Why Newsrooms Often Operate by Story Instinct, Not a House View

Wigglesworth disputes the idea that owners, advertisers, or a unified political position routinely determine journalists’ coverage. He says newsroom behavior is more often driven by a professional culture that classifies developments as good or bad stories, for better and worse.

  • Newsrooms often lack a unified house view
  • Journalistic culture can be mistaken for political ideology
  • Story value frequently drives coverage decisions
  • Commercial explanations can overstate owner influence

“We think in terms of good and bad stories, rather than pandering to owners.”

Bond ETFs Survived Their March 2020 Stress Test Better Than Expected

Wigglesworth entered the pandemic crisis as a cautious ETF skeptic and expected serious failures in bond products. He concluded instead that credit ETFs were resilient, may have helped absorb market stress, and came closer to functioning as a pressure release than causing the crisis.

  • Bond ETFs faced extreme pressure in March 2020
  • Wigglesworth expected more structural failures
  • Traditional bond mutual funds may have been closer to mass closure
  • Federal Reserve intervention supported markets broadly
  • Credit ETFs may have dampened some financial-system stress

“I was actually positively supplirized by the resiliency of bond ets in March.”

Robin Wigglesworth · 32:03

“credit ets were at worst not a contributor to the issues, and actually probably in some respect helped dampen some of the issues”

Meme-Stock Mania Did Not Reverse the Passive-Investing Shift

Free trading, gamified apps, and social media changed retail participation and produced an exceptional burst of active trading. Yet passive products continued attracting substantially more capital, including through automated retirement and target-date allocations, while most active managers remained likely to underperform over longer periods.

  • Hope and the desire to get rich sustain speculative manias
  • Technology has permanently lowered barriers to active trading
  • Active funds briefly returned to inflows
  • Passive funds still attracted much more money
  • Automated retirement flows reinforce indexing’s growth

“fundamentally, I think hope springs eternal. Everybody thinks and wants to try and beat the index.”

“most of them will end up losing a lot of money and it will be a very sad denial.”

Hot Take1:05:14

Systematic and Discretionary Investing Are Converging

Temporary performance weakness does not change Wigglesworth’s expectation that investors will use more technology and systematic processes. He predicts discretionary managers will become more quantitative while quant managers add judgment-based overlays, progressively weakening the boundary between the two styles.

  • Quant coverage follows dramatic performance stories
  • Technology use in investing is structurally increasing
  • Market understanding increasingly requires quant literacy
  • Discretionary investors are adopting systematic tools
  • Quant managers may add discretionary judgment

“whether way our investor is going to be using more technology to invest more systematically in the future or less, And I think the direction…”

Robin Wigglesworth · 1:06:11

“this kind of always a little bit blurry line between systematic and discretionary investing is is going to get washed out”

Hot Take1:07:19

Direct Indexing Is Useful—but Not Indexing 3.0

Direct indexing can customize portfolios by excluding objectionable companies or reducing exposure to an investor’s employer. Wigglesworth expects strong growth, particularly through financial advisers, but argues that most people value simplicity too much for it to displace broad index funds and ETFs.

  • Customization is a genuine investor demand
  • Direct indexing can remove unwanted holdings
  • It can reduce employer-related concentration risk
  • Advisers may find it especially useful
  • Most investors still prefer simple broad funds

“the vast majority of people still want simplicity and especially in their financial products.”

Why State Street Lost Its Early ETF Advantage

State Street treated ETFs as a useful extension of an institutional indexing business rather than a transformative portfolio platform. Barclays Global Investors recognized that ETFs could serve as modular portfolio building blocks, secured major funding, and rapidly launched products to capture incumbent advantages.

  • State Street underestimated the product category
  • Institutional indexing fees shaped its expectations
  • BGI treated first-mover scale as strategically important
  • Rapid product launches established a broad ETF franchise
  • Vanguard later benefited from strong retail trust

“They didn't see the potential of ets as these basically lego like bricks that you can build broad portfolios with.”

Robin Wigglesworth · 22:44

“if your first you can win, you can become the incumbent.”

Why Bank Distribution Slows Passive Investing Outside America

Passive adoption varies internationally because investment products reach customers through different distribution systems. In markets where banks control distribution, they have an incentive to recommend their own higher-fee funds rather than cheap products operated by outside managers.

  • Passive adoption depends partly on distribution structure
  • European banks are central fund distributors
  • Banks often favor proprietary, higher-fee products
  • Active managers may fare better in less efficient markets
  • Long-run fee-adjusted data still favors passive growth

“banks tend to not want to steer people into cheap products managed by other people.”

The Real Concern Behind the Index-Fund Common-Ownership Debate

Wigglesworth is skeptical that index managers coordinate portfolio companies or cause overt price fixing. He treats the stronger concern as long-term voting concentration: economies of scale may continually enlarge BlackRock, Vanguard, and State Street until a few firms cast a very large share of corporate votes.

  • There is no evidence of direct price-fixing coordination
  • Airline evidence is difficult to separate from industry consolidation
  • CEO incentives still favor company-level performance
  • The Big Three already cast a significant share of votes
  • Indexing economics may intensify ownership concentration

“I completely agree that there is no cut how behavior whatsoever going on.”

How Islamic Reinsurance Launched Wigglesworth’s Journalism Career

Wigglesworth abandoned plans to become a physicist after deciding he lacked the mathematical ability to excel. A job in Dubai led him to interview local sheikhs about Islamic reinsurance immediately after arriving, and being paid to learn from interesting people made him fall in love with journalism.

  • He initially wanted to become a physicist
  • He moved to Dubai despite knowing little about finance
  • His first assignment covered Islamic reinsurance
  • The pleasure of learning became the appeal of journalism

“I loved learning about new things, and here I was getting paid to learn about something new and interesting from interesting people.”

Why the History of Passive Investing Needed a Full Book

Passive investing began as a recurring theme in Wigglesworth’s market reporting, but its effects extended beyond fund fees into trading desks and market structure. Research revealed a surprisingly dramatic history populated by combative innovators who were rejected by their own industry, making the subject both important and narratively compelling.

  • Passive investing reshaped more than investment fees
  • Banks and trading desks adapted to the trend
  • Its history contained conflict and overlooked personalities
  • The combination of importance and human drama justified a book

“when you're a journalist and you have a combination of an important story and a fun story, you just you have everything you need”

The Index Fund Began as Bogle’s Escape Route

Vanguard’s mutual structure and retail index fund did not emerge from a perfectly executed master plan. After Bogle lost control of Wellington, the administrative company owned by the funds gave him a platform, while an unmanaged index fund offered a way around restrictions that left investment management with Wellington.

  • Bogle was removed as Wellington’s CEO
  • The fund boards created an administrative company
  • Investment management initially remained with Wellington
  • An unmanaged index fund provided a strategic loophole
  • Bogle’s embrace of indexing was more complicated than later accounts suggested

“It was essentially a ploy to get out from under the thumb of the Boston partners and it worked quite interesting.”

How an Aging Exchange Innovator Helped Create the ETF

American Stock Exchange executive Nate Most and Stephen Bloom proposed listing tradable index funds to restore relevance to the AMEX. Bogle rejected intraday trading as contrary to buy-and-hold investing, so the team partnered with State Street, while Canadian exchanges moved faster and listed the first ETF before the US product cleared regulatory delays.

  • The AMEX needed products that could restore trading activity
  • Most and Bloom proposed exchange-traded index funds
  • Bogle rejected the product’s trading orientation
  • State Street became the US partner
  • Canadian exchanges launched the first ETF

“It was just anathema to him, the idea that you trade a fund in and out all the time.”

The Acquisition That Turned BlackRock Into an Asset-Management Giant

Wells Fargo’s pioneering quantitative investment unit evolved through mergers into Barclays Global Investors, where the ETF franchise became iShares. During the financial crisis Barclays sold BGI to BlackRock, transferring a highly profitable indexing, ETF, and quantitative-investing platform that became central to BlackRock’s scale.

  • Wells Fargo’s early index unit became the ancestor of BGI
  • WEBs evolved into iShares
  • Barclays sold BGI during the financial crisis
  • BlackRock acquired indexing and quantitative capabilities
  • The deal became one of asset management’s greatest acquisitions

“certainly the greatest deal in the history of ATM management”

The Lucky Breaks That Made Vanguard Possible

Vanguard’s rise depended on a chain of contingent events: Bogle encountered an article about mutual funds, joined Wellington, made a damaging merger, was fired, and later encountered Paul Samuelson’s call for a retail index fund. Wigglesworth uses the history to show how successful people can exploit luck without having designed every event in advance.

  • Bogle discovered mutual funds by chance at Princeton
  • His Wellington merger ultimately led to his dismissal
  • The dismissal created the conditions for Vanguard
  • Samuelson’s article helped redirect the new company
  • Skill mattered, but timing and serendipity were indispensable

“we sometimes over attribute it to the brilliance of the people involved, and under a attribute it to just blind luck sometimes.”

“his sacking actually ended up being the making of him.”

Indexing Benefits Investors Who Never Buy an Index Fund

The greatest system-wide benefit of indexing may be the price competition it imposed on the investment industry. Wigglesworth argues that even investors using active mutual funds or hedge funds benefited as average fees declined under pressure from cheap passive alternatives.

  • Indexing created industry-wide price competition
  • Its benefits extend beyond passive investors
  • Lower fees compound into substantial retirement savings
  • Aggregate savings may total trillions of dollars

“everybody on the planet pretty much who has savings has benefited from the indexing revolution, even if they don't invest in index funds”

How to Prepare for a Career in Financial Journalism

Wigglesworth recommends extensive reading, specialist expertise, practical experience, and at least some coding literacy. He considers subject knowledge and internships more valuable than the classroom component of a journalism degree and urges the profession to recruit from a wider range of backgrounds.

  • Read extensively
  • Develop a specialist niche
  • Learn coding or understand data tools
  • Prioritize practical experience
  • Build subject-matter expertise outside journalism
  • Increase socioeconomic and cultural diversity

“read a lot, a lot, and maybe develop a niche that that you know really well”

Robin Wigglesworth · 1:14:28

“learning to code or at least understanding some of those fives is incredibly helpful.”

Takeaway1:17:18

The Uncomfortable Career Truth: Every Job Is Sales

Wigglesworth says producing good work does not guarantee that others will notice or reward it. Professionals eventually learn that they must communicate, advocate for, and create support for their work rather than relying entirely on merit to speak for itself.

  • Quality work is not automatically recognized
  • Chance influences whether merit receives attention
  • Professional success requires communicating value
  • The lesson applies beyond formal sales roles

“every job is sales.”

Robin Wigglesworth · 1:17:27

“you always think that, you know, good work will always get recognized, and it can. Again, you can be lucky or you can be unlucky.”
