The trend scores falling fastest
The stocks whose trend score dropped the most over the last 21 trading days — where leadership tends to break down first.
The mirror of the “rising fastest” list: the scores that dropped the most over the last 21 trading days. A falling score means the trend is losing quality — leaders that stop leading tend to appear here before it is obvious on the chart.

FAQ
What is the Directional Flow score?
A number we compute every night for every stock we cover. It measures how steady and reliable the stock’s price trend is — most stocks score below 100, and only exceptional trends go far above it. A high score means the stock has been moving in one clear direction, in an orderly way. It grades the quality of a move, not just its size.
How often is this ranking updated?
Our engine runs after every US market close. This page is rebuilt every morning with the fresh ranking, and it always shows the date of the scan it was built from.
What do the 5-day, 21-day and 63-day columns mean?
They show how much the score itself has changed over roughly one week, one month and one quarter of trading days. A rising score means the trend is getting stronger; a falling score means it is getting weaker.
