“Lots of research have pointed someplace between seven and eight hours of sleep being the magic quantity for us,” Gulati mentioned. “There may be clearly variability for everybody, however an excessive amount of sleep isn’t the difficulty.”

Investors only have themselves to blame as Jay Powell steals Christmas

Investors only have themselves to blame as Jay Powell steals Christmas

Unlock the Editor’s Digest for free

For markets, US Federal Reserve chief Jay Powell is the Grinch who stole Christmas. But the festive shakeout in bonds, currencies and stocks now under way in the wake of the US central bank’s latest pronouncements is a mini-crisis of investors’ own making.

Fed meetings, and the minutiae of its public statements, are always marquee events for investors, setting the tone across all major asset classes. Wednesday’s meeting, the last of 2024, always came with the potential for greater punch, given the timing — right on the cusp of Donald Trump’s second stint in the White House. 

The decision on rates itself — a quarter-point chop off the benchmark — was in line with expectations. But it went downhill from there, as the central bank’s apparent cooling on further cuts next year — an allusion to the potentially inflationary impact of Trump’s economic policies — has gone down like a mouldy mince pie.

US stocks nosedived, wiping out almost all of the gains in the S&P 500 benchmark index since Trump’s re-election day. The following morning brought a similar sea of red across Asian and European stocks too. The dollar popped higher, sending the euro and yen tumbling awkwardly hard, and US government bonds weakened, sending the yield on 10-year Treasuries forcefully above 4.5 per cent.

The Fed chair is facing some flak here. His comment in the post-meeting press conference that the year-end projection for inflation has “kind of fallen apart” is not the sort of self-assertion that investors seek in a Fed chair, and the pick-up in some inflation measures comfortably predates the reinauguration of Trump.

But markets are going through the wringer in no small part because the consensus among investors about the next steps for markets had become so intense — curdling hard around the themes of American exceptionalism in stocks and the vanquishing of inflation keeping bonds well supported. The path to an easy run in markets in 2025 had become exceptionally narrow and extremely crowded with like-minded views, and it has taken only a gentle push from the Fed to tip that out of balance.

The annual spectacle of year-ahead market outlooks from the big banks and asset managers demonstrated a near-unanimous set of views. Deutsche Bank is towards the top of the pack with its assessment that the benchmark S&P 500 index of heavyweight US stocks will ascend to 7,000 by the end of next year. After the overnight shock, that projection is 20 per cent above where we are now. It is punchy, but not wildly out of line. Core fundamental differences of opinion are hard to find. “The degree of uniformity in year-ahead projections has broken all previous records,” notes TS Lombard’s Dario Perkins.

The trouble with that was two-fold. First, it meant much, if not all, of the narrative was already baked in. Second, crowding around core themes tends to exaggerate the scale of market reactions when stuff goes wrong. Enter Powell stage left.

“Everyone’s portfolio is pointed towards US exceptionalism,” said Mike Riddell, a portfolio manager on Fidelity’s Strategic Bond Fund, speaking with some foresight the week before the Fed decision. “The consensus can be right, and we don’t see much to derail it. But if you see anything to move the narrative, you can get really violent market moves.”

We have been here before, in a range of different markets, but that does not prevent investors from making the same mistake over and over again. This time last year, Powell caught the market off guard in the opposite direction, dropping a hint of interest rate cuts that investors went on to exaggerate hugely out of proportion.

Crowded bets among investors also stung in early August, when a downbeat US labour market report blasted in to several popular and correlated market bets. In late September, deeply unloved Chinese stocks rocketed higher after Beijing unleashed stimulus measures to try and turn the hobbled economy and markets around. Investors had given China such a wide berth that stocks leapt 40 per cent in just a few days as funds piled in to a narrow entrance.

The latest ructions are a useful reminder that despite the disarming simplicity of the American exceptionalism theme, rakes are scattered all over markets for investors next year.

The assumption that the US economy will sail through the first year of Trump 2.0 is brave. Ignoring the (actually pretty obvious) banana skins, particularly around inflation, is “the ultimate ‘trust me’ trade” says Greg Peters, co-chief investment officer for PGIM Fixed Income. “It seems off to me.”

Now, investors should not assume that the Christmas holiday season will put all this angst to bed. As the final days of 2018 showed, portfolios can and do shake around wildly even when a lot of core markets are shut, on half-days, or on the go-slow. If anything, thinned-out trading volumes at this time of year can make matters worse. 

Some fund managers will be feeling sore about this year-end beating. But Powell has done us all a favour in reminding us that next year will not be for the faint of heart, and the wisdom of crowds is not always your friend.

Wisconsin school shooting victims named as teacher Erin West and student Rubi Vergara

Wisconsin school shooting victims named as teacher Erin West and student Rubi Vergara

Tributes have been paid to the two victims who died in the shooting at the Abundant Life Christian School in Madison, Wisconsin, on Monday, who have been named as 42-year-old teacher Erin M. West and 14-year-old student Rubi P. Vergara.

The Dane County Medical Examiner’s office confirmed their identities in a press release Wednesday night, while in a separate statement, the school said, “our hearts are heavy with these losses.”

The suspected shooter, 15-year-old Natalie Rupnow, a freshman at the school who was also known as Samantha, died on the way to hospital on Monday from an apparent self-inflicted gunshot wound, police said.

“ALCS is a better school for the work of Erin West. She brought her love of Jesus and love of people to our staff and school family all wrapped in a hug and topped with a smile,” the school’s statement said.

The school said West worked as a substitute teacher for three years before taking a full-time staff role as an in-house substitute teacher and coordinator, “a role tailor made for her abundant skills and breadth of knowledge.”

“She served our teachers and students with grace, humor, wisdom, and — most importantly — with the love of Jesus. Her loss is a painful and deep one and she will be greatly missed not just among our staff, but our entire ALCS family,” the statement added.

Rubi Vergara, a 9th grade student, had been at the school since kindergarten and was described as popular and a keen volunteer.

“Her gentle, loving, and kind heart was reflected in her smile. Rubi was a blessing to her class and our school. She was not only a good friend, but a great big sister,” the school said.

“Often seen with a book in hand, she had a gift for art and music. Yet, it was Rubi’s love for Jesus that shined brightest and she shared His love with others by volunteering faithfully. She will be missed deeply by her teachers and fellow students,” the statement added.

An online obituary uploaded to a local funeral home website said Vergara loved art, singing and playing keyboard in her family’s worship band. “She shared a special bond with her beloved pets, Ginger (cat) and Coco (dog),” the obituary said.

The funeral home said a service for Vergara would be held on Saturday at 11 a.m. CST (12 a.m. ET) and would be livestreamed online.

The police investigation into the shooting continues. Authorities said Wednesday night that the two unidentified students who received life-threatening injuries remain in a local hospital, while the four people who were treated in hospital for minor injuries sustained in the shooting have been discharged.

Police said that the shooter opened fire in a second-floor classroom “during a study hall for mixed graders.”

Two guns were found at the school, but only one was used in the shooting, police said.

Police said they were working to establish a motive and said they were aware of the suspect’s alleged social media activity and “documents and photos circulating the internet,” that have yet to be verified.

Detectives want to speak to any who may have interacted with Rupnow in the days or weeks before the shooting — they can contact police anonymously through Madison Area Crime Stoppers at p3tips.com or by calling 608-266-6014.

Perplexity’s value triples to $9bn in latest funding round for AI search engine

Perplexity’s value triples to bn in latest funding round for AI search engine

Unlock the Editor’s Digest for free

Perplexity, an artificial intelligence-driven search engine, has closed its fourth funding round this year, tripling its valuation to $9bn as it seeks to compete with offerings from Google and OpenAI.

The $500mn round was led by Institutional Venture Partners, with involvement from Nvidia, New Enterprise Associates, B Capital and T Rowe Price, according to multiple people with knowledge of the deal. Previous investors have included SoftBank’s Vision Fund 2, Nvidia and Amazon founder Jeff Bezos, as well as several prominent names from the AI industry such as OpenAI co-founder Andrej Karpathy and Meta’s chief AI scientist Yann LeCun.

The San Francisco-based group has grown rapidly this year, with its product receiving hundreds of millions of queries a month. It has 15mn monthly active users with most of that traffic coming from the US.

The new funding will help Perplexity compete with west coast rivals in an increasingly fierce fight for engineers. “The talent war for AI is like no other time before,” according to Ali Ghodsi, co-founder and chief executive of Databricks, the AI and data analytics company that announced a $10bn fundraising round on Tuesday.

Perplexity is seeking to capitalise and improve on the search advertising system pioneered by Google, in which marketers bid to have a sponsored link placed against search queries. It is in talks with major brands to pilot advertising on its platform.  

In a sign of growing competition in the space, AI companies have recently targeted the search market by linking up chatbots to the internet. This week, OpenAI rolled out web searching for its popular ChatGPT product, while Anthropic’s Claude can perform searches through a feature called “computer use”.

Google and Microsoft, which are leaders in the $300bn digital advertising world, have also recently incorporated large language models, which power AI chatbots and make results more conversational, into their search offerings.

The latest round has pushed Perplexity’s valuation higher by nine-fold since the start of the year, in another sign of how hot start-ups developing new AI tools can draw in hundreds of millions or even billions of dollars in investment.

After OpenAI’s $6.6bn fundraising in October — one of the largest in Silicon Valley — one person close to the company said Perplexity was inundated with unsolicited interest from new investors.

Run by former Google intern Aravind Srinivas, Perplexity raised $250mn this summer, on top of previous funding rounds in January and April.

Perplexity makes money through subscriptions. It says its annualised revenues — a projection of full-year revenues based on extrapolating the most recent month’s sales — have grown from $5mn in January to $35mn in August.

The spate of deals for lossmaking AI start-ups has stoked concern among some investors that rising valuations in the sector show all the hallmarks of a bubble, however. But even those who argue most AI valuations are increasingly detached from reality are willing to stake bets on companies they believe could be winners.

Perplexity and T Rowe Price declined to comment. IVP, B Capital, NEA and Nvidia did not immediately respond to a request for comment. The closing of the round was first reported by Bloomberg.
