Meet Synanthem Capital

We believe investing should be thoughtful, intentional and grounded in value discovery.

We believe investing should be thoughtful, intentional and grounded in value discovery.

The wait is part of the work.

The market has learned to price businesses by size. That distortion is why we were built for.

Few positions, by design.

We hold a small number of businesses we can explain in plain words, and we insist on a wide gap between price and value before we buy.

Risk is money lost for good.

Prices move every day and we treat that as weather. The risk we manage is paying more for a business than it turns out to be worth.

How we think

What we do while we wait

Genuine discounts appear rarely. Cash held for those moments is a deliberate position, and we put it to work in three ways.

A business at a discount

When a company we understand trades well below its worth, the reserves become a position. That is the moment the other two exist for.

Income from options

We write conservative options against those reserves. Someone pays us a premium for a commitment we are glad to make.

Interest on cash

Reserves sit in money market instruments and earn what the market pays for safety, ready to move within a day.
