Market Breadth Today: Stocks Above Their 200-Day Moving Average

The share of valid covered stocks above their own MA200 at each recorded date. The lower line shows the sample count; dashed markers indicate changes of at least 20% in that count.

Changing coverage can move the percentage without a comparable market move. A stable count alone does not prove identical membership. Breadth lines are broken at large count changes.

Common questions

What is market breadth?

Market breadth measures how many stocks are taking part in a market move, rather than how far an index has moved. An index can rise on the strength of a handful of large companies while most stocks go nowhere; breadth shows whether the advance is broad or narrow. A rising index with falling breadth is the classic sign of a narrowing rally.

What are the common market breadth indicators?

The percentage of stocks above a moving average (the 200-day for the long-term trend, the 50-day for the intermediate one), the advance-decline line, new highs versus new lows, and the up-volume versus down-volume ratio. This page tracks the first: the share of covered stocks above their own 200-day moving average.

What does "percentage of stocks above the 200-day moving average" mean?

It is the share of a defined group of stocks whose latest closing price sits above the average of its own last 200 daily closes. It is a breadth measure: it counts how many names are participating in a move rather than how far an index has travelled.

What counts as a high or a low reading?

A larger percentage means more of the covered stocks are above their own long-term average. Interpretation depends on the stock pool, sample count and date. This page does not turn the reading into a reversal forecast or rank it against history with unverified comparable membership.

How often is it updated?

Once per trading day, after the close, from the same nightly scan that produces the deviation rankings. The snapshot date shown is the data's date, not the date the page was rendered.

Is this the same as the S&P 500 being above its own 200-day average?

This page counts individual stocks in our covered pool; an index level measures a weighted basket. They answer different questions. Our pool is combined coverage, so its percentage should not be labelled as official S&P 500 or Nasdaq 100 breadth.
