Amazon and Tesla take off as small investors embrace fractional-share trading

The Wall Street Journal  online


Popular companies like Tesla are getting a boost from the quarantine rise of fractional trading, popular with millennials. Prof. Terrance Odean, the Rudd Family Foundation Chair, did foundational research in how overtrading is not a good long-term strategy. But he's not that worried. “Will this encourage some speculation? Probably some,” he said. “But it’s going to be speculation with a lot less money than if people were forced to buy whole shares.”

MSN Money  online


"Thus, the effect of COVID-19 on real estate, both residential and commercial, will not be evenly distributed. Cities with more resilient industries will have more resilient real estate.

Shares by the slice: Fractional investing sparks a stock market stampede

Washington Post  online


Fractional investing, popularized by stock-trading apps like Robinhood and SoFi, has surged during the pandemic. Prof. Terrance Odean, the Rudd Family Foundation Chair, says the strategy might lower risk, but is an unlikely path to long-term wealth. "The very fact that they are a fraction of a share means they are rarely a lot of money,” he said. "Fractional shares make it easier to be diversified, so you probably don’t have a lot to lose on any one company. But you probably aren’t going to get rich."

The lockdown death of a 20-year-old day trader

Financial Times  online


The suicide of Alex Kearns—who mistakenly believed he had lost heavily in a soured options bet he made on Robinhood—triggered calls for reform of online brokerages. Prof. Terrance Odean, the Rudd Family Foundation Chair, said more education is needed. "If it’s play money and money you can afford to lose, that’s your business. But you don’t commit suicide because you lost your play money," he said.

Women trade less often than men, with better results

Financial Times  online


A seminal study on trading behaviors by Prof. Terrance Odean, the Rudd Family Foundation Chair, tested whether overconfident investors were more likely to trade shares. Because men tend to be overconfident in traditionally male-dominated arenas, such as finance, gender was used as a proxy for confidence. "We don’t find that women make better trading decisions, they just make fewer bad ones," Odean said.

Women won't achieve true power until we start talking frankly about money

Newsweek  online

He found men often fall prey to impatience and overconfidence, making them trade 45 percent more than women, who tended to be buy-and-hold investors.

Investors' fear of flying

OZY  online


A few things are making small traders wary these days, including a growing realization that just because there's a lot of information out there, they may not know everything they need. “If you give the average investor all the data for a company, can they do the same fundamental analysis as a guy who went through a Ph.D. program and works at Goldman Sachs? It’s just an illusion of a level field," said Prof. Terrance Odean, Rudd Family Foundation Chair.
