After-hours traders punished Dell (DELL) stock Thursday, following a weak third quarter earnings report from the technology giant.

Going into the afternoon earnings release, analysts had been expecting to see the company show earnings of 28 cents per share. Actual earnings came in much lower at 23 cents per share.

Analyst upgrades:

• Goldman upgraded Aeropostale (ARO) to neutral from sell. The firm, which has a $34 target on the stock, cites the recent sell-off in shares for the upgrade.
• Janney Montgomery upgraded Consolidated Water (CWCO) to buy from neutral on valuation and on expectations the company's earnings will recover in 2010. The firm has a $15 target on the stock.
• Wunderlich upgraded Transmontaigne Partners (TLP) to buy from hold on valuation as it believes the sell-off on the company's Q3 results is overdone. The firm keeps a $26.50 price target on the stock.
• Mobile TeleSystems (MBT) was upgraded to buy from neutral at UBS.
• HSBC (HBC) was raised to buy from hold at Societe Generale.
• Redwood Trust (RWT) was upgraded to outperform from market perform at JMP Securities.

Did you a get chance to establish a position in Hewlett-Packard (HPQ) back in April? If you did, you're up a nice 39%. But the equally comforting news is that there's still considerable upside ahead for HPQ, which is why I'm reiterating my buy rating for the company, first recommended on April 24, 2009 at a price of $35.80.

Hewlett is well-positioned to increase market share in PCs, servers, printers and IT services. The company's cost reduction efforts have gone reasonably well, and it's made progress re-positioning its customer services operation to become the one-stop shop that many customers seek. Meanwhile, the integration of Electronic Data Services, acquired for about $13 billion, should go reasonably well.

The latest litigation has Intel Inside.

The State of New York is going after Intel (NASDAQ: INTC) over antitrust allegations. State Attorney General Andrew Cuomo is accusing the largest chip manufacturer in the world that it is trying to secure a global monopoly for microprocessors.

For several years, Cuomo said that Intel has pushed the likes of Dell (NYSE: DELL) and Hewlett-Packard (NYSE: HPQ) to agree to the exclusive use of Intel's gear in exchange for billions of dollars in payments. The hefty cash outlays have given what Cuomo called a "stranglehold" on the market.

Neither company is saying a thing yet, but word is Cisco Systems (NASDAQ: CSCO) and EMC (NYSE: EMC) are joining up to sell a new collection of products designed to deliver cloud computing capabilities, Reuters reports. Called vBlock, the cloud solution is intended to help the companies compete more effectively with IBM (NYSE: IBM) and Hewlett-Packard (NYSE: HPQ).

The partnership, which no one is admitting to, involves a joint venture between Cisco and EMC that will sell vBlock. The former will supply the networking equipment and servers, with the latter kicking in the storage gear and virtualization technology through its VMWare (NYSE: VMW) subsidiary. The joint venture will put the systems together, integrate the components for clients, and make the whole pile of cables and silicon work. A formal announcement is expected next week.

Windows 7, the latest operating system from Microsoft (NASDAQ: MSFT), is expected to help jumpstart some IT spending. Intel (NASDAQ: INTC) also sees this happening. A new operating system often means a chance to upgrade from dated equipment that isn't worth upgrading, especially with favorable pricing for technology right now. Everything's coming together for a strong 2010 for the high-tech sector, so it's also worth watching Hewlett Packard (NYSE: HPQ), Dell (NASDAQ: DELL) and EMC (NYSE: EMC).

International Business Machines (NYSE: IBM) reported Q3 results after the bell on Thursday. Net sales decreased 7% when compared to the year-ago period. Okay, that doesn't sound like a great start. Wait, though, because things are about to get better from here.

Sales actually increased 1% on a sequential basis. Net profit on a dollar basis went up 14%. Net margin improved. And on a per-share basis, net income jumped 18% to $2.40. According to our earnings preview, this was two pennies ahead of analyst projections.

Economic recovery starts on the ground. So, while it's nice to hear the likes of Stephen Schwarzman celebrate the return of IPOs and hefty exit strategies, the real indications that the economy is turning the corner will come when companies start to open their wallets and spend.

After dealing with only the have-to-haves for a while now, companies can start to make the improvements they've been putting off. Dell (NASDAQ: DELL) CEO Michael Dell sees this happening in the IT space, with companies expected to ramp up their hardware spending aggressively.

Microsoft's (NASDAQ: MSFT) new operating system, Windows 7, is set to be released on October 22, 2009, but it's unlikely to have an impact on PC prices. So, if you're feeling the urge to rush out and buy a new box, try to hold out until the end of the month. You'll get a bit more life out of it.

Fortunately, PC prices aren't expected to get much lower, so the entire supply chain -- from chips to software -- has nowhere to go but up. The effect, though, has been to put some serious pressure on manufacturers and retailers to keep from screwing up the release.

Salesforce.com (NYSE: CRM) has a new champion: Dell (NASDAQ: DELL). The PC manufacturer is promoting the online sales force-enablement platform as a way to gain access to the hefty sums available in the technology services business. The deal would give Salesforce.com access to Dell's clients in the small and medium-sized business categories. Dell would sell Salesforce.com products and provide consulting services to help clients integrate the solution with their other enterprise applications. The dollars and cents of this union weren't disclosed.

Dell sees the margins of the services business and wants a piece of the action, particularly since the PC sector is low margin. Also, sales have been hit pretty hard as a result of the financial crisis. With PCs accounting for 60% of Dell's top-line, a bit of diversity isn't a bad idea. Currently, services account for only around 10% of Dell's sales.

"At 12 times trailing earnings, Hewlett-Packard (NYSE: HPQ) trades at a 21% discount to its three-year average valuation and looks cheaper than other U.S. computer giants," says blue chip advisor Richard Moroney.

In Dow Theory Forecast -- a newsletter that has been published for over 5 decades -- he looks at the firm's diversified position and the reasons behind his "long-term buy" rating on the shares.

"For a company that chose its name via a coin toss, Hewlett-Packard takes a deliberate approach to dealing with trouble; its founders designed their first factory so it could be turned into a grocery store if the technology business failed to grow.
