Characteristic line

Graph showing the relationship between a security's returns and market returns.

Definition

Characteristic line is the graph showing the relationship between a security's returns and market returns. Founders reach for it when a vague conversation needs a shared, specific meaning. Name it clearly, then let the next decision — a hire, a price, a test, or a pass — follow from that meaning.

In the room

How the word shows up in a real conversation.

A mentor asks, “What is your Characteristic line?” The useful answer is concrete: graph showing the relationship between a security's returns and market returns. A slide title is not an answer.

Common mistake

Using Characteristic line as a label instead of a fact. If you cannot point to the evidence — a number, a customer, or a written assumption — you are using the word as jargon.
