I had previously thought about buying shares of $ABNB, but ended up not buying them. However, I find $BKNG quite interesting as it has very good numbers and has been growing strongly recently. The stock is overvalued right now though, so we'll see if maybe there's a correction after this week's results.
I see it as a very cyclical sector, so I don't invest in it.
$BKNG has better performance here, but the stock is quite expensive right now. After a 15% drop, though, I'd be starting to think about buying.
