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. K-Cup marks the spot
It was a good week for Keurig Green Mountain (GMCR.DL), which kicked off the week by announcing a deal with BJ's Wholesale Club to offer the warehouse club's private-label Wellsley Farms coffee in K-Cup packs for Keurig's single-serve platform.

It's a pretty big deal because no one has to work directly with Keurig Green Mountain to put out K-Cups, as key patents expired two years ago. However, Keurig Green Mountain has suggested that it offers production consistency, preferred distribution, and the ability to offer portion packs for all of Keurig's newer platforms.

Later in the week, it was Dougherty & Company putting out a report claiming that Keurig Green Mountain K-Cup unit sales for the four weeks through mid-June had accelerated to 11.5%. In other words, even before the BJ's deal, we saw an uptick in official K-Cup unit volume. 

2. Pop goes the barista
Starbucks (SBUX 1.09%) is trying to do for soda what it did for coffee. It began offering handcrafted sodas -- more specifically, ginger ale, spiced root beer, and lemon ale -- at roughly 3,000 stores across the Sun Belt this week. 

Starbucks has been testing the pop push since last year, but now it's making the big push just as the peak soda-drinking season gets underway. Starbucks' Fizzio line of carbonated beverages claims to be superior because all of the ingredients are combined before the carbonation takes place. We'll have to see what consumers think about that this summer, but at the very least, Starbucks has a new product line to push this season. 

3. Sonic revs its engine
Sonic (SONC) keeps schooling the larger burger joints. The chain of 3,500 "drive-in" restaurants posted another better-than-expected quarter on Monday. Comps clocked in 5.3% higher. Compare that to Mickey D's, which is likely wrapping up its fourth consecutive quarter of negative comps.

Sonic didn't have to give away the store to drum up that growth. Operating profit and net income rose 6% and 13%, respectively. Now all Sonic needs is to start expanding at a healthy clip again to cash in on its revival. 

4. Sirius staying power
Sirius XM Radio (SIRI -1.29%) continues to make inroads with automakers beyond its flagship satellite radio offering. In two different deals, Sirius XM announced that 2015 Lincoln and Chrysler model cars rolling out later this year with SiriusXM Traffic and SiriusXM Travel Link will come with multiyear subscriptions. 

Tethering drivers to five years of service with Chrysler and six years for Lincoln lock them up for the long haul with its platform. Sirius XM is also incorporating new features that will do everything from displaying fuel prices at nearby gas stations to offering up movie listings. 

5. GoPro and go home
The IPO market got a welcome boost with GoPro's (GPRO -0.57%) well-received debut. The leader of wearable cameras hit the market priced at $24 on Thursday morning, but it opened at $28.65 and wound up soaring 31% on its first day of trading. 

GoPro was a hit despite posting a surprising decline in revenue in its most recent quarter after seeing sales soar 87% last year.
