How iesto works

iesto shows which US and Canadian stocks traded far more than usual in the last session, and puts the news that explains each move right next to it. AI stocks come first.

Unusual volume

A stock's relative volume is its trading volume divided by its average over the previous 30 sessions. 3.0× means three times a normal day. Heavy volume is usually the first sign that something happened: earnings, a deal, a filing, an analyst call. The list keeps stocks at 2× or more (1.3× for AI stocks, since giants like Nvidia rarely double their volume), and leaves out shares that trade less than $1M on an average day.

Funds, ETFs and Canadian depositary receipts are left out: they move with their holdings, not their own news. A company listed in both countries appears once.

The news

iesto reads the public feeds of BNN Bloomberg, Business Wire, CNBC, GlobeNewswire, Hacker News, Investing.com, MarketWatch, PR Newswire, SEC EDGAR, Seeking Alpha, TechCrunch, The Globe and Mail, The Verge. When several outlets cover the same event, it is shown once, with the number of outlets covering it. A mover's news is what was published between the previous session's close and the end of its own session. "No news found" is information too: volume without a headline.

Data delay

Market data is end of day and updates each morning before the open. Canadian sessions can appear a day later than US ones.

Not investment advice

iesto is an information service. Nothing on it is a recommendation to buy or sell anything. Headlines belong to their publishers and link to them.
