LIKE THE COBBLER whose children have no shoes, I get so busy with this website and other projects that I tend to neglect my own portfolio. I think of it as benign neglect: If you’re invested in a globally diversified portfolio of low-cost index funds, there isn’t much reason to look or much need to trade.
But for the past week or so, I’ve been doing plenty of looking—and a little trading.
By the market close on Dec.

HOW THINGS LOOK depend on where you stand. Trying to figure out how to respond to the market drop? After the initial slump, a brief rally and then another decline, the S&P 500 is down 10% from its September all-time closing high of 2930.75.
History suggests that, five years from now, share prices will be no lower than they are today, and 10 years from now they’ll be handsomely higher. But at times like this,

ALLAN ROTH LIKES to describe himself as argumentative—and, on that score, it’s hard to argue with him. But it’s also hard to argue with the points he makes, because he has this nasty habit of being right.
Roth is the author of How a Second Grader Beats Wall Street, a financial planner who charges by the hour, and a contributor of financial articles to AARP.org, Financial-Planning.com, NextAvenue.org and other sites. I caught up with him last month at the Bogleheads’ conference in Philadelphia.

RECENT MARKET turbulence, including today’s sharp stock market drop, has been a wakeup call for many investors. Feeling queasy? It isn’t too late to make portfolio changes: The S&P 500 may be down 9% from its all-time high, but it’s still up an eye-popping 293% since March 2009.
Here are three quick calculations that might spur you to action—or help ease your mind:
1. How much cash do you need from your portfolio over the next five years?

IN THE MID-1990s, Federal Express had a problem. Though the company’s safety record was exemplary, regulators had proposed new rules that would have posed an operational nightmare for the giant shipper.
The company flew Boeing 727 air freighters that each accommodated eight containers. Though they had never had a problem, the government’s concern was that if two heavier-than-average containers were loaded next to each other, it could cause the plane to become dangerously unbalanced.

I DON’T WANT BONDS in my portfolio—or, at least, not to the degree traditionally recommended in financial planning guidelines.
For years, I had accepted the premise that bonds should be included in a serious investor’s portfolio. Not that I necessarily followed that dictum. But I accepted the idea that young people should have a low percentage in bonds, and increasingly greater percentages through middle age and retirement.
I kept thinking that someday I’d come around to more bonds,

AS YOU NO DOUBT noticed, the stock market took investors on a wild ride last week. On Wednesday, the Dow industrials dropped more than 800 points. On Thursday, the Dow lost another 546 points. Friday was better, up 287 points, but there was still plenty of stomach-churning volatility.
At times like this, I’m reminded of Warren Buffett’s motto: “You want to be greedy when others are fearful, and you want to be fearful when others are greedy.” While that certainly sounds logical,

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.

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.
