When to use this metric
Read the explanation first. Then use the ranking to compare the signal across assets.
Momentum (12–1 months) is most useful when you need to judge whether an asset is participating in a persistent move rather than only bouncing short term.
This trend lens translates momentum, relative leadership, and technical confirmation into a clearer signal for current ranking quality.
Use it when you want to separate a durable leadership move from a noisy bounce that may look strong only in hindsight or over a short window.
Start with the calculation and interpretation, then compare the ranking and the adjacent trend views to test how durable the move looks now.
Read the definition, sources, calculation, and interpretation after the ranking above.
Momentum (12–1) is a classic “tailwind” metric: it looks at the past 12 months but intentionally excludes the most recent month.
Why? Over a one-month horizon, a few days (earnings, macro news, sentiment) can dominate. Excluding the last month is commonly used in studies (“12–1 momentum”).
Depending on the market we approximate ~252 trading days (stocks/ETFs) and then skip about 1 month (~21 trading days or ~30 calendar days).
