Over on CAPS, 2,490 of the 2,538 members who have rated National Oilwell -- or 98% -- believe the stock will outperform the S&P 500 going forward. These bulls include mitleg and Northville.

In January, mitleg highlighted the stock as an attractive turnaround opportunity:

Very solid oil play. They have low debt and a solid book of business. P/E, peg, price to book, etc. are all attractive. ... I think things will ease up in the second half of 2009, but not dramatically. Buy for the long term.

In a pitch from last month, Northville cites National Oilwell's dominance as reason to bet on that bounce:

This is a large industry consolidator with little debt and a record backlog to work through while the rest of the industry and the supply/demand equation balances itself out. It is so dominant that something like 88% of the world's rigs have at least some [National Oilwell] components to them. It's P/E and ROI will never be as high as the smaller competitors in the industry due to [National Oilwell]'s sheer size, but it will certainly beat the S&P.
