I doubt Warren Buffett is buying many stocks in this market. You would have made an absolute killing had you bought in in 2009-2012, but right now you might be buying at the top, just like bitcoin at $20,000. But we'll see. I haven't heard any really bad news that would suggest that the stock market might be in for a crash instead of a correction, but you never know.
Anything is uncertain neither on both stocks or crypto market. There would always be a sweet spot but we know we wont really able to get in on the right time due to hesitations and doesnt believe on possibilities.
We might able to say that we are on the top now when it comes to stock price but it might be possible it can shoot up on least we expect.Therefore, as a stocks trader if you do have insights of a certain stock then its up to you if we can able to risk or not.
