What to Expect From Cisco Earnings
What to Expect From Cisco Earnings:
Cisco Systems Inc. (NASDAQ: CSCO) is scheduled to report its fiscal fourth-quarter earnings on Wednesday. Thomson Reuters Consensus estimates call for $ 0.56 earnings per share (EPS) of $ 12.65 billion in revenue. In the same period last year, the networking giant posted an EPS of $ 0.55 and $ 12.36 billion in revenue.
First, 24/7 Wall St. has selected Cisco as October 1 Stocks in possession for the next decade.
This company needs storage, and for years the same talk Wall Street is the company that the networking giant might consider taking a shot at. Some also believe that the company also focuses on software and cyber security and FireEye said was being examined in the spring, the rumor that Cisco denied. However, Cisco is now under a new CEO and the company has shifted.
This is the first mega-cap technology picks stocks on Wall Street, and perhaps a surprising defensive option. Cisco Systems is trading at an estimated price of 12.9 2015 earnings. The networking giant also seems to have fought for many headwinds, including up and down the demand for telecom operators, weak markets and threats to their gainful switching.

Christina Aguilera, Keith Urban perform at Cisco's 40,000-person employee party at Levi's Stadium:
Cisco Systems knows how to throw a party. The
giant Levi Stadium Monday night San Jose technology packed with 40,000
people for the feast of an employee - called Cisco Rocks - to celebrate
the outgoing CEO, John Chambers, and his next chapter under the new CEO
Chuck Robbins. And did I mention that Christina Aguilera and Keith Urban gave entertainment?
A video tribute was shown Chambers where his leadership was greeted by a crowd of powerful people, including Bill Clinton, Hillary Clinton, Shimon Peres, Colin Powell, Henry Kissinger and former GE CEO Jack Welch. But this is Silicon Valley, where it is equally important to be able to drill a little fun at yourself when you are on top, so Chambers and Robbins participated in another video - and he, who were dressed in combinations of theft and spoofing "Top Gun".
Both incoming and outgoing leaders addressed the crowd at a Silicon Valley standard equipment of sports shirt and jeans, but the shoe of choice was Cisco Rocks Converse Chuck Taylor All-Stars. Shraddha credit Chaplot Cisco engineer has had the bright idea to invite all employees to use "chucks Chuck" in honor of the new CEO on Monday.
I guess it's a good thing that the first name is Robbins mullet.
TOP GALA GAL: The Four Freshmen were the headliners of Jazz on Tuesday night Plazz Gala in Los Gatos, but the real star was Andrea Skov, who armed the party for about 200 people in La Estancia, beautiful house Larry Arzie and David Stonesifer.
Although he spent a career in marketing and event management for thousands of people, Skov said volunteers make events like fundraising for the music of Los Gatos and art is something completely different.
"This is a matter of making more music and art for children in the community, so that it becomes easier and easier to do it every year," Skov, who was presented with an award for his work in Los Gatos said music and art founders hope Teri and Jonathan Knowles and Jazz in the Plazz executive producer Michael Jacobi.
EYE ON THE BAY OF ART: Art Association of Los Gatos presents an exhibition of the fine arts, the open area of Grand Bay in Numu, the New Museum of Los Gatos August. The exhibition was juried by artist Peggi Kroll-Roberts of Angels Camp and has 66 rooms, which come from the region of Walnut Creek in Pebble Beach.
