Saying No To Money

The advice nobody gives a trader chasing their first capital allocation: some of the money you will be offered is worse than no money.

The short version
Saying No To Money cover image

When you are starting out and someone wants to put capital behind you, every instinct says yes. Eventually, you will need to learn how to slow that instinct right down, because the structure of a deal matters just as much as the size of it.

Why would you ever turn down capital?

Because capital comes attached to terms. An allocation that forces you past your strategy's real capacity for minimal fees, or pushes you into instruments you have no edge in, or carries a fee and lock-up structure that punishes you for the drawdowns you know are coming, is a liability you are being paid too little to carry.

What I actually check before saying yes

Three things, in order.

Capacity. Does this size sit comfortably inside what my strategy can absorb without the costs eating the edge, or does it force me to trade bigger than the edge supports? Capacity is a real constraint and the first thing people sell too cheap. Make sure you are getting paid enough in fees. Your capacity is your product. Do not sell it too cheap.

Mandate fit. Does taking this money make me change what I trade or how I trade it? If the answer is yes, the deal is buying me outside of my expertise.

The downside terms. What happens in a drawdown, because there will be drawdowns, and a structure that is punishing for slow periods can be seriously detrimental to your performance and motivation.

The mistake I see traders make

They treat the first yes as validation and accept terms they would never accept later, once they have leverage. The trouble is that the first deal sets the precedent for every conversation after it.

The first deal sets the precedent for every conversation after it.

Price your capacity too low to land the allocation and you have told the next allocator what you think you are worth. Accept a structure that punishes normal drawdowns and you will end up managing to the structure instead of the strategy, which is how good systems get interfered with to death.

What good actually looks like

The size fits inside your capacity with room to spare, so the costs do not move.

The mandate is the strategy you already run, unchanged, because that is the thing they are buying.

The terms assume drawdowns happen and do not penalise you for the normal ones.

And the investor understands they are buying a process, so they will not panic and pull at the first red month and force you to trade scared. That last part is worth more than a few basis points on the fee.

The cleaner way to think about it

An allocation is a relationship with a cost structure. The right ones pay you fairly for capacity you genuinely have, leave your mandate alone, and are built to survive the drawdowns that are coming.

I would rather wait for a deal that fits than take one that makes me a worse trader, because the whole point of the track record is that it is mine and it is clean. Selling that cheaply to start faster is the one shortcut that actually sets you back.
