Invest like you shop? For men, that's a mistake
So say the authors of A Man's World? Consumption-based Investment in the Mutual Fund Industry, a recent study showing male and female fund managers tend to back sectors they personally consume.
For men that means energy (the most lopsidedly male-weighted sector), finance, utilities, cars and alcohol. For women it's healthcare and personal care.
Portfolio choices, it seems, echo shopping lists.
This gendered tilt isn't harmless. Portfolios heavy on 'masculine' sectors tend to underperform.
The researchers built a Portfolio Masculinity Index and found a clear pattern: the more macho the fund, the worse the results. Testosterone, it seems, is no substitute for due diligence.
Capital allocation reflects who's allocating it. With men dominating the industry – women manage only a sliver of assets – the market risks inefficiently funnelling funds into sectors they happen to like.
The researchers say gender parity would see capital drain from fossil fuels and finance, and flow towards healthcare and tech. Less diesel, more diagnostics.
The broader lesson? Investment decisions shaped by gendered habits may skew markets and sap returns.
Buying what you know is one thing; buying what you consume is another.

Data credibility fears fuelled after Trump orders firing of labour official
Sharp downward revisions to jobs data on Friday, followed by Donald Trump 's sudden order to fire the head of the Bureau of Labor Statistics , stoked investor fears about the integrity of economic data and the Fed's ability to read the true state of the US economy. News of a surprise weakening in the US labour market last month jolted investors, while revisions to job figures for the past two months raised worries the US central bank may have been flying blind in recent months and may need to play catch-up with interest rate cuts, investors said. Fed governor Adriana Kugler's early resignation from her term on Friday also potentially shakes up what was already a fractious succession process for Fed leadership amid difficult relations with Mr Trump. The US president on Friday renewed his call for Federal Reserve chair Jerome Powell to resign. 'Powell should resign, just like Adriana Kugler, a Biden Appointee, resigned,' Mr Trump said in a post on Truth Social. READ MORE 'Kugler's resignation allows the president to further shape the FOMC [Federal Open Market Committee] in his own image,' said Jamie Cox, managing partner at Harris Financial Group. Nonfarm payrolls increased by 73,000 jobs in July after rising by a downwardly revised 14,000 in June, the Labor Department's Bureau of Labor Statistics said in its employment report on Friday. Economists polled by Reuters had forecast payrolls increasing by 110,000 jobs after rising by a previously reported 147,000 in June. The report comes two days after the US central bank left unchanged its benchmark interest rate and avoided signalling imminent rate cuts, dialling back market expectations for an easing at the next policy meeting in September. That changed dramatically on Friday, with odds for a 25 basis point cut in September jumping to about 81 per cent after the data from 38 per cent on Thursday, according to CME Group data. 'The Fed's job is becoming increasingly difficult based on the deterioration of the economic data,' said Matthew Miskin, co-chief investment strategist at Manulife John Hancock Investments. 'These revisions are massive and really are a game changer to the Fed's reaction function, and so I think this Fed meeting is one that they'd like to revise.' Mr Trump on Friday said, without evidence, that numbers contained in the July jobs report from the Bureau of Labor Statistics were rigged. 'In my opinion, today's Jobs Numbers were RIGGED in order to make the Republicans, and ME, look bad,' Trump said in a Truth Social post. He ordered that the commissioner of the Labor Department's Bureau of Labor Statistics Erika McEntarfer be fired after the data release. 'It's definitely a case of shooting the messenger,' said Dean Smith, chief strategist at FolioBeyond. 'Firing the head of BLS is not going to improve data collection and dissemination ... it's going to undermine confidence in the data going forward,' he said. Revisions for May and June came in well above the norm, the Bureau of Labor Statistics said. It gave no reason for the revised data but noted that 'monthly revisions result from additional reports received from businesses and government agencies since the last published estimates and from the recalculation of seasonal factors.' May's nonfarm payroll gain was slashed by 125,000, from 144,000 to just 19,000, while June's downward revision was by 133,000. In total, employment over the two months is now 258,000 lower than initially reported. 'It is painfully obvious that the US government has an improper model for payroll calculations,' said Michael Green, portfolio manager at Simplify Asset Management. 'If you don't have reliable data, you make bad policy.' Spencer Hakimian, founder of macro hedge fund Tolou Capital Management, said lay-offs across several government departments, part of Mr Trump's plans to reduce wasteful government spending, have prompted him to rely more heavily on alternative measures of economic strength than just government data, such as credit card data, and data from Truflation, an independent inflation index alternative to official government inflation measures. Mr Powell said in a press conference on Wednesday the labour market remained strong, and that the central bank was still in the early stages of grasping how Mr Trump's overhaul of import taxes and other policy shifts would play out for inflation, employment and economic growth. 'Had those figures been the initial prints a month or two ago it would have significantly changed the labour market narrative over the entire summer,' said Adam Hetts, global head of multi-asset and portfolio manager at Janus Henderson Investors, in a note. Treasury yields, which move inversely to bond prices, dropped on Friday, with benchmark 10-year yields down by a whopping 15 basis points to 4.22 per cent – their biggest daily drop since April. Two-year yields were down by about 25 basis points to 3.69 per cent, registering their biggest daily decline since August last year. Stocks declined too, also weighed on by Mr Trump's latest tariffs salvo. The benchmark S&P 500 index lost 1.6 per cent, bringing stocks to their lowest since early July. The deterioration in the labour picture comes amid steep US tariffs on large trade partners that – while not as high as feared earlier this year – are still largely expected to worsen inflation and slow economic activity.

Tesla ordered by Florida jury to pay $329m in fatal crash
A Florida jury on Friday found Tesla liable in the 2019 fatal crash of an Autopilot-equipped Model S car and ordered Elon Musk 's automaker to pay $329 million (€280 million) to the family of a deceased woman and an injured survivor. Jurors in Miami federal court ordered Tesla to pay $129 million in compensatory damages and $200 million in punitive damages to the estate of Naibel Benavides Leon and to her former boyfriend Dillon Angulo. Lawyers for the plaintiffs said the trial was the first involving the wrongful death of a third party resulting from Autopilot. The plaintiffs had sought $345 million. Tesla has faced many similar lawsuits over its vehicles' self-driving capabilities, but they have been resolved or dismissed without getting to trial. A judge rejected Tesla's efforts to dismiss the case earlier in the summer, and experts said this may encourage other litigants against the EV maker. READ MORE Friday's verdict could impede efforts by Mr Musk, the world's richest person, to convince investors that Tesla can become a leader in so-called autonomous driving for private vehicles as well as robotaxis it plans to start producing next year. Shares fell 1.8 per cent on Friday. Tesla plans to appeal, according to published reports. The Austin, Texas-based company and its lawyers did not immediately respond to several requests for comment. The trial concerned an incident in 2019 where George McGee drove his 2019 Model S at about 100km/h through an intersection into the victims' parked Chevrolet Tahoe as they were standing beside it on a shoulder. Mr McGee had reached down to pick up a mobile phone he dropped on his car's floorboard and allegedly received no alerts as he ran a stop sign and stop light before hitting the victims' SUV. 'We have a driver who was acting less than perfectly, and yet the jury still found Tesla contributed to the crash,' said Philip Koopman, a Carnegie Mellon University engineering professor and expert in autonomous technology. 'The only way the jury could have possibly ruled against Tesla was by finding a defect with the Autopilot software. That's a big deal.' Benavides Leon was allegedly thrown 75ft to her death, while Mr Angulo suffered serious injuries. 'Tesla designed Autopilot only for controlled-access highways yet deliberately chose not to restrict drivers from using it elsewhere, alongside Elon Musk telling the world Autopilot drove better than humans,' Brett Schreiber, a lawyer for the plaintiffs, said in a statement. 'Today's verdict represents justice for Naibel's tragic death and Dillon's lifelong injuries,' he said. Last month Tesla posted its biggest quarterly sales decline in more than a decade, and profit fell short of Wall Street forecasts. – Reuters (c) Copyright Thomson Reuters 2025

The Irish Times view on Trump's week: out of the rough for now
This week, not for the first time, Donald Trump was accused of cheating at golf. Video footage from a round at a Scottish course appeared to show an aide surreptitiously placing a ball in a more favourable position. The metaphor is almost too easy. In both golf and politics, the US president plays a game in which rules are negotiable and perception trumps process. Yet even by the standards of his tumultuous presidency, Trump had reason to feel buoyed this week. Two significant trade deals – one with the European Union, the other with Japan – allowed him to claim vindication for his unorthodox approach to international economics. He has long argued that the global trading system short-changes the US and that tough talk and tougher tariffs would redress the balance. His critics, including most mainstream economists, have warned of retaliation, inflation and lost jobs. But, so far, the economic data has not borne out those dire predictions. Stock markets remain steady and recent opinion polls suggest Trump is regaining public trust in his handling of the economy. Flush with this perceived success, he has pushed further. New and broader tariffs were announced on Friday, targeting countries he claims have taken advantage of American goodwill such as Canada and Brazil. At the same time, he has signalled a shift on Russia, threatening imminent fresh sanctions unless progress is made on the Ukraine conflict. But warning signs are emerging. Revised labour market data revealed a marked slowdown in job creation over the last quarter. That followed a disappointing GDP report indicating that consumer spending – a key pillar of US growth – is cooling. The Federal Reserve, long a punching bag for the president, may now be forced to re-evaluate its reluctance to cut interest rates when it meets in September. READ MORE The bigger picture remains murky. Few details of the much trumpeted trade deals have been finalised. Implementation timelines are vague. So far, the primary impact of Trump's tariff policy has been to inject uncertainty into the global economy, not least in Ireland. The Department of Finance warned this week that the latest round of US tariffs could reduce Irish job creation by as much as 70,000 over the next five years. This is a serious threat, though not an existential one. The true risk lies in the White House's apparent addiction to drama. If the remainder of Trump's presidency continues to be defined by impulse, personal grievance and sudden policy shifts, then this current period of relative calm could prove fleeting. For now, he may feel like a winner. But in politics as in golf, it is not how you start that counts. It is where the ball finally comes to rest.
