Investor who manages $900 million in assets says there’s one investing hack everyone should know: ‘I wish they would teach it more in high school’

Published

on



Mohnish Pabrai, a prominent value investor who manages approximately $900 million in assets through his Pabrai Investment Funds, has identified a simple mathematical concept he believes should be fundamental education for every investor: the Rule of 72.

During a recent appearance on The Diary of a CEO, a popular business podcast hosted by British entrepreneur Steven Bartlett, Pabrai emphasized the importance of this financial principle. The Rule of 72 is a simple way to help you calculate how long it takes money to double at a given interest rate.

“It’s a kind of a mathematical hack,” Pabrai said during the interview. “The rule of 72 is a very important rule, and I wish they would teach it more in high schools and elementary school.”

The formula works by dividing 72 by the expected annual return percentage. For example, at a 7% return, money doubles in approximately 10 years (72 ÷ 7 = 10.3). At 10% returns, doubling occurs in roughly seven years, while 15% returns cut the doubling time to about five years.

“It’s very important to know how long money takes to double, because then we can start doing a lot of math in our heads,” Pabrai said.

This mental calculation ability allows investors to quickly assess the long-term potential of different investment opportunities without complex financial calculators.

The power of compound interest

To illustrate the power of compound interest, Pabrai shared a compelling historical example during the interview. In 1623, Native American Indians sold Manhattan to Dutch settlers for $23. Yes, you read that right.

“If the Indians had invested at 7% a year for the last 400 years, they would have more money than owning the land,” he explained. Using the Rule of 72, that $23 would have doubled every 10.3 years at 7% returns. Over 400 years, this would have resulted in approximately $23 trillion—significantly more than the value of Manhattan real estate today, which is estimated to be in the ballpark of $2.2 trillion.

The example becomes even more striking when scaled down: “If you gave them 2.3 cents, 100 years later, they’d have $23, and now it would be the 23 trillion,” Pabrai noted, adding “if the runway is long enough, the starting capital doesn’t matter.”

Beyond the mathematical concept, Pabrai offered practical advice for everyday investors during the interview. He emphasized three fundamental principles: “spend less than you earn,” start investing young to maximize the compounding runway, and focus on broad market indices rather than individual stock picking.

“You could open an account at Fidelity or Interactive Brokers or Robin Hood, any of these places,” he said. “You could just ask them to give to buy you the S&P 500 index, for example, and they will get you invested in that.”

Pabrai said if you start investing at age 18, an initial $5,000 investment with a 10% return would result in approximately $500,000 by age 68, thanks to the money doubling seven times over the 50-year period.

“You can start seeing that over a lifetime, you’re going to be having too much money,” he noted.

The investment guru

Pabrai’s advocacy for this simple mathematical tool demonstrates how foundational financial concepts, when properly understood and applied, can transform investment outcomes. His message is clear: The path to wealth isn’t through complex strategies or market timing, but through understanding the fundamental mathematics of compound growth and having the patience to let it work over time. Plus, the simplicity of the rule—valuable for quick mental calculations—helps investors appreciate why maintaining consistent returns matters more than chasing spectacular short-term gains.

Pabrai brings considerable credibility to his investment recommendations. Born in Mumbai in 1964, he moved to the United States to attend Clemson University before launching his entrepreneurial career. After founding and successfully selling his IT consulting company TransTech for $20 million in 2000, Pabrai transitioned into investing, launching his investment funds in 1999.

Pabrai has built an impressive track record over more than two decades. His funds achieved cumulative returns of 517% net to investors versus 43% for the S&P 500 from 2000 to 2013, representing outperformance of 474 percentage points. Since inception, his funds have delivered annualized returns of approximately 25%, though recent years have shown more mixed performance relative to benchmarks.

Pabrai’s investment philosophy closely mirrors that of Warren Buffett, whom he famously paid $650,100 to have lunch with in 2007 alongside fellow investor Guy Spier.

Activist investors are targeting female CEOs—and it’s costing Corporate America

Published

on



Good morning. When Victoria’s Secret reported stellar quarterly results last week, shares shot up 14% and likely gave Hillary Super some breathing room from the activist investors pushing the lingerie company to, among other things, consider whether the CEO of 16 months is up to the task of turning it around.

Of course, the potential of having to deal with an activist investor’s campaign goes with the territory of being a CEO, especially at a company that has been struggling. But Super’s saga is a reminder that women CEOs remain much likelier than their male counterparts to be targeted by activist investors.

This year, according to a report last week by the Conference Board, women have made up 8% of the CEOs in the Russell 3000 index but accounted for 15% of activist campaigns specifically targeting chief executives. Other women to have recently confronted activists: Cracker Barrel’s Julie Masino, who survived a campaign, and Vail Resorts’ Kirsten Lynch, who did not. 

What makes the Conference Board report especially frustrating is that it adds more proof points to an old, seemingly intractable trend.

In 2015, the New York Times’ DealBook pondered “Do Activist Investors Target Female CEOs?” while Fortune’s Pattie Sellers asked “Does Nelson Peltz have a problem with women?” In 2017, Harvard Law School found that women CEOs had almost a 50% higher probability than men of becoming the target of shareholder activism.

Why? One reason, the Conference Board theorized, is rooted in a stereotype that women are more cooperative. It’s also conceivable that the trend reflects the glass cliff phenomenon in which women often take the helm of companies in decline. But there is almost certainly some bias at play. The Conference Board research showed that women targeted by activists face the same odds of being canned whether they turn things around or not, while male CEOs are less likely to be ousted when results improve.

Some of the most prominent women chief executives ever have tangled with activists: PepsiCo’s ex-CEO Indra Nooyi, ex-Yahoo CEO Marissa Mayer, ex-DuPont CEO Ellen Kullman, ex-Mondelez CEO Irene Rosenfeld, ex-HP CEO Meg Whitman, and Mary Barra, still at GM. Michelle Gass, now thriving as CEO of Levi Strauss & Co, dealt with not one but three activist campaigns as she tried to fix Kohl’s.

Everyone should be held accountable when their company is failing or on a bad path. But it is worth wondering what this extra hurdle women CEOs face is costing us. Activist campaigns are bruising to the company but also to a CEO’s reputation. Does this mean boards might be more likely to avoid naming a woman to lower the odds of an activist campaign, or that fewer women will throw their hat in the ring?

Either way, it seems the phenomenon could needlessly be costing corporate America some much needed talent.—Phil Wahba

Top news

Fed watch

All eyes will be on the Fed meeting today even though an interest rate cut is all but certain. Instead, investors will focus on Chair Jerome Powell’s tone and whether he characterizes Fed policy as “in a good place;” doing so would imply that a January cut is unlikely. 

Fed chair watch 

Meanwhile, President Donald Trump has narrowed down the candidates to replace Powell as Fed chair. The frontrunner is National Economic Council Director Kevin Hassett, but to clinch the job he’ll reportedly have to outshine three other contenders in the final round of interviews, suggesting he’s not a shoo-in for the job. 

Trump’s affordability tour

In his first in a series of speeches about “affordability,” President Trump mocked the term and insisted that Americans are doing better than ever. In reality, U.S. inflation is close to 3%, about where it was when Trump’s predecessor Joe Biden left office. 

Miami’s mayoral race

As Trump railed against affordability, Eileen Higgins, a Democrat, defeated Trump’s favored candidate in Miami’s mayoral race with a campaign focused in part on affordable housing. She’s the first Democrat to occupy Miami’s City Hall in three decades (and the first-ever woman), giving Democrats another jolt of momentum ahead of the 2026 midterms. 

Taiwan’s chip action

Taiwan is invoking a national security law to protect the trade secrets of its homegrown chipmaker TSMC and has used it to indict a TSMC supplier for allegedly letting a former employee steal details about TSMC’s top chips. 

Layoffs hit 1.1 million

Recruitment firm Challenger, Gray & Christmas has calculated the number of layoffs so far this year at 1.1 million, the sixth time since 1993 that layoffs have been that high. Technology was the hardest hit sector with 150,000 layoffs.

Americans ‘living on the financial edge’

Moody’s Analytics Chief Economist Mark Zandi told Fortunethat many Americans are “already living on the financial edge,” and that a drop in their spending could lead to a recession. If layoffs increase, then Zandi estimates that a “jobs recession” is certain. 

Sam Altman worries about ‘rate of change’

During an appearance on The Tonight Show with Jimmy Fallon, OpenAI CEO Sam Altman admitted that he’s worried about “the rate of change that’s happening in the world right now.” He added that the “rate at which jobs will change over may be pretty fast,” with hopes that “much better jobs” will follow. 

The markets

S&P 500 futures were up 0.05% this morning. The last session closed down 0.09%. STOXX Europe 600 was down 0.19% in early trading. The U.K.’s FTSE 100 was up 0.14% in early trading. Japan’s Nikkei 225 was down 0.1%. China’s CSI 300 was down 0.14%. The South Korea KOSPI was down 0.21%. India’s NIFTY 50 is down 0.32%. Bitcoin is up at $93K.

5 VCs sounds off on the AI question du jour

Published

on



The views seem to range from bubble-wary to bubble-dismissive. We hashed it all out over eggs and sausages at Fortune’s IRL Term Sheet Breakfast at Brainstorm AI in San Francisco yesterday. This is Amanda Gerut, Fortune’s West Coast news editor, pinch-hitting for my colleague Allie Garfinkle.

Allie hosted five VCs with funds ranging in size from $5 million to $25 billion and views varied across the panel. This group alone is collectively going to deploy anywhere from tens to hundreds of millions over the next decade into companies with AI as a backdrop and these investments will either prove spectacularly right or wrong.

Here’s a roll call:

Jenny Xiao, partner at Leonsis Capital and former researcher at OpenAI, came in with a nuanced take. There’s something of a bubble, but it’s “relatively contained” in the infrastructure layer with overinvestment primarily in data centers, GPUs and in large language model companies. But right now, there’s actually underinvestment in the application layer because there are so many ways AI can make an impact in various enterprises, Xiao said. 

Vanessa Larco, former partner at New Enterprise Associates (NEA) and co-founder of new venture firm Premise, has a contrarian view. “Everyone thinks enterprise is safer,” Larco said. “But I actually think the consumer might, this time around in the current environment, be what survives.” Larco’s reasoning is that if a consumer adopts your AI product, it’s because you’re giving them something faster, “radically cheaper, or much easier to use.” Once you’ve done that and built a brand, it’s very hard for people to quit you. 

Rob Biederman, managing partner at Asymmetric Capital Partners and chairman of Catalant Technologies, had a sobering view. “In every boom, 99% or 99.9% of companies fail, and one or two of them become Amazon or Google,” said Biederman, who had to dash off to catch a flight. Only companies that can systematically create value for customers, which most of them aren’t doing right now, will survive. 

Aaron Jacobson, partner at NEA, said the history of technological innovation “is always overhyped in the near term and underhyped in the long term, and that will be true of AI.” So at some point there will be a correction and there will be cycles of pain around valuation and funding, “but ultimately, in 10 years, we’re going to have a lot of really big, impactful companies.”

Daniel Dart, founder and general partner of Rock Yard Ventures, had the boldest counter to fears about a bubble. He sees a total addressable market we can’t yet imagine. People think self-driving Waymos will replace Ubers, but Dart sees elementary schools and elderly care centers with Waymos waiting out front and that proves to him we’re still in the early innings. 

“You’re really going to tell me there aren’t going to be any trillion-dollar companies in 2030 or 2034? No one here is going to take that bet,” said Dart. “There is going to be so much value creation that it’s like the birth of fire.”

Coupang CEO resigns over historic South Korean data breach

Published

on



Coupang chief executive officer Park Dae-jun resigned over his failure to prevent South Korea’s largest-ever data breach, which set off a regulatory and political backlash against the country’s dominant online retailer.

The company said in a statement on Wednesday that Park had stepped down over his role in the breach. It appointed Harold Rogers, chief administrative officer for the retailer’s U.S.-based parent company Coupang Inc., as interim head.

Park becomes the highest-profile casualty of a crisis that’s prompted a government investigation and disrupted the lives of millions across Korea. Nearly two-thirds of people in the country were affected by the breach, which granted unauthorized access to their shipping addresses and phone numbers.

Police raided Coupang’s headquarters this week in search of evidence that could help them determine how the breach took place as well as the identity of the hacker, Yonhap News reported, citing officials.

Officials have said the breach was carried out over five months in which the company’s cybersecurity systems were bypassed. Last week President Lee Jae Myung said it was “truly astonishing” that Coupang had failed to detect unauthorized access of its systems for such a long time.

Park squared off with lawmakers this month during an hours-long grilling. Responding to questions about media reports that claimed the attack had been carried out by a former employee who had since returned to China, he said a Chinese national who left the company and had been a “developer working on the authentication system” was involved.

The company faces a potential fine of up to 1 trillion won ($681 million) over the incident, lawmakers said.

Coupang founder Bom Kim has been summoned to appear before a parliamentary hearing on Dec. 17, with lawmakers warning of consequences if the billionaire fails to show.

Park’s departure adds fresh uncertainty to Coupang’s leadership less than seven months after the company revamped its internal structure to make him sole CEO of its Korean operations. In his new role, Rogers will focus on addressing customer concerns and stabilizing the company, Coupang said.
