I guess you could say that shareholders of Harley-Davidson (HOG) aren't in hog heaven. The motorcycle magnate announced solid third-quarter earnings results, but it disappointed the Street with its motorcycle sales.

Let's start with the good news. Harley-Davidson reported third-quarter net income of 38 cents per share ($88.8 million) or 40 cents per continuing share, far better than last year's same-quarter earnings of 11 cents per share. What's more, these results topped the consensus estimate of 35 cents per share. The company was even able to overcome poor quarterly sales because of it financial services division and cost-cutting efforts.

The earnings crunch is back on this week. Third quarter reports are due from tech, financial and pharmaceutical companies, from airlines and from many others. Here's a day-by-day rundown of the coming week's earnings highlights, with a closer look at Apple (AAPL), Harley-Davidson (HOG), Boeing (BA) and Southwest Airlines (LUV).

Getting things started on Monday, analysts surveyed by Thomson Reuters expect Citigroup (C), Halliburton (HAL) and IBM (IBM) to post year-over-year earnings growth. But Monday's highlight no doubt will be Apple's (AAPL) quarterly results.

You had to love the excitement surrounding Harley-Davidson (HOG) Tuesday. I'm sure shareholders were jumping for joy at the incredible rise experienced by the stock: it closed on Tuesday at a price of $26.83, up well over 13%. Volume supported the conviction of the move.

Back in April, BloggingStocks' Tom Taulli covered the company's first-quarter numbers. He called the stock risky at the time. He was correct to do so because the shares retreated not long after his piece was published, as the following chart clearly shows. Now that the second-quarter stats are here, should investors be interested in the motorcycle maker?

• Scotia Capital upgraded Apple (AAPL) to outperform from sector perform, citing valuation, potential increased iPhone distribution and iPad upside. The firm's two-year price target is $325.
• UBS upgraded Parker-Hannifin (PH) to neutral from sell following the company's better-than-expected Q3 report.
• Piper Jaffray upgraded Arkansas Best (ABFS) to neutral from underweight after the Teamsters union announced a tentative agreement with the company. The firm has a $33 price target for shares.

Harley-Davidson (HOG) closed yesterday much higher than where it opened. The stock rose over 10%, finally settling at $31.37. During the intraday session, the shares hit a new 52-week high of $31.66. According to TheFly, RBC Capital increased its price target for the motorcycle company, believing it may eventually hit $36.

You know what? My gut tells me $36 is easy at this point (however, I do have some reservations and warnings, which I'll get to). There was a lot of volume backing the bid on Monday, and as I look through different time periods for the stock in terms of price gain (one-month return, three-month return, etc.), I come to the conclusion that this is one strong equity.

Harley-Davidson (HOG) shot up recently on takeover rumors, but in my opinion, they're just that -- rumors.

Who needs a high-end motorcycle during the Great Recession? Or its aftermath? And who needs the stock of a company with more than $4 billion in long-term debt, huge unpaid pension obligations, lousy cash flow to service its debt, and that is still in search of a partner to take customer loans off its hands.

Spring is finally here, which means it's time to break out the broom and dustpan for some spring cleaning.

But your home isn't the only thing that requires constant maintenance -- your portfolio does too.

And what better time than spring to get a fresh start by cleaning out the stocks that are sitting around collecting dust rather than making you money?

This is a cornerstone of the Fed, a true shibboleth (Google that one). But one of the first set of bonds the Fed bought under the TALF program were bonds backed by motorcycle loans made by Harley-Davidson (HOG) to its customers.

The Fed program was designed to provide loans and capital to businesses that were shut out of frozen credit markets, which is a good thing. But loans to Harley made to boost the sale of motorcycles to people who could not get loans elsewhere?
