MY GRANDFATHER WAS from Queens in New York City. He was a great guy and taught me a lot. He was also a native New Yorker, so he was street smart and tough.
One day, while we were walking together down 47th Street, near Times Square, I stopped to look at the jam-packed window of an electronics store. My grandfather waited patiently, but cautioned me, “Careful, they’ll take the eyes out of your head.”
It was a funny expression,

ALBERT EINSTEIN reportedly once said, “Everything should be made as simple as possible, but not simpler,” or words to that effect.
When it comes to investing, I have always believed that the simplest approach is the best approach. But in recent years, a new type of investment has, I believe, crossed over into the “too simple” category.
This new type of investment: target-date mutual funds. If you aren’t familiar with them, target-date funds are mutual funds that typically buy other funds.

THE NOTED PHYSICIST Lord Kelvin reportedly declared in 1900, “There is nothing new to be discovered in physics now.” In the annals of inaccurate proclamations, this one stands out. Just a few years later, Einstein published his Theory of Relativity and, in the following years, proceeded to upend many of the scientific world’s longest standing and most deeply held beliefs.
The world of personal finance witnessed a similarly inaccurate prediction 76 years later. When the newly formed Vanguard Group launched its first index fund,

THE STOCK MARKET recently hit yet another all-time high. But instead of unalloyed glee, many investors are struggling with mixed emotions. They’re thrilled at their gains. But at the same time, they’re hesitant to put more money into a market that has already gained so much.
Result: Folks have been asking, “Isn’t there anything else I can buy?” Often, this leads to questions about alternative investments. Below is an introduction to the topic,

KANYE WEST, IT TURNS out, is one heck of an investor. According to a recent analysis, a group of West’s stock picks has beaten the overall market by 40 percentage points this year. It’s an astonishing result. What, if anything, can we learn from his performance?
First, some background: As you may know, West is married to Kim Kardashian, who is one of the dominant personalities on social media, so it was via Instagram that the world gained a window into these investments.

MY SONS’ BASKETBALL coach, George, has a favorite expression: He talks about “working through the uglies.” When you’re developing a new skill, he says, you shouldn’t expect to be perfect the first time or even the second. But if you keep working at it, over time there will be progress, “from ugly to not-so-bad to decent to good and then, eventually, to great.” The message is clear: You can’t rush it, you can’t skip steps and you have to start with the basics.

A CURIOUS THING happened in Stockholm in 2013. The Royal Swedish Academy of Sciences awarded the Nobel Prize in economics to three academics who had developed theories about stock prices. What was odd was that two of the recipients—Eugene Fama and Robert Shiller—couldn’t have been more opposed in their viewpoints.
Fama believes that stock prices are always rational and that there’s no such thing as a market bubble. Shiller believes that stock prices are often irrational and that bubbles do occur.

IF YOU’RE A FAN of basketball, you may be familiar with the Lopez twins—Brook and Robin. On the surface, they are identical in every way. Both stand seven feet tall. Both went to Stanford University. Both entered the NBA draft in 2008 and both were picked in the first round. Since then, both have enjoyed successful careers.
A casual observer would be hard-pressed to see any difference between the Lopez twins, but there is one: While they are both impressive players,

THE SELF-PROCLAIMED fortune-teller Nostradamus published more than 6,000 predictions during his lifetime. With the benefit of hindsight, it’s easy to see that his prophecies had little substance or predictive value. In fact, in his day, even astrologers dismissed Nostradamus as incompetent.
But what if the person making a prediction is the opposite of Nostradamus? What if he is a serious individual, someone who is universally respected and whose forecasts have a demonstrated track record of success?

IN THE FIELD OF epidemiology, researchers have long used the term “tipping point” to describe how epidemics occur. At first, an ordinary disease moves slowly, not gaining much attention. But then, seemingly overnight, it snowballs into something far larger.
Within the world of public health, this concept is well understood. But about 20 years ago, the author Malcolm Gladwell took a closer look and pointed out that tipping points can be found in a whole host of other situations far beyond epidemiology.

A QUESTION FOR YOU—a trick one, I admit: Should you invest in technology stocks, such as Apple?
My answer: Yes, certainly.
Another question, also a trick one: Should you invest in the stocks of entertainment companies like Netflix?
My answer: Again, yes, of course.
A third question: Should you invest in energy companies, such as ExxonMobil?
My answer: Again, yes.
You might wonder why I’m asking these questions and why I’m answering “yes” to all of them.

NOT LONG AGO, I RAN into my friend Martin, who works as a cardiologist at a local hospital. In the course of our conversation, I commented on the construction equipment outside his facility and asked what they were building.
His answer: “Building? No, they’re actually un-building.”
He explained that recently his hospital had been sold and the new owner was a for-profit company. As part of the transition, the new owner had evaluated the hospital’s facilities and discovered that a group of older buildings was largely unused.

WHEN YOU WERE growing up, did you ever hear stories like these?

“If you swallow gum, it will stay in your stomach for seven years.”
“If you keep making that face, it will freeze that way.”
“If you drink coffee, it will stunt your growth.”
“If you watch too much TV, your eyes will turn square.”

In hindsight, these stories are funny and harmless. But problems can arise if, as adults, we make important decisions based on misinformation.

IN THE SUMMER of 1789, George Washington got into a dispute with his Postmaster General—a fellow named Ebenezer Hazard—and removed him from office.
Looking for a new profession, Hazard decided to start an insurance company. He called his new firm the Insurance Company of North America and specialized in providing life insurance to ship captains. The business was a perfect fit for the times and quickly prospered. Still, I’m sure that even Hazard would be surprised to see his company still in business more than two centuries later.

“THERE ARE TWO kinds of people in the world…” There are Republicans and Democrats. Right-brained and left-brained. Yankees fans and Red Sox fans. And, of course, Starbucks people and Dunkin’ Donuts people.
In Boston, where Dunkin’ was founded and where I live, this is a particularly strong theme. Dunkin’ people and Starbucks people see themselves as very different. Starbucks aficionados see it as a higher-quality experience and don’t mind paying for it. Meanwhile, Dunkin’ fans are proud of their frugality and think that the people over at Starbucks are overpaying.
