"The stock market is a no-called-strike game. You don't have to swing at everything -- you can wait for your pitch."

Warren Buffett's words are as true now as ever. The obvious message is to wait, patiently, for your pitch. The implied second message, which Buffett has perfected, is that when your pitch does come, you need to swing. Hard.

The first pitch we swung at for the Young Gun Portfolio was Pebblebrook Hotel Trust (NYSE: PEB). This opportunistic hotel play remains my highest-conviction idea, and with its recent dip in price, it's time to book another room.

As I outlined in my initial buy recommendation, Pebblebrook is an investment vehicle formed solely to take advantage of cheap hotels going on sale in the wake of the real estate crash. Nothing about my thesis has changed since.

Great deal prices
CEO Jon Bortz and his team continue to see the fire-sale hotel prices that prompted him to come out of retirement and form Pebblebrook in the first place. The company's latest deal, for the Argonaut Hotel near Fisherman's Wharf in San Francisco, closed at a 25% discount to replacement cost. Furthermore, Bortz said recently that he refuses to chase hotels if competing bidders drive up their prices. I like that discipline -- and it should continue net us superior deals.

Strict style discipline
An analyst on the last conference call asked Bortz whether he would consider looking for hotels in suburban locations, outside his tried-and-true specialty of upscale, urban properties. Bortz's answer was a resounding no; he's sticking to the niche that made his name over the past 17 years. Buffett would be proud of Bortz's ability to stay in his circle of competence.

Opportunistic to the bone
Bortz's penchant for picking up hotels cheaply is impressive, but his dexterity in capitalizing on unique situations is even more remarkable. His first hotel purchase was the Bethesda Doubletree. Located in Bethesda, Maryland, the Doubletree is the closest hotel to both the National Institute of Health and the National Naval Medical Center, which are undergoing a joint $1 billion expansion. When completed later this year, it's expected to double both facilities' number of visitors. Shouldn't be hard to keep the Doubletree's rooms filled after that.

Bortz's opportunistic streak showed up again in two recent purchases. The Sofitel Philadelphia is located close by the Philadelphia Convention Center, a 60% expansion of which is scheduled to be finished in the second half of this year. And the Argonaut Hotel -- besides being designated a national historic landmark -- is set to benefit from the America's Cup, which will be hosted in San Francisco and headquartered just a few blocks from the hotel.

OK, maybe ONE thing has changed
If anything, Bortz and his team's resolve in sticking to their guns has strengthened my confidence in the company. On top of that, the latest annual report and conference call have given us more insight into Pebblebrook's financial workings. Though its 2010 results are still somewhat opaque, since we have yet to year-cycle any hotel purchases, they have still exceeded my expectations. The deals closed since I built my initial model are even better than the previous ones, and with $350 million or so of buying capacity left, the company has plenty of dry powder to take advantage of further deals as they arise. My model reaffirms that shares could be worth $30 or more.

When you get a pitch you like, you need to swing. My confidence in Pebblebrook has never been higher, so I'm doubling our position from 3.5% to 7%. To stay current with all my swings -- as well as the pitches I let pass -- follow me on Twitter.
