Advancing/Declining (Post)

Overview​

The Advancing/Declining (Post) profile carries the breadth view into the after-hours session. The market is split into advancing and declining stocks and each box is colored by the combined change from the previous close including post-market movement, so a stock that reversed its daily move after the bell is shown where it truly stands.

It answers the evening question the closing print alone cannot: is the after-hours action confirming the day's breadth, or quietly undoing it?

info

This profile updates in real time throughout the post-market session as after-hours trades come in.

Strategy Focus​

  • Read breadth after the close, including earnings and news reactions
  • See whether after-hours moves confirm or reverse the regular session's balance
  • Spot clusters of post-market weakness or strength that hint at tomorrow's open
  • Track how the day's final advance/decline picture settles before the next session
  • Find liquid names still moving after hours for next-day preparation

Map Configuration​

  • Main Category: Advancing/Declining
  • Box Size: Average Turnover 3 Months ($)
  • Box Color: Change From Close + Post (%)

Metrics Behind the Map​

  • Advancing/Declining: Splits the market by whether a ticker's last price is above (advancing) or below (declining) its previous day's close.
  • Average Turnover 3 Months ($): The three-month average daily turnover, calculated as price times volume, keeping the most tradeable names visually dominant.
  • Change From Close + Post (%): The combined percentage change from the previous close including post-market movement, so the color reflects the true net position after hours.

Practical Use Cases​

  • Run an evening breadth check before finalizing plans for the next session
  • Watch how earnings season reshapes the balance night by night
  • Spot names that flipped camps after the close and investigate why
  • Build a next-morning watchlist from liquid after-hours movers
  • Compare against Advancing/Declining (Reg) to measure how much the after-hours session changed the picture
