Smartphone price drop: Is this when it starts?
Are we seeing the beginning of falling smartphone prices?
That's the question doing the rounds after news broke last week that U.S. mobile network operators and retailers are lowering the price of Blackberry's latest Z10 phone to as low as $49 with a service contract, from $199 four months earlier.
According to a research note from Macquarie, manufacturers of high-end smartphones may be forced to lower prices in the coming months, as the market nears saturation and users slow the pace of changing phones.
"We expect high-end smartphone demand to gradually plateau and price competition to intensify from the second half of 2013," analysts at the bank wrote in a report published late Thursday.
"High penetration rates in most developed countries and consumers' lengthening replacement cycles are causing a slowdown in sales growth of several leading smartphone brands," they said.

With high-end smartphones likely to account for a smaller share of overall smartphone sales, this is also negative for companies operating in the supply chain, the bank warned, noting that component makers are already facing production cuts.
"(China-based LCD manufacturer) Tianma, for instance, has started seeing order cuts, and most companies are seeing decelerating growth and potential disappointment amidst high smartphone penetration," the analysts said.
For investors in the smartphone component space, the bank recommends avoiding companies with exposure to the high-end segment, in particular Taiwan-listed contract manufacturer Hon Hai, camera-lens maker Largan, South Korea-listed LG Innotek and Hong Kong-listed acoustic components maker AAC. These firms are vulnerable to a slowdown in orders from Apple and Samsung, the note said.

Macquarie forecasts Apple's next iPhone, expected to be released as early as September, to sell just 48 million units in the second half of 2013, down from the iPhone 5's 63 million in the same period last year.
It added that sales of HTC's award-winning HTC One smartphone is also likely to disappoint, expecting shipments to drop to as low as 1.8 million units in the third quarter against forecasts for 3 million, down from 3.5 million in the second quarter.

Earlier this month, Samsung released its second quarter earnings estimate which failed to meet analysts' expectations, hiking worries that the market for smartphone makers could be reaching saturation.
