From tiny acquisitions to massive conglomerate combinations, Wall Street's urge to merge remains strong. Some of these deals might generate sought-after synergy, but others could create what Peter Lynch called diworsification -- weakening a business's core competency by grafting on wildly unrelated subsidiaries. How can we tell the good deals from the dealbreakers?

Breaking down the buildup
To help, we'll turn to the 97,000 investors in Motley Fool CAPS. Combining two companies with high CAPS ratings should bode well for the new firm's future results, while a high-rated company that joins a lower-rated one may benefit one set of investors more than the other.

Despite troubles in the capital markets, the deals won't stop; they simply might involve more stock and less cash. Here's a handful of recently announced deals, and the ratings for each participating company on CAPS' five-star scale:

A bear of a time
Although there seem to be a greater number of deals pending, the first quarter's $736 billion is the actually the smallest global dollar value amount in six years. The total number of deals is up 14% to more than 9,100 -- those deals are just worth less overall. This is primarily because of the 41% decline in U.S. deal values, down to $203 billion, though both Russia (up 173% to $33 billion) and China (up 43% to $35 billion) have made up some of the slack.

A scanner darkly
With Wrigley's getting chewed up by the Mars Bar, and Wendy's finally gaining the stomach to accept the bid Arby's pulled from its 10-gallon hat, the diversified Honeywell's purchase of bar-code reader MetroLogic seems quaint in comparison.

Yet the $16 billion industry is positioned for double-digit growth. Honeywell has been gathering a number of names in this sector under its umbrella, aiming to become a preeminent operator. MetroLogic brings with it some $246 million in annual revenue and a broad array of laser, holographic, vision-based, and RFID technologies. It's a small acquisition for a company with more than $35 billion in annual revenue itself, but the deal is in line with Honeywell's plan to make smart acquisitions in growth fields. Those purchases have helped Honeywell gain some 10% in value over the past year.

The company's well-diversified nature attracts investors in economically uncertain times. CAPS player BudandMolly, who has outperformed more than 80% of the 100,000-plus investors in The Motley Fool's investor-intelligence community, thinks its efforts in other sectors also help position Honeywell to weather any storms in the long term:

It is in two strong growth areas, aerospace and energy control. In spite of oil prices, aerospace will grow significantly over the next 5 years along with third world growth and the demand for new, more energy efficient aircraft will continue. The need for companies to be more green and control energy costs will also drive above average growth in their controls segment.
