Market Recap

Dow's win streak wobbles as chip-guidance jitters fade into midday Thursday trading

In midday trading Thursday, the Dow Jones Industrial Average slipped 0.23% to 54,226.07, putting its five-session winning streak at risk after Wednesday's record close at 54,349.12 (+0.49%). The S&P 500 and Nasdaq Composite, which both pulled back Wednesday - the S&P fell 0.17% to 7,723.55 and the Nasdaq dropped 0.83% to 26,363.44 - clawed back into positive territory Thursday, with the S&P up 0.12% to 7,732.99 and the Nasdaq up 0.13% to 26,398.17. The VIX, Wall Street's volatility gauge, eased 1.58% to 15.56, suggesting traders aren't especially rattled by the morning's mixed earnings reactions. The divergence reflects a market digesting a dense slate of earnings - some celebrated, some punished - rather than reacting to any single macro shock.

Beat the quarter, miss the future: SanDisk, Western Digital, AppLovin and Datadog all punished on guidance

Four of Thursday's most closely watched earnings reports showed that clearing Wall Street's quarterly bar isn't enough when the outlook disappoints. SanDisk fell as much as 9-10% after issuing third-quarter guidance that fell short of expectations, even though its just-reported results beat estimates - Jefferies cut its price target to $1,750 from $3,000 while keeping a Buy rating. Western Digital dropped 14-15% despite posting quarterly results that topped analyst estimates, as investors focused on a softer outlook instead. AppLovin tumbled 15-19% and Datadog sank 15-20%, both after delivering results that beat Wall Street's numbers but guided investors to expect less growth ahead than hoped. The pattern echoes the AI-capex skepticism that hit AMD and SpaceX a day earlier: investors are increasingly discounting trailing results and pricing stocks off forward guidance alone.

SpaceX steadies as lockup passes, Nvidia gains on exclusive-chip pledge, Alphabet slides on Jeff Dean's exit

SpaceX shares, which sank as much as 13.6% after Wednesday's earnings report revealed capital spending had jumped sixfold to $18.4 billion, rebounded roughly 3-5% Thursday as the company's first post-IPO lockup expired without triggering the feared flood of selling - about 911.5 million insider shares, more than the entire tradable float, became eligible to trade. JPMorgan raised its price target on the stock to $240. Nvidia climbed further, adding to Wednesday's 3.43% gain, after Elon Musk said SpaceX would exclusively use Nvidia processors for its AI computing infrastructure. Alphabet fell about 4% after disclosing that chief scientist Jeff Dean is departing after 27 years at the company as part of a reshuffling of its AI divisions, with DeepMind CEO Demis Hassabis also stepping back from day-to-day operational duties.

Fed credibility questions linger as Warsh's muddled messaging keeps a September hike in play

The bond market is still digesting the fallout from Fed Chair Kevin Warsh's press conference last week, where the Federal Reserve voted 9-3 to hold interest rates steady but Warsh's comments left investors confused about the central bank's actual reaction function. Warsh praised the recent run-up in long-term bond yields as doing some of the Fed's inflation-fighting work for it - remarks investors initially read as dovish, even though a careful reading suggested the opposite. The result, which Bank of America analysts termed a 'central bank inflation credibility shock,' has been a steeper yield curve and rising odds of a September rate hike rather than the hold or cut markets had been pricing. The 10-year Treasury yield has held around 4.60% this week, down from an 18-month high of 4.75% two weeks ago as falling oil prices eased some inflation pressure, but the market's confidence in the Fed's forward guidance itself remains shaken.

Jobless claims hold near historic lows, Challenger layoffs at a two-year low, as Hormuz talks lift gold

Initial jobless claims came in at 199,000 for the week, essentially flat and below the roughly 203,000-204,000 economists expected, extending a stretch of historically low readings that points to a 'low fire, low hire' labor market - companies aren't cutting workers aggressively, but they aren't hiring much either. That theme showed up in Thursday's Challenger report too: U.S. employers announced 33,429 job cuts in July, down 27% from June's 45,849 and the lowest monthly total in two years, ahead of Friday's more comprehensive July jobs report. On the retail side, Costco reported July net sales of $23.12 billion, up 10.7% year-over-year, with comparable sales up 6.6% overall and 18.2% online. Geopolitically, gold pushed above $4,300 an ounce for the first time since mid-June as Iran and Oman edged closer to a deal to partially reopen the Strait of Hormuz, while WTI crude eased to $74.79 a barrel as the same negotiations raised hopes that oil and gas could soon flow more freely through the strait.

Concept of the Day

Forward Guidance

Forward guidance is when a central bank - in the U.S., the Federal Reserve - communicates its intentions for future policy in order to shape market expectations today. Instead of just setting the current interest rate, the Fed uses speeches, press conferences, and statements to signal where rates are likely headed, which lets borrowing costs, stock prices, and bond yields adjust in advance rather than lurching around every time an actual rate decision is announced. Because markets price in expectations, a credible signal about the future is often just as powerful as an actual rate move. The catch is that forward guidance only works if the market trusts it. That's the problem the Fed is grappling with right now: at last week's press conference, Chair Kevin Warsh voted along with the committee to hold rates steady but then praised the recent rise in long-term bond yields as doing some of the Fed's inflation-fighting work for it - a comment markets initially read as dovish, signaling fewer future hikes, even though a more careful reading suggested the opposite. Investors responded by selling long-dated Treasurys and repricing the odds of a September hike higher, the exact opposite of what clear guidance is supposed to produce. Bank of America called it a 'central bank inflation credibility shock.' When forward guidance breaks down, markets lose one of their main tools for pricing risk smoothly, and volatility tends to rise around every subsequent Fed communication until credibility is rebuilt. That's why today's muddled aftermath matters beyond just the bond market: every future Warsh press conference will now be parsed more skeptically, and the yield curve is likely to stay choppier until the Fed re-establishes a clear, consistent signal.

Why it matters

With the 10-year yield swinging on a single confusing press conference and September hike odds now rising rather than falling, forward guidance credibility is directly shaping borrowing costs, equity valuations, and the dollar in real time - not some abstract policy concept. For investors, the lesson is to watch what the Fed's communication actually does to market pricing (yield curve moves, hike-odds repricing) rather than just what officials say, since a Fed chair's words can move markets even before, or instead of, an actual rate decision.

Employment Situation (July jobs report)

Friday's jobs report is the last major data point before the Fed's September decision, especially after today's mixed signals on layoffs and claims.

Wed, Aug 12

CPI (July)

The next inflation reading will show whether falling oil prices are offsetting other price pressures and how much room the Fed has before its September meeting.

Thu, Aug 13

PPI (July)

Producer prices give an early read on pipeline inflation pressures a day after CPI, helping confirm or complicate the inflation picture.

Wed, Aug 19

FOMC Minutes (July 28-29 meeting)

The minutes will show how seriously the committee is weighing a September hike after Warsh's confusing press conference roiled bond markets.
