It has been a rocky year for Wall Street, but even amid the uncertain market conditions there are some companies that are playing with a lot of cash. In addition, they know how to wisely use their funds, which makes them strong enough to beat any challenge.

One important factor that determines the stability of a company is its corporate cash flow. CNNMoney is looking at stocks with both healthy cash flow and a surplus of cash, which helps them avoid tough situations where they may need to raise their capital (check out its slideshow of these five picks). Another element that CNNMoney takes into account when picking companies is their ability to reinvest cash in ways that assure them a nice profitability.

Let's look at some of the companies that CNNMoney likes:

Over the past year, we have been hearing a lot of bad news about investment banks and insurers. The slumping housing market, credit crunch and subprime mortgage troubles have been leading the headlines, so many of you are probably shying away from financial stocks as almost all the banks have been getting only bad publicity lately.

In the light of those worries about safe investments, CNNMoney is asking us to reconsider our opinions, claiming that there really are some quality stocks in these challenging financial times.

Berkshire Hathaway tops the list, mainly because of its CEO Warren Buffett, who has the experience of surviving previous recessions. While some investors may have impression that the company has a lot of tough times ahead, CNNMoney sees Berkshire with a lot of capital, which could be enough to steer it through the current economic storm. To support this argument, CNNMoney cites Keppler Asset management CIO Michael Keppler, who is convinced that Berkshire will be able to beat the difficult market.

Over the past few months I have written a lot about the housing market, and almost all of what I have written has been negative, so when i ran across an article today discussing some markets where prices are thriving I felt it only fair to discuss.

According to a report from CNNMoney.com there are 11 metro areas that have enjoyed double digit growth in home values over the past twelve months. Just goes to show that the old saying is still true... when it comes to real estate, its all about location, location, location.

So why exactly are there some parts of the country where prices are still going through massive increases while other sections of the nation have seen dramatic drops in prices? There are a couple factors at play according to the report:

1. Strong job market
2. Solid population growth
3. Areas that never went through the massive boom earlier in the decade that sent prices sky high in most of the nation

Late Friday, Dow Jones & Co (NYSE: DJ) said that Financial Times publisher Pearson Plc (NYSE: PSO) has been trying to find partners to pursue an acquisition of Dow Jones, people familiar with the matter said. Shares of Dow Jones & Co. jumped 3% on the news.

It's amazing what can happen over a weekend.

Today's Wall Street Journal, owned, of course, by Dow Jones, reported that General Electric (NYSE: GE) and Pearson are talking about a joint-bid for Dow Jones that would allow the Dow Jones's controlling Bancroft family to maintain a minority interest. The joint-bid would combine GE's CNBC, the Financial Times and Dow Jones into a privately-held joint venture, owned in three equal parts by the three companies. The potential new company would also control Barron's, half the Economist magazine, MarketWatch.com and interests in various business newspapers around the worldwide

Sound like a business news monopoly? Hum.

Another name recently floated as a potential suitors for Dow Jones was billionaire Ron Burkle, who has teamed with the union representing the employees of Dow Jones, and Philadelphia newspaper executive Brian Tierney. Warren Buffet last month said it was "very, very unlikely" that his Berkshire Hathaway (NYSE: BRK.A) would bid for Dow Jones, citing the $5B bid from Rupert Murdoch's News Corp (NYSE: NWS).

Wait. Does that mean that the Oracle of Omaha considers News Corp's $5 billion bid too much? Jonathan Berr of BloggingStocks believes that Murdoch wants the Journal so badly that he's willing to pay an "outrageously high price." Peter Cohan, also of BloggingStocks, thinks the GE/Pearson bid could prevail.

Regardless of Mr. Buffet's opinion, the "lamest bidding war ever," as coined by CNNMoney's Paul R. La Monica, has just started to heat up.

Announcements about major websites moving into video now come fast and furious. You can almost watch the morning news each day to find new video deals on the web.

Today AOL announced that it has entered into a deal with NBC to stream video of two shows, according to CNN Money.

The shows AOL will begin with are Studio 60 On Sunset Strip and Twenty Good Years.

Television and films are now moving to the web in earnest. The interest in the new Amazon film and TV service over IP is only the latest example of tremendous media coverage following each old-media/new-media tie up. At this point video services are now a part of AOL, Yahoo!, Google, and MSN. Slightly smaller sites like CNN and MSNBC have also adopted the model. Rumors of a news video service from Apple may be confirmed this week.

The issue for these service is not whether they will pick up customers. They will, but the numbers are still in question. But not every provider can be a winner. The large sites like AOL have an edge. They already have huge audiences to direct to video portions of their sites. But, if two or three dozen large web properties hit the door at about the same time, it is going to get crowded.

Michael Eisner, former CEO of Disney, wants to once-again be a media mogul.  His resume is amazing, of course – having developed television shows (Happy Days, Welcome Back Kotter, Barney Miller) and movies (Raiders of the Lost Ark, Saturday Night Fever, The Little Mermaid, Good Will Hunting).  He also orchestrated the turnaround of Disney during the mid 1980s.

This time, Eisner sees the next phase in media being online video. To this end, he's on the board of directors of the video-sharing site, Veoh, as well as an investor. The company recently snagged $12.5 million from investors, such as Time-Warner and Spark Capital.

But it's not without its challenges. For example, the adult entertainment company, Io Group, recently filed a copyright infringement suit again Veoh.

Yahoo! closed today at $30.82, lurching down 70 cents. Again, this is somewhat surprising considering that Yahoo! still has some strong recommendations out there going for it. CNN Money today discussed Yahoo! as one of their sexy summer picks, noting that as advertising continues to heat up there is plenty of the advertising pie for both Yahoo! and Google.

But Yahoo! wasn't the only one to tumble today in the technology sector thanks to comments by Fed Chairman Ben Bernanke (oh my, I almost typed in Greenspan by sheer reflex!) and his strong stance against inflation, a statement that hints at possible interest rate adjustments. That little gem had everyone a bit jittery...
