Haas study sheds eerie light on fright and financial decision making

October 28, 2011

Watching a horror movie can scare you into selling your stocks earlier than you would have otherwise. That’s the frightening evidence shown in a series of studies by Associate Professor Eduardo Andrade and Chan Jean Lee, a PhD candidate, both in the Haas Marketing Group.

Lee and Andrade are the co-authors of “Fear, Social Projection, and Financial Decision Making,” forthcoming in a special issue on consumers’ making in the Journal of Marketing Research, November 2011.

The article explains that the scared investor’s early decision to sell stocks happens through “social projection”—people’s tendency to heavily rely on their own current feelings and inclinations when they estimate others’ state of mind and preferences. As a result of social projection, an investor who is scared assumes that other investors are also scared and that their fear will consequently drive the stock price down, prompting the one investor to sell early before the price sinks.

“If I’m scared, I tend to project that you are scared,” Andrade explains. “If I feel like selling, I project that you are also going to sell, and that pushes me to sell earlier rather than later in anticipation of a drop in stock value.”

Lee and Andrade set out to manipulate the participants’ emotions in a way completely unrelated to the stock market. They created two random groups. One group watched clips from horror movies such as “The Sixth Sense” and “The Ring.” The other test group watched documentaries about Benjamin Franklin and Vincent Van Gogh containing material not intended to illicit emotion. After the screenings, researchers told the participants that it was time to move onto another experiment, a stock market simulation.

In the simulation, participants went through 25 rounds in which they had an opportunity to sell a $10 stock (part of their participation fee). The rules of the market stated that prices would decrease if any participant sold his or her stock, and prices would increase if every player held onto their stock. Each simulation involved approximately 26 anonymous participants and therefore, prices could go up or down in any given round.

Selling patterns indicated that the scared players, that is, those who watched the horror movies in the previous task, were more likely to sell early in the game than those who watched the documentary films. Put simply, an incidental induction of fear triggered selling behavior. In order to test for the role of social projection, Lee and Andrade added a few twists. They reasoned that if social projection is a key mechanism during the process, the impact of fear should be reduced when people are less likely to try to project what others will do.

Consistent with this hypothesis, fear promoted early selling only when participants were told that the value of the stock was peer-generated. When participants were told that the value was randomly determined by a computer (where social projection is not a factor), the fearful experienced derived from watching the horror movie had no impact on their decision.

The final study of the article found that early sell-off occurred when the investor was told that others shared in his or her risk attitude. At the same time, when the investor was told that his or her risk attitude was very unique in the market, the resulted tended to reverse.

Andrade says the study suggests that controlling the influence of fear in financial decisions can be profitable. “Generally speaking, those who made more money were those who decided to stay longer in the simulation game.”
