What if there were a rolling paper that let you put the entire marijuana industry into a tightly packed joint? There is, and it's called an exchange-traded fund.

While more and more states legalize medical and recreational marijuana in the U.S., the federal government still classifies it as an illegal controlled substance. But that certainly doesn't make it illegal to invest in the industry, and certain publicly traded companies in the sector have seen their valuations soar of late. Most of these companies also happen to be based in Canada, a country that just legalized recreational marijuana last month. 

Bloomberg News reporter Rachel Evans takes a field trip to Toronto for a closer look of the nascent industry and a better understanding of the ETFs investors are using to gain exposure. She also joins Eric and Joel to discuss why investors should proceed cautiously in such a seductive space.

Where does a medical cure come from? 100 years ago, it wasn't uncommon for scientists to test medicines by taking a dose themselves. As medical technologies get cheaper and more accessible, patients and DIY tinkerers are trying something similar—and mainstream medicine is racing to catch up. Prognosis explores the leading edge of medical advances, and asks who gets—or should get—access to them. We look at how innovation happens, when it fails, and what it means to the people with a disease trying to feel better, live longer, or avoid death.

Acronyms are a popular way to shorthand especially promising emerging markets. Take the BRICs: Brazil, Russia, India and China. Or how about MIST: Mexico, Indonesia, South Korea and Turkey. And here's a new one from Bloomberg Intelligence: Africa's CUTEs, for the Democratic Republic of Congo, Uganda, Tanzania and Ethiopia. These catchy terms tend to make buzz because investors see such vast economic potential in these countries -- but where there's potential, you'll also find risk.

Ahead of Bloomberg's New Economy Forum in Singapore on Nov. 6-7, Joel and Eric take a tour of these potential growth engines with VanEck emerging market analysts Patricia Gonzalez and Ola El-Shawarby.

The creation story of the first exchange-traded fund is actually the best way to understand how they work. And it's not just educational, it's entertaining. Like the PC and the MP3, the story of the creation of SPY -- which turned 30 this year -- is full of characters, twists and turns, and subplots. In the end, the product launched an industry that's reshaping not just investing but the entire financial ecosystem. This six-episode miniseries will weave together interviews with the founding fathers and other key players that help investors better understand the ETF and how we got here.

With many of the world's stock markets in turmoil, and interest rates on the rise in the U.S., it can be hard to spot investment opportunities. A popular Bloomberg article asks six experts where they would invest $10,000 right now. Some of those areas include Asian countries, tobacco stocks, companies profiting from the mobile payment trend as well as just a plain ol' broad market allocation. 

On this week's Trillions we speak to the author of the story, Suzanne Woolley, and personal finance writer Ben Steverman about these picks as well as the ETFs that can be used to play them. We also discuss what they are hearing from retail investors outside the financial bubble about the recent selloff and investing in general.

Neeeeeeerrrrrrddsss! The term used to be an insult but now it’s (mostly) a compliment. At least that's the case in the world of ETFs, where passions run high for these low-cost, liquid funds. Used by long-term retail investors and institutional traders, there's a wide range of opinion on which Exchange Traded Funds are best, which trends are smart and what the future may hold.

On this week’s Trillions, Joel and Eric spar with a colorful gang of ETF pundits in a McLaughlin Group-style roundtable. They discuss 20 hot issues in the ETF world, including whether fees are overrated, when a zero-fee ETF will arrive, whether ESG funds can ever find an audience, where innovation will come from and what ETF our panelists would use for their life savings.

While the rise of ETFs has been good for ETFs, it has come at the expense of many mutual fund managers -- humans who have seen about $1 trillion in outflows over the past four years. The situation has confounded many active fund companies and fueled consolidation in the industry. Now, a prominent active fund advocate and ETF critic says he’s found a better strategy: mutual funds with performance-based fees.

On this episode of Trillions, Joel and Eric speak with Peter Kraus, former CEO of Alliance Bernstein, who discusses his new endeavor, Aperture Investors; also joining the conversation is Sonali Basak, a finance reporter with Bloomberg News. Kraus plans to offer actively managed mutual funds that cost about the same as a passive ETF -- unless his portfolio managers outperform their benchmarks and generate alpha. Aligning compensation with performance, Kraus says, is a better incentive than charging a fee based on assets under management. The episode also covers shortcomings of the ETF, why active management needs a dose of creative destruction and how a portfolio might benefit from performance-linked fees.

Ten years ago, the financial crisis changed everything -- and helped create the world we now inhabit. Eric and Joel push rewind to revisit 2008, examine why ETFs managed to take in money that year despite the huge loss in the market, and dissect what's changed in the decade since and what it tells us about the future. Christine Harper, the editor of Bloomberg Markets, who covered banking for Bloomberg News at the time, joins to offer her insights.
