Does it explain pre-market and after-hours moves?

Yes. It explains the latest price move, including pre-market and after-hours moves.

What sources does it use?

The company's news and press releases, its earnings release and recent filings, and news on its sector, peers and the wider market. It also reads links and documents you add to the run, and any internal sources you expose through Connectors, such as research notes or broker research.

Can it use flows and fund positioning?

Yes, if you have a supported data source added through Connectors. Without one, it explains the move from news, earnings, filings and same-session sector and peer moves.

What happens when it cannot find a cause?

It checks for a same-session sector move or a larger move in a peer and names it if there was one. Otherwise the report says the cause is unclear.

Can I schedule Why's It Moving?

No. It runs on demand, since its job is a first read on the move in front of you when you start it.

Why's It Moving is a new Deep Research Agent that tells you why a stock is moving. Choose a company and it explains the latest price move from the company's news, its earnings release and recent filings, and from what happened to its sector and peers in the same session. If you have a supported data source added through Connectors, it can also draw on flows and fund positioning.

When to Run the Agent

The agent is built for the morning a stock on your watchlist is down 5% and you don't know why yet. Or for when your PM asks why a name at the edge of your coverage just had a big day. It is quick and to the point, giving you a first read of the story that you can then investigate further if the move warrants it.

What It Reads

On each run, the agent collects at least:

The company's newsflow and press releases
Earnings releases and recent filings
News on its sector, its peers and the wider market, as the move requires
Flows and fund positioning, if you have a supported data source connected

It also checks internal sources you expose to it through Connectors, such as your own research notes and broker research.

Add your own links and documents

The Why's It Moving run dialog with Nike selected as the company, one investor relations link added and an upload area for the user's own documents — Starting Why's It Moving with a link to read on that run.

When you start a run you can add up to five links for the agent to read on that run, such as an investor relations news page, a regulator's notice or an article you have already seen. It also reads the documents you have uploaded for the company, and you can upload more from the same dialog. The agent still runs its own search alongside your sources.
