Netflix (NFLX) stock is soaring this morning, up 36% ($37) to $140 per share in pre-market trading. The company's fourth quarter financial results were above expectations, but at first glance do not appear to warrant a 36% stock price increase. Revenue rose 7.9% year-over-year, leading to a very small quarterly profit of 13 cents per share.

Investors are enthusiastic about Netflix's addition of 2.05 million domestic streaming customers (up 8.2% versus the prior quarter), but that figure is a bit misleading as actual paid customers rose by just 1.67 million (+7.0%). Obviously, lots of free trial memberships are given out at the holidays, but how many of them convert to paying customers is a big question mark.

It was also a good sign to see operating earnings from the domestic streaming segment rise to $109 million in Q4, versus just $52 million a year ago. The DVD mail segment earned $128 million domestically for the quarter, which just goes to show you how much more profitable those subscribers are. The DVD mail business earned more money, despite having just 8.05 million paid subs, versus 25.5 million paid streaming subs.

Netflix continues to see subscriber losses in its most profitable segment and gains in a streaming business that has very high operating costs. Just how valuable a streaming customer actually is will remain an important issue for investors. Based on the stock's rise this morning, you would think streaming customers mint money for the company. Conversely, Netflix reported segment profits of $4.25 per paid subscriber during the fourth quarter. That comes out to less than $1.50 per month in profit from the $8.00 per month in revenue they generate.

Back in August, with the stock floundering in the mid 50's, I wrote an article on Seeking Alpha entitled "Netflix Is Finally Cheap." I did not buy the stock, which in hindsight was a mistake since the analysis was correct. With the stock around $140 as I write this post, I can not justify an equity valuation of $8.25 billion for the company, so if you have played this stock correctly lately, you might want to strongly consider lightening up on your long position into today's strength.

Investors have been speculating for a couple of years now that Michael Dell could eventually take his computer company private, after leaving the option on the table in multiple press interviews. His large stake as founder and CEO (about 15% of the company) coupled with his transformation plan and lack of respect on Wall Street (for the stock, not himself) all make a leveraged buyout seem logical. With news that a deal is being negotiated and could be finalized shortly in the $13-$14 per share range, I think the deal makes a lot of sense and others might take Dell's lead and follow suit.

All of the ingredients required for a successful LBO are there in Dell's case. The stock is so unloved on Wall Street that even after a premium is attached to the shares (which were hovering around $10 before news of the deal discussions leaked) the company can be had for a very attractive price. The company generates about $4 billion of cash flow annually, with $3.5 billion or so left over after capital expenditures. With a market value of around $23 billion, which excludes $6 billion of net cash on the balance sheet, Dell and his group would be paying about 4 times EBITDA.

Bears on the stock will be quick to point out that Dell still gets the majority of its revenue from desktop and laptop computer sales and that business is in decline thanks to the emergence of powerful smartphones and tablets. Indeed, that is why the stock has been pressured lately and accounts for the meager enterprise value assigned by the public market, but it also ignores the transformation plan that Dell and his team have slowly been implementing. While PC deterioration is offsetting the financial benefits of the company's move into the corporate world of servers, storage, security, and services right now, over time that side of the business (which is both Dell's current focus and future) will overtake the PC side and allow the company to continue to book strong profits. Once PCs dwindle to 20-25% of the business over the next several years, Dell can re-IPO and the LBO investors can cash out big time. At that time, Dell will look more like IBM than HP.

So why might other companies seen as "old tech" go down a similar route as Dell? First, it makes it a lot easier after someone else does it first, as it gives credibility to the idea. Companies heavy into PC-related businesses are not going to get respect from Wall Street going forward. Dell's pre-deal P/E ratio of 6x proves that. After a while, the frustration mounts and staying public loses its luster. Hewlett Packard is likely going through a similar thought process right now, even though they are far behind Dell in orchestrating a solid transitional game plan. Even PC-related software companies like Symantec are being painted with the same brush and could explore the idea of going private. Anti-virus software is simply seen as yesterday's technology and lacking growth potential.

All in all, this Dell LBO idea makes a lot of sense on multiple fronts, and while other companies might not have as many strong cards to play to make a deal like this work, I bet a finalized Dell deal prompts a lot of discussions in board of directors' meetings across the industry in coming months.
