Tuesday's Late Winners & Losers

The most heavily traded stocks were on the upswing after the bell Tuesday, and leading the charge was Cisco Systems (CSCO Quote).

The San Jose, Calif., networking-products giant surged 5.4% to $31.28 after CEO John Chambers issued bullish fiscal first-quarter sales guidance of $9.45 billion to $9.55 billion. Analysts polled by Thomson Financial are looking for $9.38 billion. The company also posted better-than-expected fourth-quarter results for both income and revenue.

Elsewhere in tech, discount-travel Web site Priceline.com (PCLN Quote) leapt 9.2% after doubling its second-quarter pro forma profit to $1.11 a share, which blasts past Wall Street's 89-cent expectations. Shares of the Norwalk, Conn., company were up $6.01 to $71.10.

Perini (PCR Quote), a construction company based in Framingham, Mass., ballooned more than 16% after shattering per-share estimates by 40 cents with second-quarter earnings of $27.6 million, or $1.01 a share. Outsourcer PeopleSupport (PSPT Quote) reported earnings of 16 cents a share in that quarter and authorized the repurchase of up to $25 million of its shares. The stock traded 11.1% higher to $10.71.

On the flip side, Heelys (HLYS Quote) shares took a postbell beating after the Carrollton, Texas, company sharply lowered its fiscal 2007 year-over-year growth forecast to range between 10% and 15% (for both top and bottom line) compared with the prior 20% to 25%. That translates into sales of $207 million to $216.43 million, or at least $56 million short of the Street's consensus. Shares of the company, which primarily makes sneaker-skates with retractable wheels, plunged 33.6% to $14.60 in spite of better-than-expected results for the second quarter.

Leap Wireless International (LEAP Quote), meanwhile, more than halved its per-share earnings to a nickel. That topped second-quarter estimates by a penny, but the San Diego company's $393.2 million revenue fell short of the $408.1 million mean target. Shares of the wireless-services company were losing $11.12, or 13.8%, to $69.24.
