Understanding Behavioral Finance Paradoxes

 “THE INVESTOR’S CHIEF problem—even his worst enemy—is likely to be himself.” So wrote Benjamin Graham, the father of modern investment analysis.

With these words, written in 1949, Graham acknowledged the reality that investors are human. Though he had written an 800 page book on techniques to analyze stocks and bonds, Graham understood that investing is as much about human psychology as it is about numerical analysis.

In the decades since Graham’s passing, an entire field has emerged at the intersection of psychology and finance. Known as behavioral finance, its pioneers include Daniel Kahneman, Amos Tversky and Richard Thaler. Together, they and their peers have identified countless human foibles that interfere with our ability to make good financial decisions. These include hindsight bias, recency bias and overconfidence, among others. On my bookshelf, I have at least as many volumes on behavioral finance as I do on pure financial analysis, so I certainly put stock in these ideas.

At the same time, I think we’re being too hard on ourselves when we lay all of these biases at our feet. We shouldn’t conclude that we’re deficient because we’re so susceptible to biases. Rather, the problem is that finance isn’t a scientific field like math or physics. At best, it’s like chaos theory. Yes, there is some underlying logic, but it’s usually so hard to observe and understand that it might as well be random. The world of personal finance is bedeviled by paradoxes, so no individual—no matter how rational—can always make optimal decisions.

As we plan for our financial future, I think it’s helpful to be cognizant of these paradoxes. While there’s nothing we can do to control or change them, there is great value in being aware of them, so we can approach them with the right tools and the right mindset.

Here are just seven of the paradoxes that can bedevil financial decision-making:

  1. There’s the paradox that all of the greatest fortunes—Carnegie, Rockefeller, Buffett, Gates—have been made by owning just one stock. And yet the best advice for individual investors is to do the opposite: to own broadly diversified index funds.
  2. There’s the paradox that the stock market may appear overvalued and yet it could become even more overvalued before it eventually declines. And when it does decline, it may be to a level that is even higher than where it is today.
  3. There’s the paradox that we make plans based on our understanding of the rules—and yet Congress can change the rules on us at any time, as it did just last year.
  4. There’s the paradox that we base our plans on historical averages—average stock market returns, average interest rates, average inflation rates and so on—and yet we only lead one life, so none of us will experience the average.
  5. There’s the paradox that we continue to be attracted to the prestige of high-cost colleges, even though a rational analysis that looks at return on investment tells us that lower-cost state schools are usually the better bet.
  6. There’s the paradox that early retirement seems so appealing—and has even turned into a movement—and yet the reality of early retirement suggests that we might be better off staying at our desks.
  7. There’s the paradox that retirees’ worst fear is outliving their money and yet few choose the financial product that is purpose-built to solve that problem: the single-premium immediate annuity.

How should you respond to these paradoxes? As you plan for your financial future, embrace the concept of “loosely held views.”

In other words, make financial plans, but continuously update your views, question your assumptions and rethink your priorities.

‘There are people with high I.Q.s who have fooled themselves on that one,’ Bill Gates the billionaire Microsoft co-founder told The New York Times. Gates’ comments come as Bitcoin has hit record highs in recent weeks, and the cryptocurrency industry as a whole has hailed the arrival of Donald Trump in the White House as a positive moment. 

The President has said he will introduce policies supportive of digital currencies, and both him and his wife Melania launched their own meme coins last month. Cryptocurrency prices took a hit on Monday from the prospect of a trade war between the US and its trading partners, with some well-known digital assets seeing values fall more than 10 percent, AP News reported. However the notoriously volatile investment recovered later on Monday, with Bitcoin rebounding back above $100,000. Gates, who has a net worth of around $165 billion, has previously shared his skepticism around Bitcoin, and its volatility in particular.

US stocks closed higher on Tuesday, led by Big Tech, as investors assessed China’s instant retaliation to US President Donald Trump’s additional tariffs and the potential risks of a trade war.

Traders also took in fresh jobs data, with job openings declining more than expected in December. Investors are continuing to watch any signs of cooling in the labor market as the Federal Reserve debates future interest rate cuts in the face of sticky inflation.

The Dow Jones Industrial Average (^DJI) gained around 0.3%, while the benchmark S&P 500 (^GSPC) rose roughly 0.7%. The tech-heavy NASDAQ Composite (^IXIC) jumped nearly 1.4% to recoup some of Monday’s losses.

Beijing reacted swiftly on Tuesday to Trump’s additional 10% levies on Chinese imports going into effect at midnight. China slapped tariffs of 15% on US coal and liquified natural gas, starting Feb. 10, alongside 10% duties on imports of crude oil, farm equipment, and some autos.
