When looking at the data in rezora's Market Reports, the real time market profile notes the 7-day for each of those statistics. The chart will show both the 90 day and 7 day. Altos Research data is updated weekly over the weekend. The best bet would be to rely on the update having been completed by Sunday morning. When it comes to listing Altos Research only focuses on 100% active so their "Inventory" count will reflect that and not include pending.
The Data - Altos has a proprietary database and market analytics system that they use to prepare the market reports. While they don't disclose the specifics on how their analytics technology works, the thing to understand is they obtain their data from multiple sources including off market. There are a few key things to be aware of that makes their data a bit different than direct from your MLS. They focus on 100% active market. Absorbed is commonly referred to as “Sold”. Their "absorbed" refers to anything that differs from that 100% active state (i.e. pending, expired, removed). Things like DOM, they do active to “absorbed” (absorbed on their terms). They also provide both a 90-day average (trend) and 7-day average that may differ from what a single source provides.
Real Time Market Profile – provides the most recent data from previous week. In addition to the data presented you’ll find spark lines (tiny charts) that provide a trend over the last 3 months so you can see how things may have changed.
Market Action Index: The MAI is the Market Action Index, their proprietary algorithm. The MAI is the thermometer of the market, the higher the number the hotter the market. It answers the question, "How's the market?" by measuring the current rate of sale verses the amount of inventory. With 30 being the base, neither buyers market nor sellers market, when the index goes above 30 it implies a sellers market. Below 30, conditions favor the buyer.
Market Segments: With the segments they take all the active listings and list them from most expensive to least expensive. They then divide that by 4 so that each segment has the same amount of inventory (combine the inventory for each quartile and it will equal total inventory for said area). The "New" is any new listings over the last week. The "Absorbed" is anything that is no longer 100% active (i.e. pending, sold, expired, removed and etc.).
