Zeltiq Aesthetics Inc (ZLTQ), MAKO Surgical Corp. (MAKO) & Last Week’s Biggest Winners

What’s better than momentum? Mo’ momentum. Let’s take a closer look at five of this past week’s biggest scorchers.

Company Aug. 2 Weekly Gain
ZELTIQ (NASDAQ:ZLTQ) Aesthetics $8.23 34%
MAKO (NASDAQ:MAKO) Surgical $15.62 25%
Vical (NASDAQ:VICL) $4.81 21%
MercadoLibre (NASDAQ:MELI) $128.37 14%
Facebook (NASDAQ:FB) $38.05 12%

Let’s start with Zeltiq Aesthetics Inc (NASDAQ:ZLTQ). This is the company behind CoolSculpting, a machine that aims to freeze off the fat from those love handles. It may sound like a flaky idea, but a growing number of dermatologists, cosmetic surgeons, and dieticians have ordered the the machine and continue to use it.

Zeltiq Aesthetics Inc (NASDAQ:ZLTQ) surprised investors with a strong quarterly report, boosting its guidance dramatically for all of 2013. The company now sees revenue growing 20%, up from its earlier outlook of 10%.

MAKO Surgical Corp. (NASDAQ:MAKO)

MAKO Surgical Corp. (NASDAQ:MAKO) also moved higher after well-received financials. Sure, it did post a larger deficit than Wall Street was expecting, but the news on its RIO system was encouraging. MAKO Surgical Corp. (NASDAQ:MAKO)’s revenue rose 19%, but its procedure revenue climbed 26% during the period. In other words, orthopedic surgeons are using the robotic surgical system. Piper Jaffray raised its price target on MAKO Surgical Corp. (NASDAQ:MAKO) from $23 to $26 after the report.

Vical Incorporated (NASDAQ:VICL) posted another quarterly loss on light revenue, but investors aren’t looking at the upstart biotech’s past these days. Vical Incorporated (NASDAQ:VICL) is getting ready to report top-line results from its critical phase 3 study of its Allovectin vaccine’s ability to tackle melanoma.

Mercadolibre Inc (NASDAQ:MELI) moved nicely higher after delivering another strong quarter. The leading online marketplace operator through Latin America saw its revenue grow at a robust 40% clip. That’s caliente! Earnings didn’t grow as quickly, but the $0.67 a share it did earn was well ahead of the $0.62 Wall Street was targeting.

Finally, we have Facebook Inc (NASDAQ:FB) doing something that it hasn’t done in 15 months. The social-networking giant closed above its $38 IPO price on Friday. The only other time that happened was the day Facebook Inc (NASDAQ:FB) went public in May of last year.

Investors continue to hop back on to the dot-com giant after a strong quarterly report a week earlier. Facebook’s strength in monetizing mobile has turned last year’s IPO debacle into this year’s comeback kid.
