Bear Case

Builds the strongest case against, and names the way the trade breaks.

Why the desk needs it

The costliest mistakes come from not taking the downside seriously. The Bear Case exists to answer one question with evidence: if this trade fails, what is the most likely reason? If the thesis can't survive that prosecution, you shouldn't be in it.

What it reads
All four desk reports

The same evidence base as the bull - mined for fragility instead of promise.

Valuation tolerance

How much perfection the price already assumes, and how little disappointment it can absorb.

Crowding & narrative excess

Where consensus is so one-sided that a small miss gets amplified.

How it thinks
Attack the strongest version

Refuting a strawman proves nothing; it argues against the bull's best case.

Asymmetry over pessimism

The dangerous setups aren't bad businesses - they're high expectations with no room to miss.

Name the failure path

Every bear argument maps to a specific, watchable way the trade breaks.

What it hands off
The bear thesis

Why the stock may be overpriced, fragile or misunderstood - cited like the bull's.

A failure map

The specific variables most likely to break the trade - later fed to Thesis Watch.

Downside scenarios

What the Risk Committee stress-tests and Trade Structuring stops against.

What it does not do

The more specialized a role is, the more clearly it has to know its boundary - overlap is where black-box answers come from.

Its output appears as a named section in every report - with the rest of the desk arguing around it.
