Jensen Huang said on Monday that he is not afraid of custom chips. The same day, Nvidia put US$3.5 billion into MediaTek convertible bonds and brought MediaTek onto its own NVLink. He is not trying to keep custom chips outside the door; he wants them running across Nvidia's network. Reports say the tie-up is meant to get custom data-centre chips deployed faster. Nvidia closed 1.48 per cent higher at US$220.78. On the custom-silicon side, the tape read the opposite way. $Marvell Technology(MRVL)$ fell another 2.29 per cent to US$211.66, and its gain for the year slipped from 154.91 per cent on Friday to 149.07 per cent. The wound is the same one as last week. Revenue from the US$120 billion arrangement with

On Wednesday $S&P 500(.SPX)$ closed 0.48 per cent lower, its third session in a row heading down. $Meta Platforms, Inc.(META)$ rose 6.55 per cent the same day to close at US$653.69. The whole market was backing away while one of the largest companies in it put on six and a half points, and those look like two unrelated things. They are one thing. What is holding the indexes down is rates: Brent crude moved back above US$100 for the first time in two months, the inflation print lands on Friday, the ten-year Treasury yield was pushed to 4.85 per cent and the thirty-year broke above 5.30 per cent. The Treasury stepped in that day and raised the cap on its buybacks of ten-

One batch of results, three different share prices. $Dell Technologies Inc.(DELL)$ closed 15.81 per cent higher on Wednesday at US$492.20. Credo's revenue more than doubled from the previous quarter and the stock closed down 20.04 per cent at US$165.22. $Broadcom(AVGO)$ left its answer until after the close, beat on both revenue and earnings, and saw its shares push above US$370 before being knocked back below US$350. The hardest number in Dell's results is US$95 billion — a record order backlog for AI servers. It raised full-year revenue guidance by US$25 billion to US$192 billion at the same time. At least 15 firms moved their targets that day: UBS from US$455 to US$500,

The indices: Dow up, Nasdaq flat, a split that maps onto earnings week The three indices diverged on Tuesday: the $Dow Jones(.DJI)$ rose 1.02 per cent to 52,495.88; the $S&P 500(.SPX)$ rose 0.28 per cent to 7,712.57; the $NASDAQ(.IXIC)$ was nearly unchanged, closing down 0.02 per cent at 26,424.82. The 10-year Treasury yield settled at 5.12 per cent. The Dow–Nasdaq split tracks the shape of this week's reporting calendar: technology names started spreading risk before the numbers are in, some moving forward, some pulling back. Memory: the CXMT overhang still has not cleared

The market: Amazon led as QQQ rebounded faster than SPY $Invesco QQQ(QQQ)$ rose 1.21 per cent to US$718.36 on Monday, $SPDR S&P 500 ETF Trust(SPY)$ gained 0.42 per cent to US$766.48, and the $S&P 500(.SPX)$ added 0.41 per cent to 7,690.73. Amazon rose 4.98 per cent, lifting technology and the data-centre supply chain and giving the Nasdaq-100 its best performance in almost a month. The advance went beyond one large-cap rebound. Money spread from Amazon into memory, semiconductors and networking equipment, showing that Friday's selling had cooled. The questions around rates and investment returns remain. Result

All three indexes closed lower on Tuesday, the Dow worst of them at 1.18 per cent, $S&P 500(.SPX)$ down 0.58 per cent and $NASDAQ(.IXIC)$ Composite down 0.32 per cent. Chips went the other way on the same day: Intel put on 9.05 per cent to close at US$104.47, back above US$100 and the biggest gain in the row. The indexes went one way and the chips went the other, and that is the split this day comes down to. What pushed the indexes down was oil. WTI moved above US$94 and Brent came close to US$99, and what pushed oil up were attacks in the Middle East. The attacks fell over the weekend, so they were not in Friday's closing prices and only arrived at Tuesday's open. The

The market: QQQ and SPY fell as Warsh gave no answer on October rates $Invesco QQQ(QQQ)$ fell 2.50 per cent to US$709.80 on Friday and $SPDR S&P 500 ETF Trust(SPY)$ fell 1.11 per cent to US$763.25. Headline CPI was 3.7 per cent from a year earlier in September, above the market's 3.6 per cent expectation and the prior 3.4 per cent reading. PPI reached 6.3 per cent, above the 5.5 per cent expected and the revised prior 5.6 per cent. Consecutive upside inflation surprises forced highly valued technology to absorb the rate repricing first. Fed chair Kevin Warsh did not prejudge the meeting on 27–28 October. He reiterated the commitment to price stability while describing AI

The indices: the Nasdaq set a record close, the Dow did not follow The three indices pulled apart on Monday: the $NASDAQ(.IXIC)$ Composite rose 1.05 per cent to 27,477.31, a record close for it, having reached 27,544.06 at its intraday peak; the $S&P 500(.SPX)$ rose 0.66 per cent to 7,773.95, still shy of its own record close by less than 0.6 per cent; and the $Dow Jones(.DJI)$ Industrial Average added just 0.18 per cent to 51,267.90. The 10-year Treasury yield closed at 5.31 per cent, three basis points above Friday. Put those three together and what made the high was not the breadth of the market but a handfu

Hello. The Treasury's buyback tool was upsized again, and the bond market bought it for half a day. US Treasury Secretary Bessent said on Thursday that the size of each long-dated Treasury buyback had gone from US$2 billion to at least US$4 billion, and could rise further. The 30-year yield fell as much as 10 basis points and the dollar index weakened — and then the bond market pushed back. The reason is simple enough: buybacks deal with liquidity, while the deficit, inflation and the term premium have not moved at all. There was a new variable that day: the consumer. $S&P 500(.SPX)$ closed down 0.87 per cent and $Dow Jones(.DJI)$ 1.32 per cent, about 600 points — Barro

Hello. The largest first tranche of any IPO lock-up in US market history came free last night: 911.5 million $SpaceX(SPCX)$ insider shares became eligible to sell, taking the freely tradable count from about 639 million to roughly 1.55 billion in one step. The shares rose 6.14 per cent. The day the selling actually happened wasn't last night. It was the day before. On Wednesday the stock fell 13.61 per cent on about 200 million shares, the heaviest turnover since 18 June; last night volume hit 251 million and set another high, yet the price went up. Heavier volume than Wednesday, and the price went the other way — the people who wanted to sell had mostly finished on Wednesday. Someone went back through three comparable cases: in ea
