Juniper's (JNPR) shares have risen significantly since the company's previous earnings release unlike Cisco (CSCO), which have trended in the opposite direction. This could imply that investors are more excited about Juniper's upcoming products relative to Cisco's. One of these is its new data center technology previously called Project Stratus, which is now being branded QFabric. Besides Cisco, Juniper also competes with Hewlett-Packard (HPQ), Alcatel-Lucent (ALU) and Huawei-3Com in the network equipment business.

Our price estimate for Juniper's stock stands at $32.59, which is roughly 23% below the current market price.

Juniper Networks (JNPR) plans to unveil its new networking system on Wednesday called QFabric, The Wall Street Journal reports.

The increase in data from mobile devices and 'cloud' applications programs delivered over the Internet are creating demand for more computing and storage systems. Juniper's new network claims to be a better mousetrap. Its system is geared toward large data centers. It connects servers and storage devices more directly than traditional systems.

Juniper Networks (JNPR) is on the upswing, with the stock catching a 6% boost Wednesday morning on the heels of a well-received fourth-quarter earnings report. Juniper reported a quarterly profit of $190.2 million, or 35 cents per share, substantially improved from its year-ago results of $22.9 million, or 4 cents per share. Excluding items, earnings improved to 42 cents from 32 cents per share on a year-over-year basis.

Meanwhile, revenue for the quarter increased 26% to $1.19 billion. Gross margin retreated slightly, falling to 66.6% from 67.1%.

Stocks opened lower after a downbeat report from Cisco Systems on its guidance. The G20 meeting of leaders of the industrial and developing countries in Seoul, South Korea, is beginning discussions on world trade and currencies. The currency markets are roiled again, with the US dollar gaining strength against the Euro, primarily on fears that the European Union will have to do something about Ireland's debt. Something like a bailout similar to the Greek bailout of earlier this year.

Cisco Systems (CSCO - option chain) shares are rising today after company CEO John Chambers said in an interview that tech companies often are among the first to see gains in a recovering economy as businesses upgrade their technology. This could be a good sign for the company, which is scheduled to report Q2 earnings on Wednesday evening. Analysts are looking for the company to post a profit of 35 cents per share on revenue of $9.4 billion, compared to a profit of 32 cents per share on revenue of $9.09 billion in the year-ago period. A good quarter announced last night by competitor Juniper Networks (JNPR) also bodes well for Cisco next week. If you think that the stock won't fall by too much in the coming months, then now could be a good time to look at a bullish hedged trade on CSCO.

TheStreet.com's Jim Cramer says managers are being judged on their exposure to this rally.

Did Abbott Laboratories (NYSE: ABT) (Cramer's Take) scare the shorts? Or was it so easy to get people to buy winners and sell losers at the end of the quarter that the market had to go higher? What makes a thin market levitate rather than decline?

I got to thinking about this and the incredibly bullish comments by one of my favorite strategists, Byron Wien -- comments that are even more bullish than usual for him -- and concluded that the single best thing that the bulls have going for them is that the market is up big and you look like a real knucklehead if you aren't invested or haven't made any money on the long side going into the fourth quarter.

Cisco (NASDAQ: CSCO) reported Q3 stats after the bell on Wednesday. How did the tech company that runs with the likes of Hewlett-Packard (NYSE: HPQ), Juniper Networks (NASDAQ: JNPR), and Alcatel-Lucent (NYSE: ALU) fare? Very well, thank you.

Well, let me clarify that. Cisco saw a lot of declines in its numbers, but we all know what the most important thing to investors is: beating the Wall Street analysts. In this regard, Cisco's management did just fine. As I observed in my earnings preview piece, the call was for Cisco to do somewhere around 25 cents per share. Well, the company bested that figure by an awesome nickel on an adjusted basis.

Tech investors will be looking forward to seeing how Cisco (NASDAQ: CSCO) made out in the third quarter. The networking entity, whose colleagues include Hewlett-Packard (NYSE: HPQ), Juniper Networks (NASDAQ: JNPR), and Alcatel-Lucent (NYSE: ALU), will be reporting Q3 numbers on Wednesday, May 6, after the market closes. According to analysts, Cisco is not expected to grow the bottom line. The call is for 25 cents per share. If that figure is hit, then it will represent a drop of more than 30% on a year-over-year basis.

Here's the bright side, though. Cisco has beat the analysts at their game in recent times. Quite frankly, I think Cisco should be able to come ahead of estimates this week. I don't necessarily see why the trend will break. It's not like the stock has been telling the market that it will. Shares of Cisco have been doing well.

This was one of those days that if you just looked at a large group of stocks you would have no feel for the closing bell levels. The FOMC Minutes from the March 17 to March 18 meeting were given some of the blame for the late day sell-off, although if you have to read one-month old data to get insight into a post-Fed action event explaining it... then something is wrong.

Hence the late-day recovery after that. The reality is that traders are still using any excuse to take a profit or to lighten up after a four-week run, and there are still buyers out there to meet them. Here were today's unofficial closing bell levels:

Dow 7,837.11 +47.55 (0.61%)
S&P 500 825.16 +9.61 (1.18%)
Nasdaq 1,590.66 +29.05 (1.86%)
