricing (a fill detached from the day's range without justification), and unusual volume (a trade representing an outsized share of average daily volume).
- A documented review step -- one compliance officer or MLRO looks at whatever the detection step flagged, decides whether it meets the "reasonable suspicion" bar for a STOR, and records that decision, even when the decision is "no filing needed."
- An audit trail -- a dated record that surveillance ran on every business day, what it checked, what it found (or didn't), and how each alert was resolved. This is what a regulator or auditor actually asks to see; "we were watching" on its own isn't evidence.
Why "we'll do it manually for now" doesn't hold up
Manual review scales with headcount; a single person scanning a daily trade list for patterns will miss subtler cases (a trade that's only suspicious once you compare it against 90-day average volume, for instance) and won't produce a consistent audit trail. The fix isn't more people -- it's moving the pattern-detection step to something that runs the same way every day and only asks for human time when there's an actual judgment call.
