In Apple‘s (NASDAQ: AAPL) most recent quarter, revenue in Greater China, which includes China, Hong Kong, and Taiwan, was down 12% year over year. With the operating segment accounting for about 21% of Apple’s total revenue, it’s no surprise some investors are concerned with Apple’s performance in the market. After all, this is a far cry from the segment’s high growth in the past. In the first quarter of 2016, Greater China revenue increased 14% year over year, growing faster than any other market.
