In my opinion, we are in a bubble now. In stocks, P/E ratios are extremely high, and many companies are IPOing, many more than two years ago. All asset pricing is going through the roof, and money is chasing money. Speculative assets have become trendy again with cryptocurrencies, ARK, and memes like dogecoin.
We're all flush with cash and either terrified of inflation or riding a euphoria of asset inflation.
