Momentum

Each signal is ranked as a percentile among the technologies that have it. A signal without enough history is not counted, and never shown as zero. How momentum works

Momentum

Collecting1 of 5 signals

No score yet. Momentum is published only when at least 2 of the 5 signals have history. Jest has 1, so there is no single number: each signal is shown on its own below. It is not a zero, and nothing is estimated in its place.
