The lockdown is leading to new bad habits
Napi.hu (Hungarian) online
Easy access to trading through new apps can lead traders to take more risks when buying and selling stocks. Research co-authored by Prof. Terrance Odean, the Rudd Family Foundation Chair, found that overtrading leads to losses, while patience pays off.
Disappointed GameStop Traders Should Take These Lessons to the Next Mania
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
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.
Bored Lockdown Traders Are a Danger to Themselves
Constantly checking your portfolio is likely to be bad for your long-term returns as well as your short-term mental health. Research co-authored by Prof. Terrance Odean, the Rudd Family Foundation Chair, found that the most patient investors outperformed the most active buyers-and-sellers by 7 percentage points per year.
UC Berkeley professors, community react to Gamestop stock prices
The Daily Californian online
Prof. Terrance Odean, the Rudd Family Foundation Chair, said one unique detail about the recent GameStop furor is the degree to which nonprofessional investors used premeditated collective action to push share prices up.
How Does the GameStop Squeeze End?
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."
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.
Trading Stocks Has Never Been Easier. Here’s How Often Experts Say You Should Buy and Sell
Even as trading behavior changes with technology and generational habits, how often is "too often" to trade will vary depending on an individual's risk tolerance and net worth. Research by Prof. Terrance Odean, the Rudd Family Foundation Chair, found that those who traded the most underperformed the market by a whopping 6.5 percentage points every year.
Why men are more likely to invest in Tesla
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
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.
Rally democratizes ownership of rare collectibles, but investors should solely focused on ROI should avoid
A new app called Rally allows people to buy fractional shares in sports memorabilia and other rare collectibles, such as Clint Frank's 1937 Heisman Memorial Trophy. Finance Prof. Terrance Odean, the Rudd Family Foundation Chair, says these aren’t opportunities that non-accredited investors should be pursuing “unless the [individuals] were getting entertainment value from investing in addition to the possibility of a profit or loss, and were spending entirely discretionary funds.”
Winning or losing, staying in the game is the thing for some investors
Business Day online
Prof. Terrance Odean, the Rudd Family Foundation Chair, says individual investors mostly buy stocks that catch their attention, such as stocks with volatile price moves or that have made big headlines. That's because individual investors aren't equipped to deal with the hundreds of options that are available to them daily.
Popular stocks on Robinhood beat the market: JPMorgan
Yahoo! Finance online
Robinhood's investors gravitate toward stocks that are in the headlines. Interest from retail traders had a greater impact on the performance of small- and mid-cap stocks than large-cap names. That's consistent with research by Prof. Terrance Odean, the Rudd Family Foundation Chair, who also found that the retail investor is a contrarian sell signal over the long term.
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.”
Women and trading: Currencies, commodities, and crypto
Enterprising Investor online
It's challenging for women who want to be traders, but things are changing. The author quotes Prof. Terrance Odean, the Rudd Family Foundation Chair, who noted that there are more women in the audience now when he speaks to groups of financial advisors and that his classes now have more women.
