☕️ [Task Coins Giveaway] Daily Market Talk — Apple Retakes the Crown as Nvidia, SK Hynix Slide

Nvidia's biggest bet is looking shaky. Nvidia (NVDA) sank about 5%, its worst day since February, on fears its reported $250B OpenAI financing guarantee is circular financing in disguise, handing Apple (AAPL) back the crown as the world's most valuable company. Memory chips took the hardest hit of the night, with SK Hynix's (SKHY) new Nasdaq ADR sliding below its own IPO price, while oil crashed about 8.7% on the US-Iran truce. Let's dig in 👇

💬 Is Nvidia's AI spending finally scaring investors, or is this just a healthy pause before the next leg up?

📊 Quick Recap — What Moved & Why

🇺🇸 US — Apple Flips Nvidia, Memory Chips Crack

🔑 Key Event: Monday's cash session looked calm on the surface, with the S&P 500 up 0.02% to 7,413.18, the Dow up 0.51% to 52,210.08 and the Nasdaq Composite off 0.18% to 24,932.08, but underneath it was a brutal day for chips. Nvidia (NVDA) fell about 5%, its steepest drop since February, as investors reassessed the reported $250B financing guarantee it is discussing for OpenAI's Ohio data centre, worried the arrangement amounts to circular financing that flatters both companies' numbers; short-seller Michael Burry reportedly added to his bet against the stock. The drop was enough for Apple (AAPL) to retake the title of world's most valuable company, with AAPL closing around $4.95 trillion in market cap against Nvidia's $4.77 trillion. Memory names took it on the chin too: SK Hynix's (SKHY) new Nasdaq ADR, priced at $149 in a record US listing just three weeks ago, closed around $143, and SanDisk (SNDK) tumbled further, as Western investors fretted over Chinese DRAM oversupply following the blockbuster Shanghai debut of ChangXin Memory (CXMT).

👀 Other to Watch

Palantir (PLTR) +7% → analysts stayed bullish ahead of its August 3 earnings, with Oppenheimer and Citi both reiterating price targets around $200.
SpaceX (SPCX) → closed at a fresh post-IPO low near $113.50, well below its June peak of $225.64.
Nvidia's new "Open Secure AI Alliance" → the chipmaker unveiled a roughly 35-member cybersecurity coalition (Microsoft, SpaceX, Palantir and others), prompted by OpenAI's own AI agent breaching Hugging Face's systems; OpenAI, Anthropic and Google are notably not members.
AstraZeneca (AZN) → kicked off a busy earnings week with core EPS of $2.63 beating estimates and H1 revenue up 9% to $30.7B, even as sales in China fell 13%.
Tesla (TSLA) → its Optimus robot project drew fresh criticism from longtime shareholder Ross Gerber, who said spending toward $1 trillion "to build a robot that folds laundry doesn't make any sense."

🇸🇬 Singapore — MAS Tightens, STI Stays Cautious

🔑 Key Event: Singapore's focus stayed on policy. The STI eased about 0.43% to around 5,595.92 on Tuesday morning, a day after the MAS unexpectedly tightened for a second straight quarter in its Monday statement, nudging up the slope of its S$NEER policy band as core inflation ticked up to 1.6% in June. The sharp drop in oil is a net positive for energy-importing Singapore, even as the local tape stays cautious.

👀 Other to Watch

DBS (D05) · OCBC (O39) · UOB (U11) → the big three sit near record highs heading into Q2 results, due Aug 6 for DBS and Aug 7 for OCBC and UOB.
Macro → MAS's tightening came even as oil crashed, keeping the inflation debate live into the second half.

🇭🇰 HK/China — Chips Buck the US Selloff, CXMT Steals the Show

🔑 Key Event: Hong Kong held onto modest gains Tuesday morning, with the HSI up about 0.98% and the Hang Seng TECH index up about 1.57%, while the HSCEI added around 1.14%. Chip names bucked the overnight US selloff rather than following it lower, a sign the memory-chip scare stayed mostly a US and Korea story for now, especially with mainland media framing the day's biggest chip event, ChangXin Memory's debut, as a domestic positive rather than a global oversupply risk.

👀 Other to Watch

ChangXin Memory (CXMT) → surged 465.82% on its Shanghai STAR Market debut, its roughly ¥3.28 trillion market cap briefly overtaking ICBC as China's largest listed company, with turnover of about ¥1.41 trillion becoming the first single-day total above ¥100B for any A-share stock; Chinese financial media framed it as validating the domestic DRAM supply chain rather than the oversupply threat Western coverage tied to SK Hynix and SanDisk.
Zhongji Innolight (300308.SZ) → priced its Hong Kong listing at HK$980 a share, a roughly 21% discount to its Shenzhen-listed A-shares, raising about HK$53.4B (~US$6.8B) from 33 cornerstone investors including Temasek, Hillhouse and BlackRock who together took about US$3.45B; retail margin financing was reportedly oversubscribed around 12 times ahead of Thursday's debut, the city's largest listing since Alibaba's 2019 secondary offering.
Baidu (9888.HK / BIDU) → pressing ahead with converting its Hong Kong listing from secondary to dual-primary status, after its board approved the move on July 16 and HKEX acknowledged the application on July 22; no effective date is set yet, though the market is watching for it to land in time for the September Stock Connect review.
Aviation, PCB & AI-application stocks → these groups, not the big internet platforms, led Tuesday morning's actual gains, a narrower rally than a broad "China tech" story would suggest.

🌍 Other

Oil → Brent crashed about 8.7% to $88.36 and WTI fell about 7.5% to $82.61, after the US and Iran held a weekend pause in strikes, unwinding the war-risk premium that had lifted crude above $100 last week.
Fed → the FOMC meets Tuesday and Wednesday US time, with a decision landing around 2am SGT Thursday; the meeting is unusually hard to call, with the current 3.50-3.75% range seen as a genuine coin flip between a hold and a hike as sitting Chair Kevin Warsh weighs still-elevated inflation, even as President Trump keeps pushing publicly for lower rates.
US-China AI tensions → US officials reportedly threatened sanctions and a possible Entity List listing against Chinese AI firm Moonshot AI, accusing it of distilling a US model into its Kimi K3 system; China's Commerce Ministry called the threat "typical AI hegemonism" that "lacks factual and legal basis," without naming Moonshot directly, and vowed countermeasures if China's interests are harmed.
