10-22 01:30	Kalshi	其他	FUN FACT: Micron has increased the amount of DRAM produced per wafer by about 400x over the past 30 years X 上的 @Kalshi ↗
10-18 00:45	Arcus	其他	This weekend, memory stocks swept ~7% in minutes on perp markets, on no news, then bounced most of the way back. On Arcus, price bands held the move. Outside regular trading hours, perps trading and the mark price are constrained to a range around the last regular-hours price. The range widens only if sustained pressure builds - so a flash wick in thin weekend liquidity can't instantly mark positions down. The result on Saturday: 44.4k orders were rejected at the band floor, and 98% of open positions on SKHY, SNDK, MU, DRAM, CRWV, and BE made it through the wick without being liquidated. Price bands don't make liquidation impossible - a real, sustained move will still move the mark. They exist so you aren't liquidated by ten minutes of thin liquidity.

10-16 15:31	Vest Markets	其他	US-listed memory shares are extending a week-long selloff, with $SKHY down around 5% on the session. Over $700 billion in global memory-chip market value has been erased since October 10, when China's CXMT detailed a denser 4F2 DRAM design. Goldman flagged $SKHY and Samsung today as attractive risk/reward, arguing the market overestimated China's tech gap. X 上的 @VestExchange ↗

10-12 15:30	Vest Markets	其他	Memory names are under pressure on the session, with $MU down around 4% and $SNDK down around 6.5%. Chinese DRAM maker CXMT said over the weekend it made key progress on a denser 4F² cell design, with a DDR5 server product planned by end-2026. Trade $MU, $SNDK and broader memory volatility with a Vest Capital funded account and access up to $25k in trading capital. X 上的 @VestExchange ↗
