Stonder for media companies

About Stonder

Stonder is a platform for aggregating the collective intelligence of investors by crowdsourcing investor sentiment. Stonder does this by collecting investor opinions – Buy-Hold-Sell – on individual stocks from a large, diverse user base.

The opinions are aggregated with an algorithm to a user consensus estimate on each individual company. This opinion is called Rating. The Rating for each company is displayed in a list format.

Stonder Sentiment shows the relative attractiveness of a company’s current Rating in relation to its Rating history. Sentiment visualises current change in a company’s Rating. Rating and Sentiment are the key metrics Stonder provides to users.

Stonder has gathered some 600 000 opinions on Nordic stocks from users as of September 2017

Stonder dataset is not available elsewhere. The unique content has proven to increase reader session duration on stock market pages. Page heatmaps show that Stonder content is actively used.

The media dashboard highlights “opinion movers” and can be used to generate ideas for articles.
