The Score is a weekly review of the biggest stock moves and the news that drove them.
Lululemon Athletica
Lululemon's founder is launching a proxy fight to overhaul the athletic-apparel company.
Chip Wilson said Monday that he had nominated three director candidates to the board as Lululemon searches for a new chief executive, confirming an earlier report by The Wall Street Journal.
The nominees are former On Running co-CEO Marc Maurer, former ESPN Chief Marketing Officer Laura Gentile and former Activision CEO Eric Hirshberg.
The Journal had previously reported that Wilson had hired financial advisers and was considering waging a proxy battle.
Elliott Investment Management has also been pushing for changes since it built a stake of more than $1 billion. The activist-investment firm has been pushing for former Ralph Lauren executive Jane Nielsen to take the reins as CEO, the Journal reported earlier in December.
Lululemon shares gained 1.7% Monday.
Meta Platforms
The global AI arms race continued to heat up with Meta's latest acquisition.
The Facebook parent agreed to buy artificial-intelligence startup Manus, a Singapore-based company with Chinese founders that conducts deep research and performs other tasks for paying users. Meta is paying more than $2 billion, The Wall Street Journal reported.
The deal is among the highest-profile examples of a major U.S. tech company buying an AI product developed in Asia's startup ecosystem. Manus has garnered millions of users since its spring launch.
Meta has been investing aggressively in AI to compete with Google, Microsoft and OpenAI, including a recruiting blitz last year that offered top AI talent multimillion-dollar paydays.
Meta shares gained 1.1% Tuesday.
Hecla Mining
Silver lost its shine this past week, as a wild year-end rally in the volatile precious-metals markets hit a rough patch.
Monday's selloff in precious metals sent silver futures to their steepest one-day decline in almost five years and weighed down mining stocks.
The slide came after CME Group increased margin requirements to ensure traders put down more cash on their bets. Exchange operators such as CME typically increase margin requirements after price run-ups in commodities.
For months, investors snapped up precious-metals funds as protection against a potential weakening of the U.S. dollar and uncertainty around richly valued tech stocks.
Shares of silver specialist Hecla Mining fell 5% Monday.
Delta Air Lines
Holiday snowstorms across large swaths of the U.S. caused a flurry of cancellations ahead of the New Year -- just in time for the year-end travel rush.
The weather-related snafus ramped up over the weekend. Nearly 300 flights to or from New York's John F. Kennedy International Airport, LaGuardia Airport and New Jersey's Newark Liberty International Airport were canceled on Saturday, Dec. 27, according to FlightAware. Hundreds more flights to and from those airports faced delays.
And then on Monday, more than 10,000 U.S. flights were delayed, according to flight-data specialist FlightAware. More than 900 flights within, into or out of the U.S. were canceled.
Delta Air Lines fell 1.9% Monday.
Nike
Nike investors celebrated on New Year's Eve, cheering another big investment from a top shareholder.
A week after Apple Chief Executive Tim Cook doubled his stake in the struggling athletic-gear giant, Nike CEO Elliott Hill on Tuesday disclosed purchase of roughly $1 million worth of shares.
Hill purchased 16,388 shares for an average price of $61.10 on Monday, according to the filing. His current stake totals 241,587 shares, he disclosed.
The iconic sneaker maker has fallen behind its competition, and its latest disappointing earnings report prompted a selloff before Cook's disclosure.
Nike shares gained 4.1% Wednesday.
Tesla
Elon Musk's Tesla is having a rough start to the New Year, as a Chinese rival took its crown as the world's biggest seller of electric cars.
Tesla on Friday reported that its annual deliveries fell 8.6% from the year before to roughly 1.6 million vehicles. Late Thursday, Chinese auto company BYD said it sold 2.26 million electric vehicles.
It's a reversal of fortunes for the competing car makers. Tesla was once the leading EV seller, while only a few years ago BYD's founder worried that the company might not survive.
On Friday, Tesla shares lost 2.6%.
