A weekly intelligence brief
Stocks and Markets Desk · Weekly Dispatch
Oil spiked and a sharp global rotation out of chip stocks hit Wall Street, Tokyo and Shanghai on the same Friday, after the United States struck Iranian military assets following attacks on three tankers in the Strait of Hormuz, and after TSMC paired a record profit with a much larger AI spending plan that spooked investors. The S&P 500 fell for the week even as Thailand, Argentina and Hong Kong kept climbing.
Weekly Brief | Analyst Desk | 17 July 2026
Two shocks hit markets this week, and neither one alone explains Friday's selloff. The first came from the Strait of Hormuz: the United States struck Iranian coastal and military assets after attacks on three commercial vessels, and President Trump declared the ceasefire over. Brent crude, the international oil benchmark, jumped as much as 5.4 percent on the initial spike, pulled back to 76.30 dollars a barrel by midweek as traders bet on a return to talks, then rose again after a fresh round of attacks on Monday 13 July. By the 16 July close, Brent stood at 84.63 dollars a barrel, up 8.15 percent over the past month. The safety trade that follows oil scares, money moving toward government bonds and defensive shares, extended through the week.
The second shock was homegrown. TSMC, the world's largest contract chipmaker, reported a record quarterly profit of about 22 billion dollars on 16 July, but paired it with a much larger 2026 spending plan, 60 to 64 billion dollars, up from an earlier 52 to 56 billion. Investors read the increase as a sign that the AI buildout needs ever more capital for returns that have not yet shown up, and combined with fresh competition to Nvidia from custom AI chips built through an 8 July OpenAI-Cerebras partnership and by Amazon's own chip program, that worry tipped into a global selloff. The Nikkei, the CSI 300 and the Nasdaq each had their worst single day of the week on Friday 17 July.
A rotation out of semiconductors and into steadier sectors was already under way a week ago; this week's news accelerated that shift rather than reversing it. Healthcare and energy shares gained while chip names, including some of this year's biggest winners, gave back ground fast. The loudest number of the week, TSMC's record profit, and the number that actually moved markets, its capital spending raise, pointed in opposite directions.
This brief walks through the United States, Europe (including Prague), Asia (China, Japan, Hong Kong and Thailand), the wider emerging markets (including Argentina), and Russia and Israel. For each market it gives the index level, the date that level applies to, how far it has moved and against what earlier point, and what the numbers mean in plain terms: what a record looks like, what a price-to-earnings ratio implies about how many years of earnings an investor is paying for up front, and what a given VIX reading signals about fear. Every figure carries a source, and where a number could not be confirmed as current for this week, that is flagged rather than presented as live.
| Market | Where it stands right now |
|---|---|
| US: S&P 500 and Nasdaq | S&P 500 at 7,472 intraday on 17 July, down 1.36 percent for the week from the 10 July close of 7,575. Nasdaq at 25,882 on the 16 July close, down at least 1.24 percent for the week before Friday's chip-led losses were even added in. The VIX (fear gauge) near 18 on 17 July, up about 20 percent for the week but still inside the 12 to 20 band that counts as calm to normal. |
| Europe | Stoxx 600 at 641 on 17 July, essentially flat for the week (up 0.04 percent from the 10 July close). Prague's PX at 2,583 on 17 July, up 0.04 percent on the day; its price index is down 3.84 percent for the year even though a total-return version that counts dividends is up 0.23 percent, and it now sits well off the roughly 2,700 to 2,805 highs reported earlier in 2026. |
| Asia | Japan's Nikkei fell to 64,004 on 17 July, down 6.64 percent for the week, the sharpest weekly move in this brief. China's CSI 300 dropped to 4,531 intraday on 17 July, a three-month low, on chip-sector IPO jitters. Thailand's SET held at 1,638 on 17 July, up 0.18 percent on the day and roughly 30 percent for the year. |
| Emerging Markets | MSCI Emerging Markets near 1,621 around midweek, down about 2.58 percent from its prior reading. Argentina's Merval closed 16 July up 1.92 percent on the day and 57.12 percent for the year. Emerging-market ETFs took in a record 38 billion dollars in the first half of 2026, even as the latest weekly count showed a 10th straight week of net outflows. |
| Russia and Israel | Russia's MOEX at 2,035 on 17 July, up 0.64 percent on the day but down 26.31 percent over the past year, after 17 straight weeks of declines through late June, the longest losing streak since 1997. Israel's TA-35 at 4,117 on 17 July, down 0.94 percent on the day and about 11 percent below its 6 May record of 4,629. |
Levels as of 16 to 17 July 2026 unless noted. Index levels move constantly; treat these as snapshots. Each market is explained below.
The S&P 500, the index of 500 large US companies, traded at 7,472.36 intraday on 17 July, down 38.63 points on the day and down 1.36 percent for the week from the 10 July close of 7,575.39. The Nasdaq Composite, heavy with technology shares, closed 16 July at 25,881.95, down 1.47 percent on the day and down at least 1.24 percent for the week through Thursday; Friday's futures fell further on the chip selloff, so the full week's loss was likely deeper still. The S&P 500's forward price-to-earnings ratio, the price divided by the earnings companies are expected to report over the next year, sat in the 20.4 to 21.3 range depending on the source and exact date in July (not independently confirmed for 17 July itself). A forward P/E near 21 means an investor buying the index today is effectively paying about 21 years of the market's current annual profit rate up front, not literally, since earnings should keep growing, but as a rough gauge of how much optimism is priced in, and it is on the expensive side of the market's long-run average.
The VIX, an index that measures how much turbulence investors expect in US shares over the next month and is often called the fear gauge, traded near 17.96 to 18.01 intraday on 17 July after closing 16 July at 16.73, up 6.76 percent on the day, a rise of roughly 20 percent for the week from the 10 July close of 15.03. In plain terms, a VIX below 20 is a calm to normal reading, and this week's level, even after the jump, stayed inside that band. Genuine panic tends to show up above 30, so options markets were pricing rising unease, not crisis, even with Iranian strikes and a global chip selloff landing in the same week. The 10-year Treasury yield, the interest rate on 10-year US government debt that anchors borrowing costs worldwide, held close to flat at 4.54 percent on 17 July versus 4.56 percent on 10 July, though it touched a near two-month high of 4.62 percent on 13 July before easing back. A week this volatile in oil and equities produced no clean flight into bonds, a sign investors had not settled on which risk to hedge against.
The Nasdaq 100's forward price-to-earnings ratio sat near 23.2 times expected earnings, down from 27.4 times on 1 January 2026. A falling multiple even as the AI story keeps running means the market is paying less per dollar of expected future profit than it was at the start of the year, consistent with growing caution about how much AI spending will actually earn back. That caution runs through the whole week: the chip names that pulled the Nasdaq's multiple down in the first half of the year did so again on Friday, when the sector-wide selloff triggered by TSMC's spending guidance hit hardest.
The Stoxx 600, the broad index of European shares, closed at 641.34, down 0.37 percent between the 16 and 17 July sessions, after a 16 July close of 643.72 (up 0.16 percent on the day). Measured against the 10 July close of 641.10, the Stoxx 600 is essentially flat for the week, up just 0.04 percent. One figure found in this week's research put the weekly move at down 1.30 percent; that conflicts with the two dated closes used here and looks like a stale comparison window, so it is set aside in favor of the flat reading, which should still be treated as needing a cleaner check next week.
The Prague Stock Exchange's PX index closed at 2,582.52 on 17 July, up 0.04 percent on the day (a same-day snapshot at 09:17 showed 2,584.70, and the 13 July close was 2,588.06). The PX price index is down 3.84 percent for the year to date, a real reversal after Prague's index was reported earlier in 2026 near all-time highs around 2,700 to 2,805. Investors who also count dividends see a different picture: the PX total-return index, which adds dividend payouts back into the return, is up 0.23 percent for the year. That gap, a falling price index but a positive total-return index, is a reminder that a quoted index level alone does not capture what shareholders actually earned; dividends can turn a losing price chart into a small gain.
Europe imports most of its oil, so this week's Brent crude move, a spike toward 84.63 dollars a barrel on 16 July after a midweek pullback to 76.30 dollars, is a straightforward cost headwind for the wider Stoxx 600, even for a bank-heavy market like Prague that carries less direct fuel exposure.
Japan's Nikkei 225 fell to 64,004.00 on Friday 17 July, down 4.03 percent on the day and down 6.64 percent for the week from the 10 July close of 68,557.73 (itself up 1.20 percent on the day). That is the largest single weekly move of any index in this brief, a direct result of how heavily Japanese markets are weighted toward semiconductor equipment makers that supply the chip industry now in retreat. The Nikkei's forward price-to-earnings ratio of about 16.87 times is a 1 January 2026 baseline with no live July reading available, so it carries low confidence as a current valuation guide.
China's CSI 300, the index of the largest mainland shares, fell to 4,531 intraday on Friday 17 July, down 3.55 percent on the day and a three-month low, after a 16 July close of 4,698.43 (down 1.85 percent). The index was headed for its biggest weekly drop in two and a half years. The trigger was a familiar one this month: CXMT, a Chinese memory-chip maker, priced an 8.6 billion dollar initial public offering, and the wave of large AI-linked listings it belongs to stirred fears that too much cash was being pulled out of existing shares to fund new ones. The CSI Semiconductor Index had already plunged 9.4 percent in an earlier July session, its biggest one-day drop in about four years, following a roughly 110 percent gain since the start of the year. Read together, this looks like profit-taking after an extraordinary run rather than a break in China's underlying growth story; the CSI 300's trailing price-to-earnings ratio, a backward-looking measure using the past year's actual profits rather than forecasts, stood at 14.8 times as of June 2026, and no live forward figure could be confirmed.
Hong Kong's Hang Seng closed at 24,488.00 on 17 July, down 2.08 percent on the day, after a 16 July close of 25,009 (up 1.3 percent on soft US producer-price data). Measured against the 10 July close of 24,175.12, the Hang Seng is still up 1.29 percent for the week: Friday's rout took back some of an earlier rally but did not erase it. Thailand's SET index closed at 1,638.20 on 17 July, up 0.18 percent on the day, extending a run that took it up 26.3 percent in the first half of the year and roughly 30 percent for the year to date on a self-computed estimate. The SET's forward price-to-earnings ratio of about 16.1 times at the end of June ran ahead of a roughly 13.2 times average across Asian markets, and even excluding the outsized weighting of Delta Electronics it was still 13.1 times, meaning Thai shares carry a premium valuation for the region even after a strong run.
The MSCI Emerging Markets index traded near 1,621.09, down about 2.58 percent from its prior reading around midweek (the timestamp on this figure is ambiguous and is treated here as 16 to 17 July). Its forward price-to-earnings ratio of about 13.44 times is a year-end-2025 baseline that has not been verified as current for July, so it carries low confidence. The more telling numbers this week are about flows rather than prices: emerging-market exchange traded funds took in a record 38 billion dollars in the first half of 2026, beating the previous full-year record of 35 billion dollars set in 2025, yet the latest weekly reading, for the week ending 1 July, showed a 10th consecutive week of net outflows, about 5.14 billion dollars. Read together, that combination looks like short-term profit-taking layered on top of a structurally strong year for money going into developing-market shares, not a reversal of the broader trend.
Argentina's Merval index closed 16 July at 3,291,246 points, up 1.92 percent on the day and up 57.12 percent for the year to date, with financial shares leading what has become a market-wide bet on President Milei's economic reforms. The peso held roughly stable around 1,475 to 1,476 to the dollar. YPF, the state-controlled oil major and a large weighting in the index, closed 16 July at 48.45 dollars, down 3.60 percent on the day (a small number of lower-confidence snippets cited a higher 49.50 to 50.44 dollar range, but the 48.45 dollar figure comes from a direct exchange fetch and is used here). YPF's 52-week range runs from 22.82 to 57.49 dollars, and its forward price-to-earnings ratio of roughly 7.7 to 8.1 times, a January 2026 figure with medium confidence, sits well below its own five-year median of 10.8 times, meaning the shares are priced cheaper relative to expected earnings than their own recent history.
Russia's MOEX index closed at 2,034.83 on 17 July, up 0.64 percent on the day, a small bounce inside a much larger slide: the index is down 18.12 percent over the past month and down 26.31 percent over the past year. As of late June, MOEX had fallen for 17 straight weeks, the longest unbroken losing streak since 1997, and the index sits back near the lows first hit on the day Russia invaded Ukraine in February 2022. The drivers line up together rather than pointing in different directions: a smaller than expected interest-rate cut from the central bank, falling oil prices for much of the stretch, a rouble strong enough to squeeze the dollar value of exporters' overseas earnings, fuel shortages inside Russia from Ukrainian strikes on refineries, and the standing risk of further sanctions.
Israel's TA-35 index closed at 4,117.45 on 17 July, down 0.94 percent on the day and down 3.13 percent for the week (the exact date range behind that weekly figure is not fully clear, so treat it as a medium-confidence estimate). The index remains about 11 percent below the all-time high of 4,628.97 it set on 6 May 2026, and it fell more than 12 percent in dollar terms in June alone, as progress in Iran peace talks raised a specific fear for Israeli investors: that a negotiated settlement could leave Israel in a weaker position than continued military pressure would. Israel has since signaled scepticism toward the terms of the US-brokered ceasefire and has reserved the right to strike independently, which helps explain why this week's escalation, alarming as it is, has not been purely negative for a market that had already been pricing in exactly this kind of unresolved conflict.
The VanEck Semiconductor ETF (SOXX), a fund that tracks major chip companies, fell 5.1 percent in a single session this week. Across the month, AI-linked chip stocks lost more than 1 trillion dollars of combined market value, not from one bad earnings report but from a combination of TSMC's higher spending guidance and fresh competition to Nvidia's dominant position: an OpenAI partnership with chipmaker Cerebras announced 8 July, and Amazon's own push to build its own AI accelerator chips rather than buy Nvidia's. One Bernstein Research estimate, found through search and not independently confirmed here, put Nvidia's share of the China AI chip market cratering from 66 percent in 2024 to just 8 percent this year as Huawei and China's SMIC scale up domestic alternatives; treat that figure as directional rather than confirmed.
On the other side of the rotation, healthcare shares (tracked by the XLV fund) gained 2.22 percent and energy shares (XLE) gained 0.92 percent, both aggregator-sourced, medium-confidence figures. Healthcare is a classic defensive sector, one investors buy when they want steadier, less economically sensitive earnings; energy's gain lines up directly with the week's oil spike. Market breadth, meaning how many individual stocks rose versus fell, reportedly held up even as headline indexes fell, the clearest evidence that this was money moving between sectors rather than an exit from equities altogether.
JPMorgan, Goldman Sachs, Citi, Bank of America and Wells Fargo reported second-quarter results on 14 July, with Morgan Stanley following on 15 July. Results were strong, helped by underwriting fees from the SpaceX initial public offering and by a jump in trading volumes tied to the Iran conflict's volatility; a direct fetch of the detailed numbers was not available this week, so this reading carries medium confidence.
TSMC, the Taiwanese company that manufactures chips for Nvidia, Apple and most of the rest of the industry, reported on 16 July: a record quarterly profit of about 22 billion dollars, a gross profit margin of 67.7 percent that beat its own guidance, and 2026 capital spending guidance, the money a company commits to build new plants and equipment, raised to 60 to 64 billion dollars from an earlier 52 to 56 billion dollars, alongside a lifted revenue-growth forecast of more than 40 percent for the year. Every one of those numbers was good news taken alone. Together, the spending increase read as a signal that the AI buildout will keep consuming enormous capital before it produces matching profit, and it was that reading, more than the earnings themselves, that triggered Friday's global chip selloff.
SK Hynix's 10 July Nasdaq listing raised 26.5 billion dollars (177.9 million shares priced at 149 dollars each), the largest listing by a non-US company in US market history, beating Alibaba's 25 billion dollar record from 2014 (a separate, lower-confidence figure of 28.1 billion dollars appeared in one snippet; the 26.5 billion dollar figure is corroborated by two independent sources and is used here). The stock popped 13 percent on its first day to 168.01 dollars, then gave that back fast: down 6 percent on Monday 13 July and down another 14 percent in Thursday 16 July's TSMC-driven selloff. SpaceX shows a starker version of the same pattern. It is not a new listing, having gone public 12 June at 135 dollars a share in an offering that raised about 86 billion dollars and briefly pushed the stock above 200 dollars, but it closed at 135.27 dollars on 15 July, essentially erasing its entire post-IPO gain after losing value in nearly every week since its peak.
CXMT, the memory-chip maker whose 8.6 billion dollar IPO helped trigger this week's China selloff, priced its listing during the week. ASML, the Dutch maker of the machines that print chip circuits, reported earnings on 15 July. Netflix was reported, in headline coverage only and with lower confidence, to have fallen after its own results.
This week's flows fit a simple pattern once the pieces are laid side by side. Oil-linked and defensive shares (energy, healthcare) gained while a single crowded trade, AI-linked semiconductors, lost more than 1 trillion dollars of combined value across the month. Government bond yields, which usually fall hard when investors want safety, stayed closer to flat: the 10-year Treasury touched a near two-month high of 4.62 percent on 13 July before easing back to 4.54 percent, suggesting the bond market has not fully decided the Iran conflict is the dominant risk over the chip rotation.
The clearest flow story of the week sits inside emerging markets themselves. A 10th straight week of net ETF outflows (about 5.14 billion dollars for the week ending 1 July) coexists with a record 38 billion dollars of inflows across the first half of 2026 as a whole, and with Thailand alone drawing 41 billion baht of net foreign buying as of 7 July, up from 27 billion baht at the end of June. The short-term outflow looks like profit-taking inside a longer, structurally positive year, not a reversal of the broader allocation trend into developing-market shares.
Strict pattern recognition, not prediction. Saturn and Neptune remain together in early Aries this week, barely moved from a week ago, a signature this brief has read as structures under strain meeting fog and false calm; that fits a week where a real military strike briefly moved oil and then the market shrugged, while the far larger move, more than a trillion dollars erased from chip stocks, built quietly underneath. Jupiter in Leo, a placement associated with spectacle, again produced the loudest number of the week, TSMC's record 22 billion dollar profit, even as the detail buried inside that same report, the capex raise, did the actual work of moving markets. The pattern worth holding onto: the biggest headline and the biggest mover were, once again, two different things.
Oil drifts back down from the mid-80s toward the low 70s as the ceasefire, however distrusted, holds without further strikes; the dollar and bond yields settle; and chip shares, after a month that has already erased more than a trillion dollars of value, find buyers among investors who see this as an overdue reset rather than the end of the AI story. In that world the S&P 500 recovers toward its 10 July level, Hong Kong's and Thailand's gains hold, and Israel's market, which has been pricing exactly this kind of resolution, likely re-rates higher.
A further attack in the Strait of Hormuz pushes Brent back above 87 dollars and toward the round number of 100; the Fed, already facing a hawkish backdrop, leans against near-term rate cuts; and the chip rotation, instead of settling, spreads into the broader Nasdaq as investors question AI spending across the board rather than at TSMC alone. Markets already down for the week, Japan and China chief among them, would have the least room to absorb a second shock, and fuel-importing markets across Europe and Asia would feel it first.
