Investment giant Berkshire Hathaway disclosed in a recent quarterly report that it has made substantial adjustments to its holding in Apple during the second quarter, reducing its shares from 789 million in the first quarter to approximately 400 million, which is almost 50%. This means that Berkshire Hathaway currently holds about 2.6% of Apple's shares, with a market value of around $88 billion based on the closing price of $219.86 last Friday. Although this reduction was expected in the market, the actual scale of the reduction exceeded the prediction of some analysts.
