) is finally catching up with its peers. Since mid-August, the stock has risen from 23 to 36. Still, shares of the world's largest offshore driller -- mainly deepwater and harsh-environment drilling -- are up a mere 6% since 1999, while the broad oil-service index OSX has doubled. Why? Until recently, "most major oil companies were forecasting oil prices would settle at around $20 a barrel," says Stephen Leeb, president of Leeb Capital Management, which owns shares. At that price, the more expensive deep-sea drilling is marginally profitable at best, he notes. With oil now about $55 a barrel, Transocean, which controls some 40% of deepwater oil drilling rigs, is starting to get orders, says Leeb. Low demand had discouraged rig builders from investing in new ones, and now "there will be a scramble for the few offshore rigs available," says Leeb. He says day rates are rising, which should mean "fat profits for Transocean." His 24-month stock price target: 60 to 65. He estimates earnings of $2 a share for 2005 -- way up from the Street's consensus of $1.07 -- and $4 in 2006, vs. the Street's $2.
