"For investors with a more aggressive bent, one stock on our radar is Nuance Communications (NASDAQ: NUAN)," says trading and investing expert Bill Martin.

In BullMarket.com, he explains, "The firm's core niche is producing speech-based voice-recognition and synthesis software for use in corporate customer-care operations, mobile applications including the new iPhone and to automate health records."

"Nuance creates those automated voices you have to listen to when what you really need is a human being to tell you why your cable modem isn't delivering the Internet.

Alas, I had to say good-bye to an old friend Nuance Communications (NASDAQ: NUAN). This is a technology company that specializes in speech-recognition software and digital-document solutions, and it competes with the likes of IBM (NYSE: IBM) and Microsoft (NASDAQ: MSFT). It's a cool business, although it grows by acquisition, so you do have to watch that part a bit (i.e., checking the GAAP vs. the non-GAAP numbers, cash flows, etc.). The 52-week high on the stock is $22.55; the 52-week low is $9.31. I remember thinking when the stock hit the high that maybe it was time to sell out. I wish I had. But I had confidence in its long-term future. I still do.

As we all know, though, everything has changed. The financial crisis is bringing everything down to irrational price levels. Shorting is one of the only ways to make money. And capital preservation is now on the top of everyone's agenda. That's what my sale of Nuance was about. It's one of the few stocks I owned that still showed a profit. I bought in well below $10 per share. I sold my shares on Friday for $10.13. I can always buy them back when things settle down. I should have sold a lot earlier during the downtrend; I could have generated more proceeds.

And that's one of the reasons why I'm writing this post. I want to tell you why I didn't try to raise some cash by selling Nuance at a better time period. I want to help you not be the idiot that I was. Okay, ready? Here goes. I didn't sell earlier because I held Nuance in a taxable account and didn't want to deal with paying the capital-gains taxes in '09. Like they say, if you get too cute about avoiding taxes, don't worry, you won't owe them because you'll have no profit. And that's a great way to get rich, of course (big sarcasm there, in case you didn't notice).

United (NASDAQ:UAUA) is up 3% on news that it cut staff and capacity.

Ambac (NYSE:ABK) is up 2% after a huge sell-off yesterday on word it may be downgraded by Moody's

Stocks may trade differently in the pre-market than they do the regular session.

Nuance Communications (NASDAQ: NUAN), a business devoted to speech recognition technologies and document solutions, reported Q2 earnings earlier this week. Those of you who own this stock know that the company oftentimes puts forth a complicated earnings release, full of GAAP and non-GAAP stats. This is due, in part, to the company's acquisition strategy (not long ago, I wrote about Nuance's purchase of eScription). So, on a GAAP basis, don't expect much. Net loss per diluted share expanded to $0.13 versus a net loss per diluted share of $0.01 in last year's second fiscal quarter (there was a significant non-cash-stock-based compensation charge included in the current quarter). Top-line revenue did well on a GAAP basis, however, rising 54%. Again, though, this growth was due to acquisitions.

On a non-GAAP basis, things look much brighter. Revenues rose 63%, and net income per diluted share increased 50% to $0.18. According to Reuters, this figure matched analyst expectations (I would have liked to have seen Nuance beat expectations, but it is what it is). Of course, Nuance stimulates a classic bull-bear discussion in terms of when GAAP profitability becomes more of an issue than non-GAAP success. As a Nuance shareholder, I definitely would like to see GAAP profits on a consistent basis, but I am well aware that management intends to gamble on acquisitions as a method for creating shareholder value, and for now, I am willing to be patient and watch how the company proceeds.

Nuance could be considered a risky, speculative stock in many ways, but I think it has a good chance of doing well over time with its technologies. You'd probably sleep better with competitors Microsoft (NASDAQ: MSFT) and IBM (NYSE: IBM) in your portfolio, but since I own it from around $9 per share, I'm willing to wait and see how the share price moves from this point forward (admittedly, I was considering booking profits recently, but decided against such action). Anyone thinking of getting in now might want to perform a lot of due diligence and wait for the proverbial pullback.

Disclosure: I own shares in Nuance Communications; positions can change at any time.

It's not a terribly exciting day today in terms of the market averages, but there are some stocks doing well. Nuance Communications (NASDAQ: NUAN) is one of them.

Nuance, which provides technologies for speech recognition and solutions for document needs, is up 5% on better-than-average volume as I write this. The catalyst? It appears to be a deal -- what else is new? Nuance is definitely an asset collector, and its business model is based, in part, on leveraging its various acquisitions to drive long-term shareholder value. It needs to do this as effectively as possible to compete with big guns such as Microsoft (NASDAQ: MSFT) and IBM (NYSE: IBM). That can be risky, but so far, the stock has done well for me -- I've owned this for a while, and my cost basis is somewhere around $9 per share. Lately, though, I've been thinking of selling, as the stock still has yet to break through its 52-week high of $22.55 (shares are currently trading around $18.60) -- I thought that event would have happened a while ago, but I was wrong.

The acquisition announced today was for eScription, a business involved in transcription services for the medical industry. Sounds good to me -- anything to do with helping health care become more efficient should be valuable over time. The price tag was pegged at $400 million. I'll be watching the price action on Nuance -- hopefully it'll make a fresh run toward that 52-week high soon.

Disclosure: I own shares in Nuance Communications; positions can change at any time.

Last week, V-ENABLE got a big score. The company announced a deal with MetroPCS Communications (NYSE: PCS) to provide a mobile 411 service, which is based on a monthly payment. Keep in mind that the typical wireless operator may charge as much as $2 per 411 call.

To get some more perspective on things -- and the 411 sector -- I had a chance to interview Dipanshu Sharma, who is the founder of V-ENABLE.

Q: How are things at V-Enable? What are you seeing in the free 411 marketplace?

A: V-Enable is doing quite well. Life at V-Enable is busier than ever. V-Enable is in the center of a business that is in transition. 411 is an age-old business and had not seen much innovation for decades. With the advent of local advertising shifting from yellow book to internet and now to mobile, the 411 business is seeing its share of innovation. There are three business models that are currently being practiced

1. Regular $1.50-$1.79 per 411 call (declining)

2. Unlimited 411 calling for a fixed price $2.99-$3.99

3. Free Directory Assistance (advertising supported)

Both unlimited and FREE DA models are seeing fast growth. The unlimited model allows users to talk to the operator without any annoying voice advertising and also limiting how much users spend on 411 per month. Free models takes all the cost away but users have to deal with voice ads.
