BlackBerry soared in its first week trading under its new ticker symbol and its first full week since leaving its Research In Motion moniker behind. The market's initial reaction to the smartphone pioneer's BlackBerry 10 unveiling last month wasn't positive, but opportunistic investors were snapping up the discounted shares this past week.

MBIA also moved higher. The financial-guarantee insurer rallied after a rival's lawsuit against a banker proved successful. The move opens the door for insurance guarantors to go after banking giants.

Sometimes all it takes is a big payout to get the market excited. Whiting USA Trust will pay a quarterly distribution of $0.577618 per unit next month. If the oil and gas partnership can keep that pace going for the balance of 2013, investors would be looking at a yield of more than 30%. There's no free lunch, of course. The units wouldn't be trading this high if the market thought the heavy payouts would be sustainable.

3D Systems bounced back after losing ground a week earlier. The additive manufacturing niche leader kicked off the week by announcing the availability of a 3-D reverse engineering and design tool for portable scanners that's powered by its Rapidform platform.

Shares of Sequenom have closed higher in six of the past seven trading days. On Monday, Sequenom announced that its flagship genetic maternity test will now screen for the presence of certain fetal sex chromosomal aneuploidies.
