Airbnb’s strong performance in the fourth quarter is tied to the recovery of traveling. From Visa and Mastercard’s reports, cross-border payments have increased significantly, but both giants mentioned that retaliatory tourism has begun to slow down in the short term. This would also be a short-term risk affecting Airbnb. However, from a long-term perspective, Airbnb's moat is getting stronger and stronger, because it’s difficult for Airbnb’s peers to accumulate 660万 listings, and Airbnb’s geographical flexibility is unmatched by any hotel brand. The company is also planning to develop the apartment listing market, which will undoubtedly provide a greater growth potential. In addition, after the company has gone through the epidemic, it has already gained a lot of operating leverage, so Airbnb should be a good investment in the long run. However, if a recession did come, pro-cyclical stock like Airbnb can be affected greatly, which can be a short-term risk.
