A plain-language primer on public-market inputs that can converge on a Signa Action Card — and the limits that remain attached to every read.
The Signa method
Multiple inputs. One evidence trail.
Signa organizes market intelligence so the evidence stays visible alongside the decision.

Gamma describes how an option’s delta is expected to change as the underlying price moves. Signa uses gamma exposure as one view of the positioning environment around a setup; it does not turn a future price move into a certainty.

An options print becomes more legible when its strike, expiry, size, timing, and surrounding market state remain visible. Signa keeps curated flow beside the broader evidence trail, rather than presenting a single trade as a standalone conclusion.

Dark pools are alternative trading venues designed to help execute large blocks without broadcasting pre-trade order details. Listed-stock ATS trades are reported after execution, so the data can add context but does not reveal an order book or a complete thesis.

Forms 3, 4, and 5 report holdings and many transactions by officers, directors, and 10% shareholders. Signa presents reported activity as a research input; readers should review the underlying filing and transaction code before drawing conclusions.

This educational primer is not investment advice. It is a guide to reading information sources and their limits. Options involve risk and are not suitable for all investors.
