Behavioral Biases: Symptoms and the Financial Damage Done

Behavioral biases can inhibit your ability to Take the Long View.®

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.

If Anyone Could Beat the Market …

Pursuing an evidence-based approach to investing (as we do) includes hearing from those whose thoughts align with ours as well as those who challenge our assumptions. In that spirit, one of my recent reads was “A Man for All Markets: From Las Vegas to Wall Street, How I Beat the Dealer and the Market,” by Edward Thorp.

That’s a big book title, from a larger-than-life author. Even if he spiced up his story with a few potential exaggerations, Thorp obviously is one of the most brilliant people you may never have heard of.

A childhood genius and young math professor turned Vegas gambler turned hedge fund manager, Thorp knew his way around the data analysis block, warning a client about Bernie Madoff’s fake trades before the news went public.

He also suggests he scooped Nobel laureate Myron Scholes and collaborator Fischer Black on their insights into how to price options and other financial risks. The implication is that Nobel prize would have been his, had he played his cards right. He doesn’t say how much he earned over his career, but in the the book, he states that Citadel Investment Group was built using his market-neutral strategy, and the managing partner was worth $5.6 billion at last count.

Then there were his casino-beating tactics – employing statistical analysis to tilt the odds in his favor, plus a few tricks up his sleeves to stay in the game (such as wearing disguises once the casinos were onto him). I found this portion of the book the most entertaining.

But what about his investment advice? If anyone could crack the code on how to consistently beat the market, you’d think it would be Edward Thorp. Instead, when he tried his hand at active stock-picking, he soon discovered the same thing we did: Stock-picking advice is worthless, after-the-fact news.

The conclusions Thorp drew from there differ from our own. One of his chapter titles says it all: “Wall Street: The Greatest Casino on Earth.” While Thorp tries to apply some of his casino-beating tactics to pursue statistically significant edges over the market, we feel there’s more compelling evidence suggesting long-term investors are better served with a less dicey approach.

A Man for All Markets” is a fun summer read for peeking inside the mind of a mathematical whiz with a flair for living and investing on the edge. When it comes to managing your money for all markets, we continue to recommend evidence-based investing.

Eugene Fama Awarded Nobel Prize in Economic Sciences

We are thrilled to share the news that, this week, Eugene Fama, the “father of modern finance,” was awarded the Nobel Prize in Economic Sciences. Professor Fama was honored along with fellow professors Lars Peter Hansen and Robert Shiller for their “empirical analysis of asset prices.” Among America’s most prolific and cited researchers, he focuses much of his study on market prices.

It is rewarding to see such a high level of recognition given to Professor Fama. His contributions have served as a bedrock for our investment philosophy and have shaped how we help our clients achieve their most important goals. All of us at Hill Investment Group congratulate Professor Fama on this great honor.
