Michael Douglass: Welcome to Industry Focus, the podcast that dives into a different sector of the stock market every day. It's Monday, May 21st, and we're doing a special episode on the so-called war on cash. Listeners, whenever you send in a question via email, Twitter, letter in the mail, really whatever, we try to either answer it in email or devote an episode to it. Cam from the U.K. asked, "What do you think are the three best stocks to own to benefit from the war on cash?" So, I figured we'd step back and think big picture for a minute.

The so-called war on cash is this idea that the world is gradually transitioning away from cash, or, at least, that it will in the future. Certainly, there's plenty of data out there showing that increasing proportions of people are using non-cash methods of payment: debit cards, credit cards, mobile transfer services like Venmo and the like. In fact, the BBC reported last year that cash was used in under 20% of transactions in Sweden, for instance. So, certainly, we've seen this movement.

But, the fact of the matter is, cash still reigns across the world. In fact, American Express recently highlighted this as an opportunity. They had this presentation in which they described just how much runway there is still to take over from cash.

Matt Frankel: There's a common misperception among American investors and consumers that the credit card market is getting kind of saturated. AmEx came out with statistics that said the uncapped payment market is actually pretty huge. Right now, there's about $12 trillion in consumer payments going through cards, and they think that the addressable market is actually $29 trillion, so more than double the current size. The commercial side of things, it's even more of an opportunity. Right now, it's about a $2 trillion market, and they think it could be a $19 trillion market. So, there's still a lot of room to move toward a cashless society, is the takeaway there.

Douglass: Yes. Even in Sweden, where it's roughly 80-20, there's still opportunity. But, in most places, we have a lot more going through in cash. The second piece then, of all of this, as we're thinking about this, is, what will they go to? If cash becomes less common, what are people going to spend with? Here in the U.S. and in Europe, the answer has been cash to debit/ credit cards to mobile payments in addition to debit/ credit cards. A lot of people argue in favor of the credit card stocks because they're expecting a similar move among other countries. Now, in my view, certainly, there's an opportunity for credit card companies, and there's reason to think that they have plenty of market to expand into. 

But it's increasingly clear to me that, particularly in the really high-growth emerging markets that we talked about last week, people are really moving straight to mobile payments from cash and bypassing credit cards to some extent. For example, according to Capgemini's 2017 World Payments Report, 50% of Chinese smartphone users are expected to adopt proximity mobile payments by 2020. 

So, we're bullish on credit card companies, at least I am. Personally, I'm a MasterCard shareholder. But we don't actually really see them as the best way to play the specific war on cash. So, here, we've put together three of our favorite stocks. The first one is Green Dot Corporation (GDOT 1.07%), ticker symbol GDOT.

Frankel: Yeah. On that note, I'm an American Express shareholder myself, and they're not the best way, we feel, because credit cards are expensive. The trend in financial technology, as we discussed in an episode a few weeks ago, is toward no fees. So, we're looking at companies that offer low-fee payment solutions, Green Dot being the first one.

They're a relatively small company. The market cap is just under $4 billion right now. And, in addition to a few other things, which we'll get to in a second, they're the leader in prepaid cards, where people have their paycheck directly loaded onto a prepaid card. You see all the prepaid Visa cards at the Walmart checkout, those are usually Green Dot products. Green Dot focuses on what are called the unbanked and underbanked segments of the population, meaning people who don't necessarily have a checking account. If you have, say, credit issues, you've defaulted on loans before, you've had charge-offs on checking accounts before, it can be really tough to get a bank account. These are the people who Green Dot focuses on. And a lot of the people who still use cash for everyday purchases are slowly transitioning to Green Dot product because it's getting less and less convenient to use cash. That's the best way I could sum up Green Dot -- it's a play on the inconvenience of cash over time.

Douglass: Yes. And, as you pointed out, it does a lot of things with a lot of different cards. It's interesting. I was not familiar with Green Dot until Matt pitched it to me a couple of days ago. And when I looked at the company, a couple of things really jumped out. The first one is that they have just really diversified revenue streams. If you look at the most recent quarter, out of roughly $315 million in revenue, about $130 million came from card revenues and other fees, $100 million from processing and settlement services, and then about $85 million from interchange revenues. So, what you see there is that they're playing in related areas, but they don't have all of their revenue really tied to one place, which is a really good thing to see.

The other thing is, you're seeing pretty impressive growth. Revenue last quarter grew by 16% on the organic side. Now, they actually had an acquisition which juiced revenue up further, but net of that, revenue grew by 16%. So, that's a really good sign that they've made a series of products that are really attractive to a lot of people.

Frankel: Green Dot, in addition to being an issuer of its own products, sees itself as more of a technology platform, whereas other companies can go and use their technology to offer financial services that suit them. Just a couple of examples, Walmart MoneyCard is a big, big partner of Green Dot. More recently, Uber has started issuing the Uber Debit Card through Green Dot's platform. Most recently, in December, Apple announced that it's using Green Dot's technology for its Apple Pay Cash platform. Which, you can't really get a better partnership than that, as far as peer-to-peer payments.

Douglass: Yes. It's interesting, because, the way Green Dot puts this is, it's banking as a service, or BAAS. You've probably heard of technology as a service, software as a service, etc. They're trying to comp themselves, I think, to a lot of these other companies. Essentially, what that means is, it's this mobile platform that can work in a lot of different areas. Now, whether or not you would really comp that to a tech stock is something that I think there could be a very healthy debate about. But, I think, what's very clear is, this is a company that's serving a historically underserved niche in the market and has really put together some really impressive growth with that.

Frankel: Yeah. The other two companies we're about to talk about focus on markets where people could use credit cards and things right now, it's just, they want to make it more convenient and less costly. Green Dot is focusing on people who don't have many other options. It's not too much of a big deal right now to carry cash. It's getting inconvenient in certain places. But, over the next few decades, it's going to start getting very inconvenient to use cash for certain things. And that's really why I like Green Dot as a long-term way to play the war on cash.

Douglass: Right. Alright, let's turn to our next stock, which is PayPal (PYPL 0.34%). Everyone knows PayPal as, well, PayPal. [laughs] Sort of like how everybody knows Facebook for Facebook. But, like Facebook, PayPal is also invested in other properties that are not its namesake -- chief among them, of course, Venmo. Which, if you're a millennial or know a millennial, you've probably heard about Venmo and how great it is for basically helping people not have to split the bill at restaurants.

Frankel: Yeah. I personally don't use Venmo, but I'm an older millennial. We'll chalk it up to that. I'm a millennial by about three months. [laughs] But, the statistics don't lie. Venmo payment volumes up 80% year over year. That's enormous growth. People think PayPal is kind of a mature company, but they're really not. Peer-to-peer payment volume, they're growing at a 50% year over year rate, and it's about a quarter of the total right now. So, PayPal is really not just eBay's payment processor anymore, which is where they were years ago. PayPal used to be part of eBay, if people aren't familiar. But, they're really transitioning into a new jack-of-all-trades payment company.

Douglass: Yeah. It's interesting. One of the things that PayPal execs always highlighted about Venmo -- and I had been skeptical about it -- is this idea that the social aspect is really a differentiator. If you use Venmo, basically, you send someone money, and you can give a reason that you're sending money. You can say rent, or brunch, or something completely ridiculous, if you want. And they really highlighted the social aspect of being able to see what other people are paying each other for as being a differentiator. I have been skeptical. But, I will note, John Rainey, PayPal's CFO, at a recent conference noted, and I'm quoting here, "The consumers that are using that are opening the app four and five times a week just to check the social feed." Now, I mean, is it just to check the social feed, or is it because they forgot what they were paying for? I don't know. But, it's certainly interesting to see that there's some data backing up that assertion. 

And, I mean, at the end of the day, a lot of people talk about different things like Zelle as potential competitors to Venmo. But the fact of the matter is, even with Zelle's launch, Venmo's growth has continued to accelerate, and they haven't seen any drawback. A big part of that is, Zelle, which underlies a lot of the banking, peer-to-peer payment apps, the average size of transactions on Zelle is a few hundred bucks, whereas for Venmo, it's more like upper 50s, low 60s, according to PayPal execs -- which is, again, a sign that you're using those apps for two different, complementary, things. So, they can both win in an increasingly mobile-first society.

Frankel: Another good thing about PayPal is, not only is the peer-to-peer side of their business doing really well, but their core business is still growing quite rapidly. They added over eight million new accounts in the first quarter alone, 15% more accounts than they did this time last year. So, their core payment business is really doing well, and people who are using PayPal are using it more. Per account, the average PayPal customer uses their account almost 35 times a year. That's an increase of about 8% from last year. So, their core payment business is doing really well in addition to their peer-to-peer business. And the core payment business, at least for the moment, is where they're making their money. That's the big revenue driver.

Douglass: Yeah, and that's one of the things that's sort of an opportunity and a danger for PayPal. At some point, they're going to want to try to monetize Venmo. And they've begun thinking about this a little bit with what's called pay with Venmo, which is essentially rolling things out so that people can use Venmo to pay merchants directly. So, certainly, there's some opportunity there. 

But, execs, I think very appropriately, have been very cautious in their outlook, and said, "Listen, we're not going to try to hit some amazing number on the revenue side with this and tank the whole experience," I think because they recognize that fundamentally, Venmo isn't a terribly sticky product. So, if you make things incrementally more difficult for really anybody in that chain -- from consumer-to-consumer to business -- then there may be a significant push to something else, whereas if you wait and allow that network effect to get stronger and stronger, it's going to become increasingly difficult for people to break away, and that's where there might be some monetization opportunity. But, that's years down the road.

Frankel: One more little thought on the monetization of peer-to-peer payments -- bear in mind how young that industry is. It was only about five years ago, people didn't think Facebook would be able to monetize its business. The point is, this is still in its early stages of evolution. There could be many different avenues they could take it to monetize payments without charging fees or things like that. It's a very, very young industry still.

Douglass: Yes, and a lot of opportunity there. Alright, let's turn to our third stock. By the way, I forgot to mention earlier, PayPal, that's ticker symbol PYPL. Square (SQ -2.28%) is our third one, which is ticker symbol SQ.

Frankel: Square is, in many ways, similar to PayPal. It's about one-fifth of the market cap. In terms of payment volume, it's a lot smaller. It's about one-eighth of PayPal's payment volume right now. While PayPal started out focusing on consumers paying businesses, Square is more of a small business-centered company. You can't walk down a craft market in America right now without everybody taking credit cards with Square payment readers. 

But, they're turning into so much more than that. They're really building, they call it omnichannel commerce. It's kind of a whole one-stop payment ecosystem for businesses, consumers. For example, they have a Square Capital platform that lends to small businesses, the Square Cash app, which is kind of what we're talking about with the war on cash. Their peer-to-peer payment app is the No. 1 app in the Apple App Store. So, they really transformed themselves from just the small business payment company to a small business and consumer ecosystem of payments. 

Other integrated features are what they're going for, with their Caviar food delivery app. They just acquired Weebly, which allows people to make their own websites, integrating that into their process so their customers don't have to go elsewhere to build their own e-commerce sites. Just, a lot of potential, and it's still within the early stages of figuring out how much of the business environment they could capture.

Douglass: Yeah. For me, I'm a Square shareholder personally because of the optionality. You look at Caviar, it's tiny compared to a GrubHub. It's distinctly possible that GrubHub or one of the various other food ordering services will continue to, pardon the pun, eat their lunch, because, you know, Caviar has a single-digit market share. But, long-term, maybe it can grow. Maybe it can differentiate. Maybe it can find some way to really succeed, particularly if they use it as an omni-channel, to use their terminology, cross-sell opportunity. 

They might charge a certain percentage to merchants who aren't using other Square services, but if they are using other Square services, maybe Caviar is free, maybe it's bundled, maybe it's a lesser percentage of revenue on the sold food that they're charging. So, there's a lot of opportunity, I think, if Square can really, really make entrepreneurship easy. And that's really what their goal is.

Frankel: Another thing with Square is, out of the three stocks we're talking about, they're the ones who are really embracing the whole cryptocurrency trend -- more so than the other two, anyway. You can now buy Bitcoin through the Square Cash app, if you talk about the ultimate war on cash. It's kind of still a small part of Square's business, but it's getting there, and it could become a big part if it's integrated into their small business solutions, whereas you can hold Bitcoin in Square Cash and use it at Square payment terminals, that could be a game-changer for the cryptocurrency world.

Douglass: Yeah, it's kind of a weird thing. It feels very different from pretty much everything else that Square is doing. But, again, this is a management that has unhesitatingly diversified, taken on opportunities. I think, in a lot of ways, they're just throwing a bunch of things out there and seeing what works. And that can be a bad strategy when it doesn't have a master plan behind it and an integrated experience that they're going for, or if it's just out of desperation. But Square has just been growing impressively. I think this is management's attempts to say, "OK, how do we take that growth, better monetize it, and build out that platform further and further, and stay ahead of the competition?" And thus far, Square really has done a good job of that.

Frankel: Yeah. This was the thesis on IBM a long time ago, in that the more parts of a company's business they rely on you for, the higher the cost of switching is. So, Square is turning into a very sticky business, to borrow a Warren Buffett term.

Douglass: Yes, indeed. Cool. Those are our three stocks, personally, my and Matt's favorite picks for the war on cash. Matt, of the three, is there one that stands out to you as your personal favorite?

Frankel: I own Square and PayPal. I owned Square when it was about the size of Green Dot, and it's really been nice to see where it evolved. I see that it has a whole lot more potential to grow, ultimately, to the size of PayPal, I could see it getting. Not that it will, I'm not saying that it will. But, I could definitely see Square doubling or tripling in size, even from here.

Douglass: Yeah. Square is the only one of these three that I personally own, so it's probably not surprising that it's the one I'm most bullish on right now. I usually try to buy companies that I like. [laughs] It sort of makes sense as an investor.
