On-chain Korean stocks begin to guide US stocks | TradeXYZ Weekend Market Watch

After chasing the main line of the US-Iran situation for more than two months, it has rarely gone quiet this weekend. No new attacks, no new threats. Geopolitical news flow has entered a low-intensity stalemate.

The crude oil trend reflected this quiet. Over the weekend, both WTI crude oil futures and Brent crude oil futures oscillated back and forth within a narrow range of ±0.6%, with volatility falling to the lowest level since the conflict erupted. Before futures opened, CL was reported at −0.09% and Brent crude oil at −0.20%; after opening, they edged lower to CL −0.40% (68.55) and Brent −0.44% (71.85), almost as if "nothing happened."

But nothing ever really happens in the market—when the macro main line fades, the driving force of the market shifts to structure. Over this weekend, the structural protagonist was the memory sector; and due to the U.S. market being closed on Friday for the Independence Day holiday, Friday's spot trading session in South Korea became the only active pricing signal source on TradeXYZ over the weekend.

Individual Stocks

On the last trading day of last week (Thursday) for U.S. stocks, the memory sector continued its decline. But the wind turned sharply on Friday—the U.S. market was closed for Independence Day, while the South Korean market had an explosive day: SK Hynix surged as much as 10.9% intraday, and Samsung closed up 8.2%.

Since the U.S. spot market was closed, this signal could only be transmitted through TradeXYZ's weekend order book. MU, SNDK, and other memory stocks followed the Korean stocks, rising about 5%: MU +5.48% (1,031.70), SNDK +3.96% (1,832.90), DRAM spot +6.56% (65.19).

Looking across the entire weekend, the gains in the memory chain further expanded: DRAM +9.13%, SNDK +7.52%, MU +6.43%, WDC +5.6%, with periphery names like ARM +3.5%, MRVL +3.8%, and LITE +4.0% also strengthening in sync. A complete "memory super cycle" trade self-reinforced in a vacuum with no macro interference.

However, there was turbulence this morning. After the Asian open, Korean stocks fell first then rose. SK Hynix initially plunged sharply, then recovered significantly; Samsung was up slightly at 1.03%. Meanwhile, MU and SNDK on TradeXYZ almost exactly replicated SK Hynix's asymmetric V-shaped pattern minute by minute.

During the vacuum period of the U.S. market closure, memory sector U.S. stocks on TradeXYZ have fully treated Korean stocks as the real-time pricing anchor.

With BTC's rebound, crypto-related stocks continued their uptrend.

Commodity Futures

Natural gas was the only commodity futures with a clear narrative, falling 2% after futures opened. Previously, natural gas prices were supported by air conditioning electricity and gas-fired power generation demand from the heat wave in the central and eastern U.S., but the latest forecasts indicate this heat wave is about to exit. The Commodity Weather Group expects that from July 7 to July 16, the eastern two-thirds of the U.S. will see temperatures return to near seasonal normal levels, cooling degree days will decline, and expectations for gas-fired power generation demand will follow suit; the U.S. National Weather Service also expects the heat wave in the east and Midwest to gradually ease early this week.

Precious metals went through a small "surge then retreat" script. Gold, silver, and copper futures initially rallied after opening, then gave back all gains: gold closed at −0.54% (4,155.10), silver at −0.90% (61.85), and copper pulled back in tandem.
