"3-mo price move" is the stock's market price change, not a FrontierPicks return. The "3-mo price move" column is one of the three inputs to that score, weighted 20% — not the ranking itself, so rows do not descend in it. A dash means the name did not place in this week’s top-50 momentum scan, so it has no published 3-month figure.
How this page is built
These are the names FrontierPicks covers in the optical networking stocks theme, each with a dated research dossier. Names on the momentum board rank first by a composite momentum score — 1-month price trend 50%, 3-month trend 20% and acceleration 30% — computed arithmetically from daily closing prices, through the last completed session, then the rest by conviction. The research decides which stocks belong to each theme; this one currently reads as maturing.
