Marijuana, meanwhile, is going mainstream. It’s perceived as healthier than alcohol by many Gen Z consumers and is now legal for adult use in 10 U.S. states. Gen Z consumers are coming of age in time when the decades of stigma around weed—think reefer madness—are fading away as more states legalize and stressed out, tired Americans look to cannabis compounds to alleviate insomnia and anxiety, or just unwind after a hard week of work.

Investors have two main options for betting on weed. They can invest in Canadian companies—think Canopy Growth Corp. and Aurora Cannabis Inc.—which benefit from federal legislation there but also are operating in a country with a population smaller than California.  There are also the so-called multi-state operators in the U.S., like Curaleaf Holdings Inc. and Green Thumb Industries Inc. The U.S. legal market is already larger than all of Canada’s, but federal prohibition creates hurdles for the American companies—and leaves some money managers wary of advertising their bets.

3. They Don’t Have to Go to Stores
Gen Z could be the first generation to truly embrace online grocery shopping—though maybe not yet. Just 83 percent of them said they primarily purchase groceries at a physical store, compared to 95 percent of baby boomers and 87 percent of millennials. Surveys have also indicated that Amazon is one of the favorite brands of Gen Z consumers, who’ve never lived in a time without the e-commerce giant.

It’s worth noting that the oldest members of Gen Z are barely out of college by most measures, not exactly peak grocery-buying age. Still, they’ve grown up in a world where digital shopping is ubiquitous. As of now, a tiny percentage of groceries are purchased online, because most people still want to touch their tomatoes. But since Amazon.com Inc. announced a deal to buy Whole Foods almost two years ago, Kroger and Walmart, the largest sellers of groceries in the U.S., have spent billions investing in technology and keeping prices low as they brace for the digital invasion. Whoever figures out the equation for grocery delivery—human-delivered or self-driving cars—will have a lot to gain.

4. They Choose Their Brand Loyalties Carefully
The rise of Gen Z could be bad news for traditional clothing retailers like Gap Inc. and Macy’s Inc., already battered by the shift to buying clothing online. The next generation is also embracing second-hand apparel, which will be bigger than fast fashion within the decade, according to Thredup’s 2019 Resale Report. Thredup, fashion resale website, says more than one in three Gen Z shoppers will buy used clothing this year, versus less than one in five boomers or Gen X consumers. That seems to stem, in part, from the generation’s interest in environmental issues and ethical shopping.

Apparel brands looking to connect with younger shoppers have tried embracing edgier brand ambassadors, a departure from the days when consumer companies went to great pains to avoid politics. That's because Gen Z actually wants corporations to take a stand on issues, with 40 percent saying they’d pay more for a product if they knew the company was promoting gender equality issues and 42 percent for racial justice initiatives.

Nike understands. Last year, it released an ad featuring Colin Kaepernick, and while the inclusion of the controversial quarterback-turned-activist initially spooked investors, the shares have since rebounded. And there are indications that ads have helped boost sales.

“A lot of times in this industry people want to overcomplicate the process of picking stocks,” Exponential ETFs’ Bak said. “We think that there’s a pretty high correlation between companies that from your personal experiences you think are good and high-growth companies.”

5. They Eat (Somewhat) Differently
Gen Z consumers are more likely to skip meat than the older U.S. cohorts, the latest dining disruption with big implications for fast-food restaurants and packaged-food giants. Burger King this week announced a test of a plant-based Impossible Whopper, another sign that even the purveyors of indulgent onion rings and big burgers see a shift ahead.

Just a few years ago, the narrative was that millennials were killing off traditional fast-food chains, opting instead for the so-called fast casual competitors like Chipotle Mexican Grill Inc. and Panera Bread that were promising higher quality and cleaner ingredients with the same quick convenience. It’s true that eating habits have shifted, but old-school burger chains like McDonald’s Corp. and Burger King still dominate in the restaurant industry. McDonald’s has bounced back from a sales slump, thanks in large part of all-day breakfast, and recently invested $300 million in a technology company it says will help boost drive-thru sales. It turns out even today’s teens still want fries with that.
