If you're feeling good about the market, you're not alone. Take my hand as we go over some of this week's more uplifting headlines.

1. The sun comes out for Annie
The IPO market is hopping again, and you can thank Bernie the rabbit. Annie's (Nasdaq: BNNY) -- the organic foodstuffs maker that takes its ticker symbol and "rabbit of approval" mascot from the founder's now-deceased bunny, Bernie -- turned in the market's biggest opening-day pop in 10 months.

Annie's was originally hoping to price its deal between $14 and $16. The offering eventually hit the market at $19 on Wednesday morning, but that still wasn't enough. The stock opened at $31.11, closing at $35.92. If an opening-day pop of 89% should lead to a sell-off the next day, there was no buyer's remorse on Thursday. The stock added another 6% gain yesterday.

Annie's sells organic macaroni and cheese, snacks, condiments, and a popular rising-crust pizza.

Rising-crust pizza? I guess Annie's knew how to make dough rise long before this week's debut.

2. Mobile musings
How long did Annie's 10-month record stand? Would you believe that the organic food maker's 90% first-day surge was bested a trading day later?

Millennial Media (NYSE: MM) -- the country's second largest player in display advertising when it comes to mobile -- hit the market at $13 yesterday. It closed 92% higher at $25.

Millennial is the company serving up ads on most of the popular app games. It delivered 45 billion impressions last month alone! It may be too early to tell how lucrative or effective graphical ads on mobile phones may be, but it's clearly a booming market.

3. Howard Stern's wearing legal briefs
Sirius XM Radio (Nasdaq: SIRI) is back in an antitrust legal battle -- but this time it's the accuser.

The satellite radio giant is filing a complaint against SoundExchange and American Association of Independent Music, accusing the organizations of getting in the way of Sirius XM's ability to negotiate royalty rates directly with the individual record labels it represents.

Beyond legal fees, there is little for Sirius XM to lose here, even though anything it recovers will more likely go toward lowering the music royalty fee that it passes on to subscribers than toward material savings on its own bottom line.

Then again, if the customer is happy, Sirius XM should be happy.

4. Tesla gets charged up
Tesla Motors (Nasdaq: TSLA) moved higher after a Wunderlich Securities analyst raised his price target on the electric car maker.

Theodore O'Neill -- upgrading the stock from hold to buy -- also jacked up its price target from $30 to $49 after touring Tesla's facilities. O'Neill believes Tesla can dramatically ramp up its production to 5,000 cars per quarter.

There's already heavy demand for the Model S sedan that hits the market this summer.

5. Tanker tailor soldier spy
Shares of Frontline (NYSE: FRO) also moved higher on a welcome analyst upgrade.

Dahlman Rose is upgrading the oil-tanker operator -- from hold to buy -- and establishing a $9.50 price target that is comfortably ahead of where Frontline is presently perched.

A streak of money-losing quarters as Frontline deals with brutally low shipping rates has pounded the stock that was trading in the mid-$20s just a year ago. Even if most Wall Street pros don't see Frontline returning to profitability until 2014 at the earlier, it's refreshing to see sentiment starting to turn.
