Apple’s stock could underperform, especially without an ‘all-glass’ iPhone, this analyst warns

Apple might face challenges in driving up its stock performance if it doesn't introduce a highly anticipated "all-glass" iPhone, according to a Jefferies analyst. The analyst suggests that Apple's strategy to increase profitability by launching more expensive gadgets could be harder than expected. This could matter significantly as the iPhone series is a major revenue driver for the tech giant. The implications suggest that Apple's ability to innovate and meet consumer expectations could directly impact its financial health and market standing.
