“Our proprietary UBS Evidence Lab study is positive for Apple,” wrote Steve Milunovich in a note to clients Tuesday.
Positive for Apple, negative for Samsung.
Among the findings of a four-country survey 4,000 smartphone owners:
- About 40% of respondents said they were likely to buy an iPhone 6 in the next year.
- Over half were leaning toward the higher-margin iPhone 6 Plus, compared with 38% for the iPhone 6.
- Demand in China was particularly high with 29% indicating they were very likely to buy the latest iPhone.
- More striking is Apple’s retention rate in China, which at over 80% “soars above Samsung and domestic brands” (see bar chart below)
- Over 70% of iPhone 6 buyers say they are at least somewhat likely to use Apple Pay.
- Almost one-third of interested iPhone buyers currently own Samsung phones, foreshadowing “significant share gain for Apple.”
.
“This share shift is stunning,” writes Milunovich. “Typically in CIRP surveys about 15-20% of iPhone buyers are migrating from Samsung.”
Milunovich, who rates Apple a buy, raised his price target Tuesday to $125 from $115.
“Apple has captured the most valuable real estate in the world,” he concluded, “a position in the minds of consumers.”
