Everyone knows that online advertising pays for a massive chunk of the internet that people know and love, whether it's social networking sites, news, photo sharing apps, or anything else. But how do the ads get delivered to your desktop or phone? On this week's Odd Lots podcast, we speak to Afsheen Bigdeli, an engineer who works on online ad platforms about how every time you see an ad it's the result of a virtually instantaneous online auction in which the seller of ad inventory (a publisher) and a buyer of ad inventory meet at an exchange, not totally unlike exchanges used for financial markets. It turns out there's a lot we can learn about financial market structure based on these rapid transactions.

Earlier this year, markets were spooked by blow-ups in a number of volatility-linked products. But dealing with volatility is the foundation of risk management on Wall Street and there's a particular model that's become pervasive among big investors and banks -- so-called Value-at-Risk (VaR) models seek to gauge how much a portfolio might gain or lose based on historic price movements. On this week's episode of the Odd Lots podcast, we speak to one of the original creators of VaR. Till Guldimann explains how he came up with the model while at JPMorgan, plus how it works, its limitations, how it can be gamed, and what he thinks of the volatility landscape now.

A pivotal moment in U.S. political history is when CNBC's Rick Santelli went on a gigantic rant against Obama's stimulus programs while on the floor of the Chicago Board of Trade. The rant is credited by some as having helped galvanize the Tea Party movement, which rapidly became highly influential within the Republican party. Standing next to Santelli was a floor trader, Eric Wilkinson, who joined along in the rant, and become a player in his own right in the story. On this week's episode, we talk to Wilkinson about his background, the day of the rant, and how a conversation that he had had earlier that morning with Santelli influenced that moment.

Longtime market analyst Ed Yardeni came up with the term "Bond Vigilantes" to describe the way bond market participants can punish governments who run economically irresponsible policies. When Yardeni used it in the 80s, it referred to US fiscal policy that was thought to be inflationary. Now the bond vigilantes are back, but this time they're in Italy. On this week's podcast, Yardeni explains the history of the term, what's going on now, and how interest rates can be used to model stock market valuations.

This year, the event was held for the first time in London, where Odd Lots joined a team from Goldman Sachs to compete for the prestigious title. In this episode, find out what it's like to actually compete in the fiendishly difficult experience that is Midnight Madness.

The recent trade tensions between the Trump administration and China has shone a light on the country's ambitions to become a technology powerhouse, as one of the complaints is that China unfairly extracts intellectual property from multinationals entering that market. But what, specifically, is China's long-term plan? On this week's Odd Lots podcast, we speak to Dan Wang, a technology analyst at Gavekal Dragonomics about the the Made In China 2025 initiative, which seeks to turn the country into a tech leader (in areas like semiconductors, medical equipment, clean energy, and wide-body aircraft) by the year 2025. Dan explains how the program works, where it's succeeding, where it's struggling, and what the ramifications are for the rest of the world.

When Bitcoin first began generating headlines, there were some who thought the cryptocurrency was a fraud and others who thought it was the next big thing. Greg King, CEO of Rex Shares LLC, was one of the latter. Like the Winklevoss twins, he set out to create an exchange-traded fund (ETF) that would allow people to invest in Bitcoin in a new way. But many years later, the U.S. securities watchdog hasn't approved such plans. On this edition of the Odd Lots podcast, we use the Bitcoin example and King's experience to explain the inner workings of ETFs.
