Google is "propped up" by index funds*. Everyone who isn't an edgy reddit wsb/crypto meme lord has been told over and over to buy SPY et al with religious devotion and take the "guaranteed 6/7/8/9/10%" annual returns to a happy retirement. They tend not to touch their portfolios until things get super ugly, which we may see soon.
*propped up is a bit complicated here, people are just buying these bundles of corporations without making any value judgement on them individually. More realistically though, Google is the one propping up a bunch of companies that aren't as actively traded but are still on the index. People you've never heard of like Leidos Holdings, or companies that make you deeply question the contents of the index like Bath & Body Works, Inc. and Norwegian Cruise Line Holdings Ltd.
No one holds the sentiment that Coinbase or growth stocks is a risk-free investment. Google on the other hand was held to the esteem of being cash / better cash equivalent. It's not.
I can't read OP's mind, but their earnings call is tomorrow.
Coinbase is a very successful business with actual earnings and a large profit margin, it's just people's opinions of its future income that have changed.
Google went down from $3000 to $2270 in recent months. Affirm is down 27% ... today.
Is this because HN was cynical and hating on Coinbase that it would go no where and then it did?
