Understanding Market Demand Elasticities in Stock Trading

In this episode, we sit down with Professor Valentin Haddad to unpack the intricacies of market elasticity, passive investing, and the dynamic nature of financial markets. Valentin is an Associate Professor of Finance at UCLA Anderson School of Management and a research fellow for the National Bureau of Economic Research’s Asset Pricing Program. His research focuses on how financial institutions trade, and manage risk, and their impact on market prices and the broader economy. Notably, his work challenges traditional assumptions, such as the perceived safety of life insurance companies' investments in Treasuries. In our conversation, we delve into the impact of index funds on the market, stock market bubbles around the development of new technology, and the response of investment-grade corporate bonds to the COVID-19 crisis. Discover the definition of demand elasticity, strategic interaction, and how market elasticity has changed over time. Explore how he defines a market bubble, ways stock market bubbles are related to new technology, and how to measure the value of innovation. We also discuss the impact of COVID-19 on investment-grade corporate bonds, the Federal Reserve’s response, the implications for bond safety, and much more. Tune in and join us as we uncover the mess of the market with Professor Valentin Haddad!

Quotes:

“You choose how you trade based on how other people are trading. So, it's not really just what you like to do, but how you react to others in the market.” — Professor Valentin Haddad (0:06:40)

“If nobody's acquiring information, then markets are very inefficient. Then, you should step in, in a way. So, if everybody is becoming passive, there are more gains for being not passive.” — Professor Valentin Haddad (0:22:59)

“Speculation often comes with innovation.” — Professor Valentin Haddad (0:28:30)

“I think these concerns with passive investing are meaningful. I don't think it's quite yet the time for a very strong regulatory call. Regulators should keep track of this evolution.” — Professor Valentin Haddad (0:31:42)

“You can gain from bubbles, but at the end, the end of the bubble comes. The long-term gains of innovation are still there, but many people who partake in the bubble are going to suffer a lot.” — Professor Valentin Haddad (0:43:57)
