Market Screening & Ranking Terms
Before drilling into a single ticker, most sessions start with a wider question: where is the action right now? These four terms cover the terminal's answer to that, across four different tabs and four different scopes, from a whole-market color grid down to a single ranked list of managers by size. Each one flags where attention or size is concentrated. None of them explains why it got there.
Sector heat map / treemap
A sector heat map, sometimes called a treemap, lays out every sector or theme as a box sized by its weight in the market and colored by how much it moved today, usually green for gains and red for losses, with shade intensity tracking magnitude. The layout turns a whole market's worth of individual price moves into a single glance: which parts of the market are leading, which are lagging, and roughly how broad or narrow that split is, without scrolling through dozens of separate percentage figures. It's a snapshot of the current session, not a running history, so a sector that heat-maps green all morning can flip red by the close, and the map itself resets with each new session rather than carrying yesterday's color forward. It also groups by traditional sector classification, which means a stock straddling two industries only shows up in whichever bucket it's been assigned to.
Concept / theme plate
A concept or theme plate groups stocks by a shared narrative, like AI infrastructure or semiconductor supply chains, that cuts across the standard sector classification a heat map uses. Two companies can sit in completely different official sectors, one in technology and one in industrials, and still belong to the same theme plate if the market currently trades them together on the same story. That's the gap this view is built to close: a sector-only read can miss rotation that's really happening at the theme level, where a handful of stocks across multiple official sectors move together because investors are treating them as one trade. Theme membership is also less fixed than sector classification. Themes rise, fade, and get redefined as market narratives shift, so which stocks belong to a given plate today may look different from how it was defined a year ago, in a way official sector codes don't.
Hot List / heat score
The Hot List ranks tickers by a composite of trade activity, search interest, and news attention, producing a relative "how hot right now" read rather than a price or dollar-volume figure. A stock can rank high on the list without being a top mover in either price or dollar volume that session, if it's drawing an outsized amount of attention relative to its own normal baseline. That relative framing is also the list's main limit: it says a name is unusually active or talked about right now, not why, and not whether that attention reflects real new information or is simply carrying over from a story that broke a day or two earlier. The ranking also reshuffles constantly through the session as underlying activity changes, so a name's position on the list is a snapshot of this moment rather than a settled read on the stock. It works best read alongside a reason, since a jump in heat score paired with a specific catalyst is a very different situation from the same jump with no news attached.
Top Institutions leaderboard
The Top Institutions leaderboard ranks institutional managers by total assets under management, a pure size cut of the institutional universe that's separate from the buy-and-sell activity rankings found elsewhere on the same tab. A manager can sit near the top of this leaderboard purely by virtue of running a large, stable book, with a given quarter showing very little actual buying or selling activity at all. Size and activity are two different lenses on the same underlying 13F data, and this leaderboard deliberately isolates the first one. Because it's sorted by AUM rather than by how much a manager's positioning changed, it's the wrong place to look for which funds are moving fastest right now. It answers who the largest players are, not who's currently the most active, which is exactly the question the tab's other ranking views are built to answer instead.
