Hedge fund
Get faster reads on the names you trade, with the evidence and the counter-argument kept right alongside them.

What the job asks of you
A fundamental long/short book rewards being right before the market is, and being honest with yourself when you are wrong.
More names than hours
Your universe is far wider than the handful of names you can know deeply, and the next idea is usually in the part you have not had time to read.
News on its own clock
Results, filings and headlines land at all hours, and the first question is always the same: does this change the thesis?
Conviction that has been tested
Sizing a position takes more than a good story. It takes the other side argued properly, before the market argues it for you.
A working day with Cairn
From the first headline of the morning to the decision on size, each step has a part of Cairn behind it, and the call stays yours.

How it fits your business
How your business works
A hedge fund is paid largely for performance, so the value of research shows up in the quality of its calls and in how quickly the book responds to news. People and data are the main costs, and an analyst's hours are the scarcest input of all.
| What your business needs | What Cairn changes |
|---|---|
| Wider coverage without more analysts | Each name you follow keeps a case file that agents bring up to date, so one analyst can keep many more names in view. |
| A faster response to news and results | News AI reads the wire for your book, and after each earnings release the questions it touches are reopened and researched again. |
| Calls you can defend and review | Each thesis keeps its sources, its earlier versions and the counter-argument, so you can see why a call was made long after you made it. |
