Market Recap

Stocks Slide Again as Oil Spike and Rising Yields Weigh

The S&P 500 fell 0.49% to 7,635.64, the Dow dropped 372.72 points (0.71%) to 52,413.35, and the Nasdaq Composite slid 0.70% to 26,236.03 in Wednesday trading, marking a second straight session of losses. The selloff was driven by a jump in oil prices tied to escalating U.S.-Iran tensions and a fresh climb in Treasury yields, which pressured richly valued technology and growth names the hardest.

Brent Crude Tops $100 a Barrel for First Time Since July

Brent crude, the international oil benchmark, rose about 2.6% to roughly $100.44 a barrel — its first trip above the $100 mark since July — while U.S. benchmark WTI crude gained about 2% to near $94.92. The move followed fresh military exchanges between the U.S. and Iran and a Houthi attack on Saudi Arabian energy facilities that forced temporary shutdowns, raising fears that Middle East supply disruptions could worsen and reviving concern about the Strait of Hormuz, the corridor through which a large share of the world's seaborne oil passes.

Rising Yields Punish Big Tech; Alphabet, Salesforce, Nike Lead Decliners

The 10-year Treasury yield pushed back above 4.80% — near its highest level since November 2023 — adding pressure to high-valuation growth stocks. Alphabet fell about 3.2%, Salesforce dropped roughly 3.0%, and Nike slid about 2.2%, among the session's worst performers. Higher long-term rates raise the discount applied to future profits, a dynamic that weighs disproportionately on richly valued technology and software companies.

SpaceX Faces Up to $47 Billion in Insider Selling as Shares Unlock

About 319 million SpaceX shares became eligible for sale on Wednesday as an early lockup restriction expired, representing as much as $47 billion in potential selling pressure based on the stock's roughly $148 share price. CEO Elon Musk remains barred from selling until 366 days after SpaceX's public debut, but other early-eligible insiders can now sell. Analysts still rate the stock a Moderate Buy, with an average price target implying more than 56% upside, and the stock is also positioned for a Nasdaq-100 rebalancing later this month that's expected to bring roughly $15.5 billion in passive index buying.

Yields Near 4.8% as Fiscal Worries Build Ahead of Key Inflation Data

Treasury yields are running hot in part because of growing fiscal concerns: the national debt has climbed above $40 trillion, more than $8.4 trillion in government securities are set to roll over by year-end, and September could be a record month for high-grade corporate bond issuance — meaning Washington and corporate borrowers are competing for the same pool of investor demand. The Treasury Department's efforts to talk yields lower, including buyback operations, have so far failed to bring the 10-year down meaningfully. Markets are also digesting last week's stronger-than-expected August jobs report, which pushed fed funds futures toward pricing in a possible rate hike at the Fed's September 15-16 meeting rather than a cut. Investors now turn to Thursday's Producer Price Index and Friday's Consumer Price Index for the next read on inflation.

Concept of the Day

Term Premium

The term premium is the extra yield investors demand for holding a longer-maturity bond instead of rolling over a series of shorter-term ones. In theory, a 10-year Treasury yield can be broken into two pieces: the average short-term interest rate investors expect over the next decade, plus a term premium that compensates them for the extra risk of locking up money for longer — the risk that inflation, rates, or the government's fiscal position could shift unexpectedly during that time. When the term premium rises, long-term yields can climb even if the Fed isn't raising short-term rates at all. That's largely what's happening right now. Fed funds futures are debating a hike or a hold at the September 15-16 meeting, but the bigger driver of the 10-year yield pushing back above 4.80% is a separate worry: the U.S. government's growing borrowing needs. National debt above $40 trillion, more than $8.4 trillion in Treasury securities rolling over by year-end, and a potentially record month of corporate bond issuance are all competing for the same pool of investor demand. Treasury buyback operations aimed at supporting demand and capping yields have so far failed to bring the 10-year down meaningfully, which is a sign investors are pricing in more compensation for supply and fiscal risk — a rising term premium — not just rate expectations. For investors, distinguishing between rate expectations and term premium matters because they call for different responses. If yields are rising because the market expects a stronger economy or a more hawkish Fed, that's one story. If yields are rising because investors want more compensation for absorbing a flood of government debt, that's a structural, supply-driven story that can persist even after the Fed starts cutting — and it's a headwind for any long-duration asset, from 30-year bonds to unprofitable growth stocks, that isn't going away just because a single data point (like Thursday's PPI or Friday's CPI) comes in soft.

Why it matters

Today's Treasury move is a live example: the 10-year yield is back above 4.80% even though the immediate rate debate is about whether the Fed hikes or holds next week, which points to the fiscal and supply story — not just monetary policy — as the bigger driver. For investors, that distinction determines whether today's high rates are a temporary bump tied to this week's data or a more durable feature of the market that persists regardless of what the Fed does.
