Investing Basics: Six Ways to Outsmart Your Ape Brain
Don't let these common behaviors drive your investing decisions.
Over time, experts have identified the most common investing biases that stem from this primitive wiring -- the same inescapable “ape brain” functions that once kept us alive in the jungle. While some of these behaviors are more obvious in active traders, even casual investors can get caught up in emotions, says Smita Sadana, founder and chief executive of Sunrise Capital in Austin, Texas. And absolutely no one is immune to them. But once we know that we're guilty of committing an emotional bias, it can be easy to course correct -- or at least open our eyes to what we’re doing.
1. Don’t be a Victim of Your Last Success or Failure
Avoid: Recency Bias
One of the most common “ape brain” mistakes is to focus on your last few decisions rather than take the big picture into account, especially when your investments have taken a turn for the worse. “A few losing calls will cause precious many months of winning calls to be forgotten, since we tend to place more relevance on recent activities,” says Sadana. “This is a human defense mechanism that helps us cope with the past and pay more attention to recent activities, but in investing, such doubt causes grave results since it can impact the decision-making process.”
The Fix: Sadana recommends reassessing your action by taking a step away and allowing yourself to view the long-term situation in your portfolio.
2. Give Credit Where Credit’s Due
Avoid: Attribution Bias
Everyone likes to think that the good investing decisions were the result of their own smart thinking, and that the blame for the bad decisions (or losses) lies with someone else. But often, we really shouldn’t take the credit for either. “We tend to attribute positive outcomes to ourselves and negative outcomes to chance or outside factors,” says psychologist Brett Steenbarger, author of the blog TraderFeed. “Obviously, that can distort our decision making.”
The Fix: Take stock of everything you do at the end of each month or quarter and write down all of the things you did right, the things you did wrong, and what you can change, says Steenbarger. “Taking ownership of your strengths and weaknesses can help you become mindful of your trading processes,” he adds.
3. Remember to Get a Range of Opinions
Avoid: Diagnosis Bias
Each person views the world through their personal filter -- some are especially rosy, while others can be negative or pessimistic. The shade of your filter can have a major impact on how you invest or trade. According to Sadana, bulls tend to surround themselves with other bulls, while ignoring the bear view, and vice versa. “It’s an evolutionary trait, but unfortunately it can inject subjectivity in our diagnosis of the situation: We might not see the positive market action due to the fact that we paid attention to overly bearish commentary,” says Sadana.
The Fix: Try to bookmark websites and watch segments that are authored by people who have a different investing style than your own. Bring balance back to your worldview by surrounding yourself with a mix of commentary.
