Looks like Warren Buffett knows something or he just took his profits after invested to BYD for 17 years. He did an entire exit after selling all of his BYD stocks. This move of his have made a fall of 3% for the stocks of BYD. I guess that this OG move of Warren is stocking him pile of cash just like what he did last time when he's preparing for full cash mode. There seems to be a fall for many stocks soon and he'd buy them.
Warren Buffett’s fund exits BYD after a 17-year investment that grew over 20-fold in value
This does not necessarily mean that something is wrong with BYD. This could be because he has insider information relating to future US and China conflicts or other macro economic factors for which he wants to have more cash. Last year he sold TMSC too, did that prove that something was wrong with TMSC? No, it turns out the company is doing fantastic. Does the fond have investments in other major Chinese companies at this time? A 20 fold return over 17 years is pretty decent for stocks.
