For fund managers, Apple’s expanding stock market weight presents a challenge

Some fund managers are revisiting a difficult decision because of the significant increase in Apple’s stock price: they may not own enough of the stock.

Apple’s share price has increased 49% so far this year, bringing its market capitalisation to almost $3 trillion and increasing its weight in stock indices to record highs.

According to S&P Dow Jones Indices, the company’s weighting in the S&P 500 has increased to 7.6%, the highest of any stock in the history of the benchmark index.
