IN 1774, AMSTERDAM businessman Abraham van Ketwich created a new type of investment. After raising money from a group of individuals, van Ketwich built a portfolio of bonds. He deposited the bonds in a metal box in his office, which three people then secured using three different locks.
Van Ketwich’s fund could be considered the world’s first index fund. How so? For starters, the bonds purchased were broadly diversified across industries and geography. Second,

IN THE ANCIENT WORLD, before the invention of the printing press, a strategy for remembering information was to build a so-called memory palace. The idea was to associate words with images. Even today, this is how participants in memory competitions can achieve feats like reciting a thousand digits of pi.
Similarly, when it comes to personal finance, I’ve found that certain images can help illustrate important concepts. These are the ones I rely on the most:

IN THE 1990s, Mark Cuban started one of the first internet companies, a video streaming service called Broadcast.com, and later sold it to Yahoo for several billion dollars. With some of the proceeds, he bought the Dallas Mavericks NBA franchise and sold that as well, taking home another several billion dollars.
And for 16 seasons, Cuban appeared on the reality TV show Shark Tank, in which entrepreneurs present ideas to a panel of prospective investors.

NINE MONTHS AGO, Jonathan Clements shared with readers that he’d been diagnosed with an incurable form of cancer. It was devastating news, especially for longtime readers, many of whom regard Jonathan not only as a journalist but also a friend. I count myself among them, so I was grateful that Jonathan agreed to sit for an interview to share more about his background, his early years and his current thinking. 
You’ve joked that,

THE U.S. STOCK MARKET has historically delivered similar returns under both Democrat and Republican administrations. For that reason, my view is that investors shouldn’t worry too much about who occupies the White House, and I tend to stay away from investment discussions that involve politics.
But sometimes, the news coming out of Washington dominates the headlines in a way that can’t be ignored. Such is the case today. Moreover, with the stock market faltering recently,

THIS MONTH MARKS the five-year anniversary of the start of the pandemic. That makes this a good time to look back and ask what lessons we might learn.
In early 2020, when COVID-19 was first identified in the U.S., the stock market dropped 34% in the space of just five weeks. But later in the year—after the Federal Reserve stepped in with its bazooka—the market rebounded, ending the year in positive territory. For full-year 2020,

THERE’S A CHANGE coming in the way many of us invest. But for background, it’s important first to look at a related—though seemingly mundane—investment concept known as tax-loss harvesting.
To understand how tax-loss harvesting works, consider a simple example. Suppose you purchased a stock in your taxable account for $10, and it subsequently dropped to $8. That would be unfortunate, but there’d be a silver lining: You could sell the stock to capture the $2 loss for tax purposes and then reinvest the proceeds in another stock.

FIFTY YEARS AGO, when the first index funds were getting started, critics wasted no time attacking the idea. They called it “un-American” and a “sure path to mediocrity.”
But over time, indexing has grown to the point where it now accounts for more than half of all U.S. mutual fund assets. Last year, research firm Morningstar declared that “index funds have officially won.” But this victory seems to have only increased the level of criticism.

MARVIN STEINBERG was a psychologist who founded the Connecticut Council on Problem Gambling. During his career, he made some uncomfortable observations about the behavior of stock market investors. In many cases, he felt, investors’ behavior veered awfully close to gambling.
This is the sort of observation that seems like it could be true, but it also seems difficult to quantify. That’s why a recent study by Morningstar analyst Jeffrey Ptak caught my eye.
Ptak wanted to examine investors’ experience with so-called thematic funds.

IN WASHINGTON, 2025 is beginning to look a lot like 2017. Republicans again control the White House, the Senate and the House of Representatives. But a key difference between then and now is that today the Republican majority in the House is far narrower.
This means more negotiation will be required, and agreement on a new tax bill may take months. In the meantime, here are some key areas that investors will want to keep an eye on.

A QUOTE OFTEN attributed to Mark Twain goes as follows: “It ain’t what you don’t know that gets you into trouble. It’s what you know for sure that just ain’t so.”
This certainly applies to personal finance, and it’s why it can be helpful to take a step back sometimes to revisit widely held notions—including these six.
1. Social Security. You may have heard of Social Security’s “earnings test,” which can reduce the size of monthly checks for those who continue working after claiming benefits.

MICHAEL BURRY IS a hedge fund manager who gained fame betting against the housing market in 2008. When that market collapsed, Burry made a fortune, and that cemented his reputation as a market seer. Burry was later portrayed as the central character in Michael Lewis’s The Big Short.
But in the years since, Burry’s predictions haven’t turned out as well. Five years ago, he spooked index-fund investors when he argued that they might have trouble accessing their funds.

ONE SPRING DAY IN 2022, an elderly woman entered Paris’s Picasso Museum to see a new exhibit. Among the items on display was a decorative blue jacket, which was positioned on a wall next to a portrait of Picasso.
The woman liked the look of the jacket, so she took it down from its hook, put it in her bag and quietly walked out the front door. Only later did the museum discover the theft,

IN THE FINANCIAL world, some topics are serious, others not so much. Since it’s the holiday season, it seems appropriate to look back at some of the past year’s lighter moments.
No joke. In 2019, artist Maurizio Cattelan unveiled a collection he called Comedian. The item that received the most attention: a sculpture that consisted only of a banana duct-taped to a wall. The banana gained fame when it sold at a Miami auction for $120,000.

EARLY LAST WEEK, The Wall Street Journal ran an article with the headline “Why This Frothy Market Has Me Scared.” The author cited a number of indicators that have him worried, including a survey of investor optimism that’s at a 35-year high. Investors, the Journal said, are feeling “euphoric,” and that’s often a bad sign.
So, as we head into year-end, it’s worth taking stock of where things stand. The stock market has returned nearly 25% so far this year.
