    A turbulent month of July (opens the original)

    Excerpt · Critical tone

    Read excerpt

    Key TakeawaysThe headline numbers looked calm. Underneath, it was anything but.The S&P 500 gained 0.7% and the Nasdaq climbed 1% on the day, leaving the month roughly flat overall but that flatness hid some real sparks of volatility. Small-caps and transports both dropped about 3% for the month, the VIX spiked to its highest level since April, and semiconductors got hammered (-20% MTD, the worst month since October 2008) even as hyperscalers like Microsoft had their best month since 2007.

    The real-asset rotation: why capital is moving from AI’s brain to its body (opens the original)

    Excerpt · Neutral tone

    Read excerpt

    The market is in the early stages of a rotation away from concentrated bets on AI’s “digital brain” — the chipmakers and hyperscalers that have driven returns for years — and toward the physical, real-asset infrastructure needed to actually deploy that intelligence in the world. This isn’t a rejection of the AI trade; it’s a broadening of it, driven by a simple math problem (extreme concentration risk), a real market signal (semiconductors in a bear market), and a growing recognition that turnin

    Semiconductors fall into bear market territory (opens the original)

    Excerpt · Critical tone

    Read excerpt

    Wall Street closed out a rough week on Friday, with the S&P 500 down about 1%, the Nasdaq 100 off roughly 1.4%, and the Dow the relative outperformer at down 0.8%. The real damage was concentrated in chips: the Philadelphia Semiconductor Index sold off hard into the close, finishing down 1.6% on the day and, in the process, officially crossing into bear-market territory — down some 20% from its peak. Nvidia alone was the single biggest drag on the index, and breadth was ugly across the board, wi

    Semiconductor chip rotation exacerbates (opens the original)

    Excerpt

    Read excerpt

    Chips are once again the market’s weak link, and Thursday’s session made that plain even as the broader tape looked deceptively calm. The S&P 500 slid roughly 0.5% into the close, and the Nasdaq fell about 1.5%, but the damage was narrow: nearly 370 S&P constituents actually finished higher, with the losses concentrated almost entirely in a handful of semiconductor names.

    Semiconductors' pricing momentum rollover (opens the original)

    Excerpt

    Read excerpt

    Wall Street spent Wednesday chopping sideways in a session that, on the surface, looked almost sleepy — the Dow added just 81 points, the S&P 500 notched up, and the Nasdaq flipped from red to a 0.6% gain by the close. But underneath the placid index-level moves, a much sharper rotation was playing out, and the fault line ran straight through the semiconductor sector. Micron , Lumentum , SanDisk and Western Digital were all dow
