DAYTON — Shares of Teradata Corp. rose 3.4 percent Friday following website speculation that Mark Hurd, the former head of Hewlett-Packard Co., would return to Teradata.

Shares of Teradata (NYSE: TDC) closed Friday, Aug. 28, at $32.46, up $1.07. Trading volume was 2.5 million shares, compared with the average 1.8 million shares. Teradata’s share price started rising Thursday after TheFlyOn

TheWall.com, a subscription-based market news site, speculated that Hurd could return to Miami Twp.-based Teradata. Hurd ran Teradata when it was a division of NCR Corp. Hurd left NCR in March 2005 after two years as the company’s CEO to take a similar job at Hewlett Packard.

Hurd resigned from Hewlett-Packard Aug. 6 following an investigation into a sexual harassment claim that found violations of the company’s “standard of business conduct” policies, the Palo Alto, Calif.-based company said. HP’s board appointed CFO Cathie Lesjak, 51, as CEO on an interim basis.

Barron’s Online reported what TheFlyOnTheWall reported and added: “It would be a little hard to imagine Hurd going to Teradata to run a division; ergo, you have to wonder how this theory makes Teradata CEO Michael Koehler feel; he’s had the company’s top job since it was spun off from NCR in 2007.”

Teradata declined to comment on the online reports.
