Server/deskstop virtualization software solutions designer Citrix Systems (NASDAQ: CTXS) continues to advance, as expected, which is why I'm Reiterating my Buy rating for the company, first recommended on June 16, 2009 at a price of $33.09.

In June, the argument was made that U.S. information technology spending would not decline by the projected 5-7% in FY2009, and that institutional investors would also look past CTXS's flatish FY2009 revenue to a near 10% gain in FY2010, and that's pretty much what has transpired. Shares have risen about 19% since the June Buy recommendation. The First Call FY2009/FY2010 EPS estimates for CTXS are $1.64 to $1.88.

Has the recent share price surge in virtualization and remote access software developer Citrix Systems (NASDAQ: CTXS) been excessive? Indeed it has, but that does not blot-out the Buy on a pull-back thesis, for moderate-risk investors. Here's why:

In general, analysts see 8-12% revenue growth for Citrix in FY2009, aided by gains in license updates and services, and by firming results in new product and software purchases.

TheStreet.com's Jim Cramer says these stocks have become too expensive without takeovers and a more robust economy.

One after another after another, these software charts are amazing. And, I might add, a bit scary. How did McAfee (NYSE: MFE) (Cramer's Take) make that kind of move just on security software? Didn't Microsoft (NASDAQ: MSFT) (Cramer's Take) just say -- admittedly for the 4 millionth time -- that it was going to give away free anti-virus software? Or Citrix (NASDAQ: CTXS) (Cramer's Take)? What's that all about? How could it return to those levels?

There were rumors of a Cisco (NASDAQ: CSCO) (Cramer's Take) takeover a week or two ago, and, amazingly, when it didn't come true, the stock hung in.

Broadcom (NASDAQ: BRCM) reports tonight and it is getting hit due to the poor report from Qualcomm (NASDAQ: QCOM). QCOM lowered guidance quite a bit -- in fact, enough that I likely may not have to worry much about QCOM for the next couple quarters. Low $30's would present solid value.

Getting back to BRCM, I still feel it is one of the few must own chip names. I think it has enough innovation and diversification to avoid the 35-40% sequential reductions I am seeing from many in the chip space. However, I also think a lowering of the bar is priced into BRCM's shares and anything less than a disaster should keep the stock above $16.50 (assuming we avoid another shock down to the whole market). Anything around that level ($16.50) and lower would have me adding the shares. I've taken gains recently in trading shares and am hoping to add BRCM back on just a bit more weakness.

Through my career I've generally stayed apolitical with regard to investment and trading decisions, but there have been times when some higher percentage trades have presented themselves due to political circumstances. Examples include: the tech push in Clinton's second term, the defense sector after Bush's 2000 victory, as well as the oil patch. Based on that, here are some overriding thoughts, in no particular order.

The market has moved to the phase where many if not most participants want and expect a pullback. Since the market confounds the greatest number of players most of the time, is a big pullback a lower probability event now? Moreover, does the selling panic of much of October turn into a buying panic in the coming weeks and months? I'm letting the charts lead me here but aware that this bullish case could possibly trump terrible economic conditions.

I still think the alt energy patch (solar, wind, battery tech, clean coal) will produce some of the best winners, but a lot of easy money has been made in just days. Quality and fundamentals will likely count much more now than over the past few months. Also, extended runs may become vulnerable quickly if policy decisions do not show quick tangible follow-through. Companies with the best balance sheets and funding sources will benefit the most and have the least downside on sharp technical pullbacks.

A group of tech veterans -- DD Ganguly, Jayant Pandit, Saurav Mohapatra, Sundar Subramanian and Rohit Shankar – have worked on various projects, despite being in far-flung places across the globe. They did so by leveraging free technologies such as Skype to help manage things.

However, they also wanted to share screens, but couldn't find anything for it as the conferencing software was either too expensive or complicated. So, they started a new company: Dimdim.

That was in 2006 and, as of now, Dimdim is getting lots of traction. In fact, the firm has raised $6.4 million in venture capital. The investors include: Index Ventures, Nexus India Capital and Draper Richards.

Dimdim is available as downloadable open source software. There is also an on-demand version.

For the most part, Dimdim is gunning for a large market opportunity. For example, Cisco (NASDAQ: CSCO) purchased WebEx for a whopping $3.2 billion. Other major players in the space include Microsoft (NASDAQ: MSFT), Citrix (NASDAQ: CTXS) and Adobe (NASDAQ: ADBE).

So, if Dimdim can develop an enterprise-ready version and can provide it on a low-cost basis, the impact could be highly disruptive. And now, the company has some capital to give it a try.
