Over on CAPS, fully 900 of the 945 members who have rated Cummins -- some 95% -- believe the stock will outperform the S&P 500 going forward. These bulls include OleDrippy and jirvineuk.

Last week, OleDrippy stated a simple bull case for Cummins: "Best of breed, taking over CATs market share, been obliterated along with the rest of the market... Has a lot of upside potential when investors flock to companies who make 'stuff.'"

In a pitch from one week earlier, jirvineuk agrees, elaborating on rival Caterpillar's departure from the playing field. Here's an excerpt:

Their largest competitor in the diesel engine business was Caterpillar, who recently announced that they were abandoning the loose engine market. Leaving Cummins to gobble up their 25-30% market share. So Cummins sales and profits are doing well and as they take over more of Caterpillar's business, they have built-in growth potential. There's no reason for their stock to be down to half of their "normal" price other than lots of money leaving stocks for "safer" investments. ... Due to the economy, you can expect durable goods to decline for the next several months. But Cummins will be less affected by this due to taking over the Caterpillar markets.
