Martinus (Martijn) Rats & team Morgan Stanley

The buy side says: “The team has written very timely sector reports with interesting analyses, highlighting important topics ahead of everyone else.”

Martinus (Martijn) Rats, 38, leads the two-member Morgan Stanley duo to a first-place debut in this new sector. (Oil Services and Oil & Gas Exploration & Production were broken out this year from the former Oil & Gas sector.) The analysts, who win praise from one money manager for being “more insightful and forward-­thinking than their competitors,” upgraded Petroleum Geo-­Services from underweight to overweight in August 2009, calling shares of the Lysaker, Norway–based seismic-­studies provider a bargain at 43.12 Norwegian kroner. In May, after the stock had climbed a whopping 84.3 percent, to Nkr79.45, and bested the sector by 57.7 percentage points, they downgraded it to equal weight, on valuation. By the end of the year, it had climbed to Nkr90.85, gaining 14.3 percent but lagging the sector by 17.8 percentage points. Rats earned a master’s degree in physics at the Netherlands’ Delft University of Technology in 1996 and a master’s in finance from the London Business School in 2001; he joined Morgan Stanley the following year.
