Commentary: The Market Psychology of Unexpected Disasters As can be seen in the CCJ example, It wasn't until Monday March 14, and again on Wednesday March 16, that investors reacted to the risks - such as radiation - that had emerged from the Japanese earthquake and tsunami. "What took them so long to wake up to the risks?" is a fair question to ask. Below I explain the psychological stages which drive investors and financial markets after unexpected events such as natural disasters and terrorist attacks. The psychological response to such events follows three stages. Stage 1: Underreaction. In this stage people don't realize the scope of the disaster. They believe the stock rally will go on as is, and they believe the official assessment of the situation - that all are safe. This is a good time to be skeptical and to sell or short. Psychological Driver: Cognitive Dissonance and Denial. People have trouble processing new information that is out of their comfort zone. They need time to reconcile new facts with their established habits and beliefs, especially if they do not feel an immediate ongoing threat. Stage 2: Reaction. . Investors realize that significant dangers have emerged, and they take action. The Nikkei drops 14% in one day. The S&P 500 sheds its 2011 gains. This occurred in the second and fourth trading days after the earthquake. Fund managers sold the stocks of companies that were likely to be impacted negatively by supply disruptions and bought shares of those likely to benefit. Psychological Driver: Rational Reappraisal and Arousal to Action. We incorporate the new facts, and revalue securities accordingly. Stage 3: Overreaction. This is where the situation gets interesting. Uncertainty and fear color investors' assessment of the facts. Due to rapid changes in the nature and immediacy of potential threats, investors indiscriminately unwind their risky positions. Stress hormones narrow investors' abilty to see long term, and they begin to follow every news announcement with increasing worry. Stocks sell off, Potassium Iodide (KI) sells out off store shelves in California, and people sell their stocks because prices are dropping and the situation is unclear. This is when indiscriminate risk selling occurs. Psychological Driver: Fear, uncertainty, and feeling out of control. Radiation cannot be seen, is widely feared, and may spread beyond Japan. Perhaps most worrisome to investors, during the crisis there was no trusted authority who could explain the facts coherently - the Japanese government appeared to either not understand the situation or to be trying to prevent panic by hiding the true impact of events. All of those factors led to loss of trust and overreaction. Such overreaction usually occurs about 4-5 days after a crisis and is seen as panic, when all risky assets are sold and safe assets are hoarded (even iodized salt sold out in many parts of China). Real investment bargains emerge at this time. it was a good time to buy Japanese construction and insurance stocks. While we've explained the stages of such a crisis, and the opportunities that emerge in each, our thoughts are with the victims in Japan. We extend our sincere condolences to all whose family, friends, or lives have been affected by this terrible series of events. |
