To us at XBRL International it’s clear that XBRL data enables better decision making and offers value to investors and users of all kinds. Supporting that assertion is a point-of-view post at XBRL US, in which Steven Huddart of the Smeal College of Business at Penn State University asks “Are XBRL data better at predicting future stock returns?”

The article covers research conducted by the Penn State team comparing XBRL data (as provided to the Securities and Exchange Commission) and normalised commercial data in predicting accounting anomalies, which investors can utilise to their advantage. They found significant discrepancies between the as-filed and the commercially processed data, particularly for firms that are smaller or are experiencing higher growth.
