Net Share Issuance
Whether the company has been issuing new shares (dilutive) or buying back stock (accretive).
Formula
Year-over-year change in shares outstanding, sign-flipped (issuance reads bearish)
Interpretation
Companies that issue substantial new equity have historically underperformed those that buy back shares — issuance is often read as management signaling the stock is fairly or richly valued.
What good looks like
Share count flat or declining (buybacks).
What bad looks like
Meaningful share-count growth (dilutive issuance).
Typical range
Most established large caps sit within a few percent year-over-year.
Limitations
Issuance for a genuinely value-accretive acquisition or growth investment looks identical in this factor to issuance driven by weak fundamentals — it cannot distinguish the two.
How OmniSignal uses it
