In a sign of the changing times, the S&P 100 is delisting Nike. To reiterate, the S&P 100 – not the S&P 500 – is delisting Nike, which is a reflection of the company’s poor performance on Wall Street and elsewhere. If you want to buy a share of the stock these days, it’s floundering around $38 to $40 per share, which is as low as it’s been in about 12 years. The delisting will take effect Sept. 21.
