Stock market bubble warnings are everywhere. Here are the 10 most overvalued stocks.

• With the stock market hitting record highs, some investors are worried about a stock market bubble.

• High valuations and the AI hype cycle are the biggest concerns for bearish investors.

• From Artificial Intelligence to Chicken Wings, Here Are the 10 Most Valued Stocks on the Market Right Now

The stock market has hit record highs and the artificial intelligence hype has intensified, leading some investors to worry about a potential bubble.

With valuations stretched and cryptocurrencies booming, the S&P 500's rise of more than 25% since late October feels too fast for some investors.

Economist David Rosenberg highlighted three glaring divergences in the stock market earlier this month that suggest a downturn is inevitable, and Warren Buffett's favorite valuation signal is nearing an all-time record, suggesting that stocks are highly valued.

On an individual basis, it's not just AI stocks that are on the rise. From chicken-wing restaurants to biotech companies, valuations for all stocks are unsustainable over the long term.

Here are the 10 most highly valued stocks in the market today, with market valuations of at least $10 billion based on price-to-sales ratios.
