US stocks end week on a soft note

But the S&P 500 still posted a gain for the week.

8/15/25 3:26PM

The S&P 500 fell 0.3% while the Nasdaq 100 and Russell 2000 gave back 0.5% on Friday.

Healthcare was the best-performing S&P 500 sector ETF, and there was one big reason why:

UnitedHealth Group enjoyed its biggest daily gain since March 2020, soaring double digits after filings revealed Warren Buffett’s Berkshire Hathaway bought the stock in the second quarter while David Tepper’s Appaloosa Management added to its position in the beleaguered healthcare giant.

Tech, industrials, utilities, and consumer discretionary sectors all ended in the red.

Tesla fell amid fresh data showing its US EV sales were down 1% year on year in July.

Meanwhile, Chinese EV maker Nio surged after announcing that it’s started delivering cars to customers in the Netherlands and Norway, its first foray into the European market.

Semi equipment maker Applied Materials got clobbered after issuing ugly guidance for the current quarter.

Hims & Hers dropped after Bloomberg reported that the FTC is investigating its business practices.

Joby Aviation initially got a big boost after announcing it completed its first US test flight between two airports, but gave all that up and then some as the achievement was apparently deemed insufficiently impressive by investors.

Roblox tanked after the Louisiana attorney general filed a lawsuit against the company, calling it “the perfect place for pedophiles.”

SharpLink Gaming also tumbled after reporting a second-quarter loss.

Opendoor got a boost from the exodus of CEO and Chair Carrie Wheeler, who stepped down amid intense criticism from high-profile names within the shareholder base.

Strategy jumps as MSCI allows digital asset treasury companies to stay in global indexes

In a massive reprieve for Strategy, index provider MSCI is letting digital asset companies stay in its benchmarks, sending shares sharply higher in after-hours trading.

The index provider had floated a proposal in which firms where crypto holdings are more than 50% of assets would be excluded from its global indexes, but has decided not to proceed with this for now.

“MSCI has determined at this time not to implement the proposal to exclude digital asset treasury companies (‘DATCOs’) from the MSCI Global Investable Market Indexes (‘MSCI Indexes’) as part of the February 2026 Index Review,” per a statement.

Getting kicked out of key indexes would have caused funds to flow out of Strategy, the largest digital asset treasury company, and its peers.

“At this time,” of course, means the door is open to reconsidering this down the road, as MSCI plans on having a broader review and consultation on the treatment of DAT companies.

“Distinguishing between investment companies and other companies that hold non-operating assets, such as digital assets, as part of their core operations rather than for investment purposes requires further research and consultation with market participants,” according to MSCI.

Rocket Lab surges to second straight record-high close

Retail favorite Rocket Lab closed at a new all-time high on Tuesday, continuing a remarkable run over the last month that has carried the launch services provider and aspiring Space X competitor up more than 70% over the last month (compared to its close of $49.06 on December 5).

Rocket Lab saw elevated options activity during its run-up today, with well over 3.5x the 90-day average in options volume changing hands over the course of the day.

Other space plays such as AST SpaceMobile and EchoStar surged today.

Despite being a money-losing company — it’s never turned an annual profit as a public company — Rocket Lab’s share price has soared nearly 1,500% over the last two years, generating tons of loyalty and enthusiasm among retail investors.

In fact, Goldman Sachs has made Rocket Lab the heaviest weighting in the latest iteration of its GS Memes basket of thematic stocks, just ahead of AST SpaceMobile, showing how enamored traders have become of such space stocks.

JetBlue takes off on bullish options activity

Low-cost airline JetBlue is up more than 8% on Tuesday, on pace for its biggest daily gain since August. If the price momentum holds, Tuesday will mark JetBlue’s sixth-best trading day of the past 52 weeks.

The carrier is being propelled by bullish options activity, with more than 53,000 call options changing hands as of 12:14 p.m. ET, nearly 4x the 20-day average for a full session.

JetBlue closed up 4.6% on Monday, as traders appeared to price in medium-term oil supply relief due to the possibility of Venezuela’s reserves getting more developed amid tensions with the US.

Moderna rallies after BofA raises its price target to $24 from $21

Moderna rose on Tuesday after Bank of America analysts raised their price target for the ailing biotech behind the COVID-19 vaccine, painting a rosy picture of the products in its pipeline.

BofA kept Moderna’s “underperform” rating but raised its price target to $24 from $21, which now accounts for “refreshed revenue builds for lead assets.” Analysts said the company’s cost-cutting measures, paired with potential new revenue from its investigatory oncology vaccines, could bring it back to profitability in the coming years.

Moderna is best known for being tapped by the US government to quickly develop a vaccine for COVID-19 in 2020, a product that remains its single source of revenue. The company has yet to bring new products to market and is now faced with a second Trump administration hostile to that product.
