Behavioral Biases: Symptoms and the Financial Damage Done

Congratulations to University of Chicago’s Richard Thaler for his recent Nobel Prize in economics! This isn’t the first time we’ve mentioned Professor Thaler. I referenced his work last year. And here, Rick Hill shared a conversation between Professor Thaler and fellow Nobel Laureate and University of Chicago colleague Eugene Fama. Thaler also is well known for his groundbreaking book, Nudge: Improving Decisions About Health, Wealth, and Happiness.”
Why do we keep mentioning the guy, and why does the Nobel committee agree that his work is worth recognizing? I can’t speak for the Nobel committee, but I can say that understanding Thaler’s many contributions to behavioral economics is essential to anyone who wants to Take the Long View® with their wealth. Just as financial economics focuses on how to best manage the market’s idiosyncrasies, behavioral economics focuses on how to curb our own behavioral biases, which often pose the greatest threat to our financial well-being.
When it comes to defending against your behavioral biases, forewarned is forearmed, so here’s a summary of some of our most damaging, if all-too-human traits.
The Bias: Anchoring
- Symptoms: Anchors aweigh! It’s easy for us to fixate and base ongoing decisions on an initial piece of information (the “anchor”), even if it’s no longer relevant to the decision at hand.
- Damage Done: “I paid $11/share for this stock and now it’s only worth $9. I won’t sell it until I’ve broken even.”
The Bias: Blind Spot
- Symptoms: The mirror might lie after all. We can assess others’ behavioral biases, but we often remain blind to our own.
- Damage Done: “We are often confident even when we are wrong, and an objective observer is more likely to detect our errors than we are.” (Daniel Kahneman)
The Bias: Confirmation
- Symptoms: This “I thought so” bias causes you to seek news that supports your beliefs and ignore conflicting evidence.
- Damage Done: After forming initial reactions, we’ll ignore new facts and find false affirmations to justify our chosen course … even if it would be in our best financial interest to consider a change.
The Bias: Familiarity
- Symptoms: Familiarity breeds complacency. We forget that “familiar” doesn’t always mean “safer” or “better.”
- Damage Done: By overconcentrating in familiar assets (domestic vs. foreign, or a company stock) you decrease global diversification and increase your exposure to unnecessary market risks.
The Bias: Fear
- Symptoms: Financial fear is that “Get me out, NOW” panic we feel whenever the markets turn brutal.
- Damage Done: “We’d never buy a shirt for full price then be O.K. returning it in exchange for the sale price. ‘Scary’ markets convince people this unequal exchange makes sense.” (Carl Richards)
The Bias: Framing
- Symptoms: Six of one or half a dozen of another? Different ways of considering the same information can lead to illogically different conclusions.
- Damage Done: Narrow framing can trick you into chasing or fleeing individual holdings, instead of managing everything you hold within the greater framework of your total portfolio.
The Bias: Greed
- Symptoms: Excitement is an investor’s enemy (to paraphrase Warren Buffett.)
- Damage Done: You can get burned in high-flying markets if you forget what really counts: managing risks, controlling costs, and sticking to plan.
The Bias: Herd Mentality
- Symptoms: “If everyone jumped off a bridge …” Your mother was right. Even if “everyone is doing it,” that doesn’t mean you should.
- Damage Done: Herd mentality intensifies our greedy or fearful financial reactions to the random events that generated the excitement to begin with.
The Bias: Hindsight
- Symptoms: “I knew it all along” (even if you didn’t). When your hindsight isn’t 20/20, your brain may subtly shift it until it is.
- Damage Done: If you trust your “gut” instead of a disciplined investment strategy, you may be hitching your financial future to a skewed view of the past.
The Bias: Loss Aversion
- Symptoms: No pain is even better than a gain. We humans are hardwired to abhor losing even more than we crave winning.
- Damage Done: Loss aversion causes investors to try to dodge bear markets, despite overwhelming evidence that market timing is more likely to increase costs and decrease expected returns.
The Bias: Mental Accounting
- Symptoms: Not all money is created equal. Mental accounting assigns different values to different dollars – such as inherited assets vs. lottery wins.
- Damage Done: Reluctant to sell an inherited holding? Want to blow a windfall as “fun money”? Mental accounting can play against you if you let it overrule your best financial interests.
The Bias: Outcome
- Symptoms: Luck or skill? Even when an outcome is just random luck, your biased brain still may attribute it to special skills.
- Damage Done: If you misattribute good or bad investment outcomes to a foresight you couldn’t possibly have had, it imperils your ability to remain an objective investor for the long haul.
The Bias: Overconfidence
- Symptoms: A “Lake Wobegon effect,” overconfidence creates a statistical impossibility: Everyone thinks they’re above average.
- Damage Done: Overconfidence puffs up your belief that you’ve got the rare luck or skill required to consistently “beat” the market, instead of patiently participating in its long-term returns.
The Bias: Pattern Recognition
- Symptoms: Looks can deceive. Our survival instincts strongly bias us toward finding predictive patterns, even in a random series.
- Damage Done: By being predisposed to mistake random market runs as reliable patterns, investors are often left chasing expensive mirages.
The Bias: Recency
- Symptoms: Out of sight, out of mind. We tend to let recent events most heavily influence us, even for our long-range planning.
- Damage Done: If you chase or flee the market’s most recent returns, you’ll end up piling into high-priced hot holdings and selling low during the downturns.
The Bias: Sunk Cost Fallacy
- Symptoms: Throwing good money after bad. It’s harder to lose something if you’ve already invested time, energy or money into it.
- Damage Done: Sunk cost fallacy can stop you from selling a holding at a loss, even when it is otherwise the right thing to do for your total portfolio.
The Bias: Tracking Error Regret
- Symptoms: Shoulda, coulda, woulda. Tracking error regret happens when you compare yourself to external standards and wish you were more like them.
- Damage Done: It can be deeply damaging to your investment returns if you compare your own performance against apples-to-oranges measures, and then trade in reaction to the mismatched numbers.
Even once you’re familiar with the behavioral biases that stand between you and clear-heading thinking, you’ll probably still be routinely tempted to react to the fear, greed, doubt, recklessness and similar hot emotions they generate. This is one reason an objective advisor can be such a critical ally, helping you move past your reactionary thinking into more deliberate decision-making for your long-term goals.
If you could use some help managing the behavioral biases that are likely lurking in your blind spot, give us a call. In combating that which you cannot see, two views are better than one.
Cold Calls, Golf Balls and Ongoing Gratitude
Even though Thanksgiving is over (except for a few leftovers) I hope to keep being thankful for life’s many ongoing twists and turns. That’s why I keep a golf ball in my overcoat throughout the year. It may look like just an ordinary object, but it’s special to me, because it reminds me of how grateful I am to be part of Hill Investment Group.
Similar to the experiences Matt Hall shared in Odds On, I too started my financial career in a sales-oriented culture. We’ll call my first gig “Big Broker,” where we were taught how to sell financial wares via cold-calls and door-to-door canvassing. The bulk of our so-called education was on how to overcome any objections, instead of on what it takes to be a worthy advisor.
In other words, just about everything I learned at Big Broker was exactly the opposite of the Hill Investment Group culture, where we strive to center everything we do around our clients’ highest financial interests.
So, what’s that golf ball got to do with it? Back in my Big Broker days, we were shown how to use it to save our knuckles during our sales outings. If you’ve ever knocked on a lot of doors in all kinds of weather, you learn quickly how much that can hurt. On the good days, I’d end up knocking a couple hundred times, delivering my canned speech dozens of times, and generating one or two good leads. On some of my worse days, I was bitten by dogs, pooped on by birds and stung by bees.
Maybe I deserved it for pestering people in their homes, whether or not they wanted an uninvited guest.
As you might imagine, whenever I stopped to think about it (which started happening with increasing frequency!), I thought, “There’s got to be a better way to help people invest their hard-earned assets.”
Thankfully, I discovered that better way when I came across HIG in 2012. Reading through the materials they shared with me, I was immediately hooked … to the point where I was late for a dinner outing because I had to finish reading about this amazing “new” perspective. It was new to me, anyway. Then I was up early the following Saturday to read some more. I call this my “Light Bulb Moment,” which we shared in this 2015 video:
John Reagan: His Light Bulb Moment from Hill Investment Group.
Unfortunately, the Michael Lewis piece I reference in this video is out of print and no longer available. But there are plenty of other great resources published since then to take its place. Let us know if you could use some assistance in generating your own light bulb moment. I’d be happy to help, and grateful to share what else I’ve learned after I got to tuck my cold-call golf ball away for good.
Who’s in Your Corner?
At Hill Investment Group, we love to ask questions – to get to know you upon initial meeting and discover more about you as we go. But what questions should investors be asking? Here are “The 19 Questions to Ask Your Financial Advisor” (or a prospective advisor) according to Jason Zweig of The Wall Street Journal. At the highest level, these 19 questions seek to establish the rhetorical question: Are you paying your advisor to serve YOUR best interests or their own?
“The obligation of those who give investment advice to serve clients, not themselves, is called fiduciary duty. That obligation is far from universal and, in some ways, is in retreat,” says Zweig (emphasis ours).
The challenge, however, is merely asking an advisor if they are a fiduciary may not suffice. Zweig’s queries will help you differentiate fake fiduciary “talk” from a real fiduciary “walk.”
Zweig also provides the answers he feels are most appropriate, while leaving #12 (“What is your investment philosophy?”) curiously blank. We agree wholeheartedly with nearly all of his suggested responses, although there are a couple we would qualify. And of course we have quite a lot to say about that curiously blank one. Here, we’ll simply add the words of Dimensional Fund Advisors’ co-founder Rex Sinquefield, as he describes evidence-based investing: “This investment approach is easy to communicate, is verifiable, and is eminently defensible.”
This and many other great insights are found in Dimensional’s recently published “35 Quotations on a Better Way to Invest.” Want a copy of it, or would you like to know where else we differ on Zweig’s other questions (and why)? Just ask!
Oh, by the way, YES, we are a fiduciary firm – in name and practice.
