One of Wall Street’s top analysts, Gene Munster at Piper Jaffray is chiming in on Apple Inc. (NASDAQ:AAPL) and, Inc. (NASDAQ:AMZN) after respective results from Fall 2016 Teen Surveys have the analyst maintaining bullish forecasts for both giants.

Munster has an excellent TipRanks score with a 67% success rate and he stands at #6 out of 3,821 on the analyst leaderboard. When recommending AAPL, Munster earns 12.2% in average profits on the stock. When suggesting AMZN, Munster gains 39.7% in average profits on the stock. Let’s take a closer look:

Apple Inc.

Munster notes Apple is in good standing after his most recent Teen Survey looking at smartphone ownership among 10,0074 respondents has indicated the tech titan’s share of teens who own smartphones has spiked. This past spring, 69% of teens had an iPhone and 75% anticipated their next device would be an iPhone. Presently, those numbers have jumped to 74% and 79%, respectively.

In reaction, the analyst reiterates an Overweight rating on shares of AAPL with a $151 price target, which represents a 29% increase from where the stock is currently trading.

Munster notes, “While we don’t view the iPhone 7 as significant as an upgrade as the iPhone 6, we believe this is a positive data point on how consumers are viewing the new device. Overall, we view the Teen Survey data as a sign that Apple’s place as the dominant device brand among teens remains intact.”

Furthermore, tablet ownership has also surged among teens, rising from 59% in the spring to 62%, a boost of which has not been seen in tablet ownership since Munster’s Fall 2014 survey.

“We continue to view the tablet market as largely saturated, particularly at the high-end. We believe comps will remain easy for iPad over the next few quarters, but don’t necessarily expect that to translate into meaningful growth,” the analyst contends.

TipRanks analytics exhibit AAPL as a Strong Buy. Based on 36 analysts polled in the last 3 months, 31 rate a Buy on AAPL, 4 maintain a Hold, while 1 issues a Sell. The 12-month average price target stands at $129.61, marking a nearly 11% upside from where the stock is currently trading.screen-shot-10-14-16-at-03-07-pm, Inc.

Munster sees Amazon continuing to capture mindshare. After his Fall 2016 Taking Stock with Teens Survey that polled over 10,000 teens in the U.S. revealed the online streaming giant is the favorite eCommerce website among 40% of teens coupled with sustained Prime adoption across demographics, Munster remains positive on Amazon. From the analyst’s results, the survey indicates that middle-quintile income households show the most considerable penetration upturn.

In light of the survey results, Munster reiterates an Overweight rating on AMZN with a price target of $900, which represents just under a 9% increase from current levels.

Why is this significant? Munster explains, “For context, mindshare in our Taking Stock with Teens survey has historically not broken above the low 30% range for brands/retailers and, therefore, the fact that Amazon is maintaining at 40% mindshare is encouraging.”

“58% of respondents indicated their family has Prime, which is 11ppts higher than our Fall 2015 survey and indicates the quick pace of Prime growth. Our survey is a snapshot of the population, which when taken in concert with other surveys we have done would indicate that the number of US Prime households would be in the low/mid-60M range. This scale is crucial, as it makes it very difficult for competitors like Wal-Mart to upset consumer habits in our view,” Munster concludes.

TipRanks analytics demonstrate AMZN as a Strong Buy. Based on 34 analysts polled in the last 3 months, 33 rate a Buy on AMZN, while 1 maintains a Hold. The consensus price target stands at $928.28, marking a nearly 12% upside from where the stock is currently trading.screen-shot-10-14-16-at-03-08-pm
