Hedge Funds interview preparation
Long-short equity, macro, event-driven, distressed, multi-manager platforms and the Indian Category III landscape. Every question is either traced to a named firm from a public candidate report, or tagged at desk level when we could not trace it — answers lead with the point, then the mechanism, then the limitation.

045How do you attribute a fund's P&L?Multi-manager platformsRisk management
Say this
Split it into the pieces that correspond to decisions someone made. Market, sector, style factor, then idiosyncratic stock selection, then financing and trading costs. The residual after the systematic pieces is the only part that is evidence of skill.
Then walk it
- Start with market: beta-adjusted net exposure times the index return. That is the part you would have earned with no stock selection at all.
- Then sector or industry: the net weight in each industry times that industry's return relative to the index. This catches the PM who is really making a sector call and calling it stock picking.
- Then style factors from the risk model: growth, value, momentum, size, quality, volatility. Each has a net loading and a factor return, so each has a P&L line.
- Then the residual, which is stock selection. Split it long and short, because a book that makes all its money on the long side in a rising market has not demonstrated a short-selling capability and that matters for how much gross it should run.
- Then the costs that are frequently ignored: borrow fees, dividends paid on shorts, financing spread on the leverage, and realised trading cost. On a 300 percent gross book these can be well over a hundred basis points a year.
- The caveat to state: attribution is model dependent and the pieces do not add up cleanly. There is always an interaction and residual term, factor returns are estimated, and a PM can dispute the classification of a name. So I would use it to ask questions rather than to settle them.
Where candidates lose it
Attributing to positions rather than to risks. Listing the top five winners and losers is a P&L report, not an attribution. The point is to isolate whether the money came from decisions the PM is paid for. Remember to include financing and borrow costs; candidates almost always leave them out and they are large on a levered book.

Firm tags come from public, anonymous candidate reports on Wall Street Oasis: strong signal, not sworn testimony. Firms are named as the places a question was reported, not as partners of Fin Maverick. Answers are written for this page to show how to think out loud; they are not scripts to recite.
