The headlines were good. Apple reported fiscal third-quarter earnings and revenue that beat analyst forecasts. But, digging deeper, Apple's Achilles heel was plain for all to see: shrinking margins and slowing China sales.
Still, Apple's shares closed up 5 percent on Wednesday and many analysts dismissed the worries, pointing to signs the company is working on a cheaper iPhone that will help it better compete in emerging markets such as China and alleviate the margin pressures.
"There's a lot of speculation for this low cost iPhone that's coming, that potentially could be the majority of the fourth-quarter shipments," Steven Pelayo, regional head of technology research for Asia-Pacific at HSBC, told CNBC on Wednesday.

"They really do need to have a low-cost product… with a plastic case, instead of a metal one, [and] some other ways to save some cost there."
Apple has consistently hinted at several new product launches this Fall, and on Tuesday, CEO Tim Cook re-iterated that theme. "We are laser-focused and working hard on some amazing new products that we will introduce in the Fall and across 2014," Cook said.
Ian Fogg, head of mobile at research firm IHS Global Insight, told CNBC that Apple was weighing up lower price points in emerging markets to see how they affect shipments with an eye on future releases.
"This is a great bit of real world marketing research [going on]," Fogg said. "Does it cannibalize its higher end market or does it drive shipments? I think it will drive shipments."
In the meantime, Apple has been offering more affordable pricing in emerging markets in an attempt to boost sales. That's had a negative effect on average selling prices (ASPs). Peter Oppenheimer, Apple's chief financial officer, indicated that ASPs for the iPhone were down $27 year-over-year.

Gross margins for Apple's third quarter fell to 36.9 percent compared to 42.8 percent in the year-ago quarter.
Meanwhile, Apple's revenues in China, Hong Kong and Taiwan, which compose Greater China, fell 47 percent over the previous quarter and were down 14 percent year-on-year.
But, Benedict Evans of consultancy firm Enders Analysis told CNBC there were several issues surrounding Apple's slump in China, such as weaker economic growth and sales being strong in the previous quarter because of Chinese New Year. In addition, Apple sales in Hong Kong had been affected because the company was now distributing products directly to China and other regional markets, rather than via Hong Kong.
The company has also been boosting distribution in emerging markets, helping it to post a more-than 400 percent sales increase in India. Sales in Turkey and Poland were up over 60 percent and sales in the Philippines were about 140 percent higher.
But Apple, and other smartphone makers, also face a growing threat from low-cost multi-function phones, often called feature phones, that are now capturing a larger share in emerging markets.

"'Smartphone' is being redefined in developing markets. Increasingly it looks like a sub $100 device that is 'smart' enough. But this is a level Apple finds very hard to play in," Victor Basta, managing director of Magister Advisors, a boutique M&A advisor in the technology field, told CNBC.
"This world will belong to HTC and Huawei and others who can produce stripped-down devices. Apple's greatest fear in the region is that it stays that way even as the economies develop."
