Airbnb (ABNB -2.37%) stock has deeply enriched investors' pockets over the past year, with a return of 120% since its December IPO. However, shares have fallen 30% from the all-time highs in February due to concerns regarding the emergence of dangerous coronavirus variants hindering global travel.

The temporary setback gives investors a rare opportunity to gain access to an otherwise high-flying tech/travel company at a fair price. Here's why you can put all your eggs in one basket when it comes to Airbnb stock.

What's with the appeal? 

Since its inception in 2007, Airbnb has welcomed over 900 million guest stays in almost every country across the world. The company's value proposition is pretty huge as it allows travelers to stay in a home far away from home with full amenities (Wifi, fully stocked kitchen, pet friendly, etc.). Guests get more comfort than traditional brick-and-mortar hotels can offer and at a fraction of their cost.

But the genius part is that Airbnb introduces a symbiotic relationship with the existing hotel/vacation rental industry instead of simply disrupting it. Hotel, resort, campground, or bed and breakfast managers can list their properties directly on Airbnb to cater to a vast audience on its platform. The business model is highly scalable, as Airbnb merely takes a commission fee from guests' bookings.  

Is the stock overvalued? 

Right now, Airbnb stock is trading at roughly 17 times price-to-sales. That's pretty expensive for a company that only grew its revenue by 5% year over year to $882 million in first-quarter 2021. Simultaneously, its operating income less non-cash expenses (EBITDA) is still in the red at negative $59 million. That number did, however, improve by $275 million over Q1 2020.

Luckily, Airbnb's management is anticipating a massive revenue rebound as vaccination campaigns gain momentum worldwide. Its platform's gross booking value is already exceeding $10 billion per quarter from properties run by over 4 million hosts in 100,000 cities worldwide -- and growing. On a side note, that number is up 52% year over year due to increased long-term rentals. 

About 150 million people booked a property via Airbnb last year. It already accounts for over 20% of vacation rental markets in countries like the U.S. This makes the company well-positioned to ride the rebound in global travel. The company lost nearly 54% of its expected revenue due to the coronavirus, so there's definitely colossal growth potential up ahead. 

But perhaps the biggest benefit the pandemic had for Airbnb was giving it a straight path to profitability. Recently, company management discovered that they could slash marketing expenses to a very low level -- and rely only on the strength of its brand to generate revenue.

Indeed, about 90% of traffic on its platform did not originate from advertisements. That's a pretty major discovery as the company currently spends about $228 million per quarter (or 25.7% of sales) on marketing. I believe that Airbnb could easily attain its goal of achieving 30% EBITDA margins (instead of negative 6.7% at the moment) in the near future by cutting costs in this segment.

Time to go all-in? 

Airbnb is also doing a great job capital management-wise with nearly $6.4 billion in cash and investments to offset just $1.8 billion in long-term debt. Overall, due to a strong brand moat, high scalability, and a clean balance sheet, Airbnb stock is a safe bet to move all-in. The company's growth is on the verge of a breakout due to a travel backlog and could witness upwards of 60% to 80% year-over-year increase -- which is more than enough to justify its valuation multiples. Therefore, it is a high-flying tech stock you don't want to miss.
