How is buy-side different from sell-side research?

Buy-side is internal, uncompromised by external publication conflicts, and measured by investment outcome. Sell-side is published externally with disclosed conflicts.

What's the typical buy-side research budget?

Varies dramatically by fund size and strategy. Hedge funds: mid-six to seven figures annually. PE funds: spend per deal, typically €50-200k per major transaction.

Where do expert networks fit?

Buy-side teams use networks for operator-level primary research that complements databases and sell-side coverage. Typical 10-20% of research budget on networks.

Buy-Side Research

Buy-side research is internal investment analysis conducted by hedge funds, asset managers, PE firms, family offices and other allocators for their own use. Distinct from sell-side research, which is externally published.

01/In Depth3–5 paragraphs

Buy-side research is uncompromised by the conflicts that affect sell-side coverage. Internal analysts produce thesis-driven work that's measured by investment outcome, not analyst-of-the-year ranking.

Buy-side teams use a layered research approach: secondary research (databases, sell-side, analyst reports) for context; alternative data (channel checks, surveys, satellite imagery) for differentiated signal; expert-network primary research for operator-level depth.

Expert networks are particularly valuable for buy-side research because they enable the buyer to test their thesis against operator reality without disclosing the thesis or the buyer identity to the operator.

Typical buy-side research cost structure: 30-60% spend on data subscriptions; 25-40% on alternative data; 10-20% on expert networks. Mix varies materially by investment style.
