ON WEDNESDAY, Vanguard Group’s 89-year-old founder John C. Bogle was in hospital to receive treatment for his latest health scare—an irregular rhythm in his transplanted heart. On Thursday and again today, he was at the Bogleheads’ 17th conference in Philadelphia, as feisty as ever.
The Bogleheads are, of course, the online community who congregate at Bogleheads.org. They’re renowned as fans of frugality—especially frugally priced index funds. And Jack Bogle—even though it’s been more than two decades since he was Vanguard’s Chief Executive Officer—remains their guiding light.

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.

I AM NOT AN investment expert. I am befuddled by such things as puts and calls. Who is putting what where?
I do know the difference between stocks and bonds. I know that bond prices go up when interest rates go down, and vice versa, and I eventually figured out why. I also know stock markets are used to raise capital and that shareholders are actually owners of a company, but with little power or influence,

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.

WHEN I WAS a columnist at The Wall Street Journal, I repeatedly heard two complaints from editors, especially those with little understanding of personal finance: “Our readers want something more sophisticated” and “Where’s the news hook?”
That, in a nutshell, explains why the media can be so bad for our financial health. When print and broadcast journalists cave in to the twin imperatives of timeliness and sophistication, they’re almost guaranteed to lead their audience astray—for three reasons:
1.

WE CAN’T CONTROL the financial markets. But we can pretty much guarantee we’ll pocket whatever the stock and bond markets deliver—by buying index funds. So why do I hear so much grousing from indexers?
At issue isn’t a failure of index funds, but rather a failure of investors’ expectations. Over the past few months, I’ve heard from countless hardcore indexers who have done the sensible thing and built globally diversified portfolios. Often, they own some variation of the classic three-fund portfolio: a total U.S.

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,

WE HAVE FINALLY HIT rock-bottom. Last week, Fidelity Investments announced that it was introducing two index funds with zero annual expenses, while also slashing expenses on its other index funds and dropping the required minimum investment on all funds, both actively managed and indexed. All of this raises five key questions.
1. Why is Fidelity doing this? I view Fidelity’s move as both bold and borne of desperation. When I started writing about mutual funds in the late 1980s,

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?

I’M STILL WAITING. Along with many others, I have spent much of my investing career expecting five key financial trends to play themselves out—and yet they’ve stubbornly refused to do so.
Sure, these predictions could still come true. But I have my doubts. Maybe these five financial forecasts aren’t the slam dunk they appear:
1. Stocks will revert to average historical valuations. Whether you look at price-earnings ratios, cyclically adjusted price-earnings ratios,

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.
