Build Your Own Target-Date Fund

The Street  online


Retirement investors can save money on fees and improve performance by building their own target-date fund. “Many retirement accounts have limited—and high fee— offerings,” said Prof. Terrance Odean, the Rudd Family Foundation Chair. “In many such cases, an investor won't have the option of substituting low fee ETFs for high fee target-date funds,” he said.

Disappointed GameStop Traders Should Take These Lessons to the Next Mania

Bloomberg  online


Some investors in GameStop are now lamenting the fact that they got pulled into a “cult mentality” and hung on to the stock for too long. Prof. Terrance Odean ran a classic study in the late 1990s looking at the “disposition effect,” which he described as “the tendency of investors to hold losing investments too long and sell winning investments too soon.” With the exception of December, when people are thinking about the end of the tax year, Odean’s paper found that individual investors “realize their profitable stocks investments at a much higher rate than their unprofitable ones.”

‘Overconfidence’: Why it’s mostly men under 30 trading bitcoin

MarketWatch  online


Research co-authored by Prof. Terrance Odean, the Rudd Family Foundation Chair, found that men trade stocks 45% more frequently than women, a symptom of overconfidence. In 2001, when the study was done, these findings manifested in lower investment returns for men due to brokerage trading fees. In 2021, it may be extended to men getting involved in dangerously speculative rallies, the writer argues.

How Does the GameStop Squeeze End?

Gizmodo  online


Prof. Terrance Odean, the Rudd Family Foundation Chair, said GameStop's stock price will likely drop significantly. "However, there is no hard fast rule about how fast the drop comes," he said. "A stock can stay overpriced relative to fundamentals for a long time. Most likely that will leave owners disappointed in future gains, but that can take quite a while. GameStop is unusual because of how much investor attention it has on both sides."

Democratising finance

World Finance  online


Investment platforms like Robinhood are making it easier for ordinary people to invest. But their mission has left many novice traders navigating complex markets without sufficient protection, argues this writer, who cites a 2000 paper entitled "Trading is hazardous to your wealth," by Prof. Terrance Odean, the Rudd Family Foundation Chair.

Why men are more likely to invest in Tesla

MarketWatch  online


New research has found that male investors are more inclined to pursue momentum strategies, while female investors tend to be more contrarian. Prof. Terrance Odean, the Rudd Family Foundation Chair, said he had not analyzed data in the new study, but speculated that men are more aggressive than women in chasing investment performance. This is consistent with Odean's research, which found that men are far more confident in their trading abilities than women. This leads them to trade much more frequently—and lose more money as a result.

Herding by ‘Naive’ Robinhood Traders May Be Good Signal to Short

Bloomberg  online


Traders using the "millennial-friendly" app Robinhood—the first to offer commission-free trading—are more likely to chase popular stocks with extreme performance. The resulting "herding" becomes a drag on those companies' returns and leads to the reversal of nearly 5% over the following month, according to new research by Prof. Terrance Odean, The Rudd Family Foundation Chair. "Robinhood users are more subject to attention biases. The combination of naïve investors and the simplification of information is associated with herding episodes," he writes.
