Warren Buffett, a big investor, owns a lot of Apple stock.
Recently, he sold a significant portion of it, around 13% of his stake, before Apple announced a huge buyback of its own stock.
People are wondering why Buffett is selling if he keeps praising Apple.
Some think he's trying to keep the stock price high while he sells more of it.
Apple's latest financial report showed a decrease in revenue, and there's uncertainty about its future growth.
They're planning to use $110 billion to buy back their own stock, which could make their remaining shares more valuable.
Buffett mentioned he sold some shares to avoid higher taxes in the future.
But the performance of Apple's stock also matters to him. If he thinks the stock will go down, he might sell more.
In simple terms, Buffett is selling some Apple stock, possibly because he thinks it's a good time to do so.
Apple's future isn't certain, but they're trying to boost their stock price by buying back shares.
