Datum Inc. Stock Rises 18% After Receiving ‘Buy’ Rating

Datum Inc. stock, which has been taking a beating in recent weeks, climbed nearly 18% Monday after an analyst upgraded his rating of the shares.

Datum shares rose by $2.44 to $16.19 on the Nasdaq market after the company, which makes equipment that tracks information in phone networks, was raised to “buy” from “neutral” by analyst Vincent Glinski at Rodman & Renshaw Inc.

The stock traded as high as $49.50 in September before hitting the skids when the company reported lower-than-anticipated quarterly earnings because of a customer’s change in buying practices and a slowdown in construction of wireless phone networks. The stock fell to a 52-week low of $12 earlier this month.
