US Pre-Market: Crypto, Optical Module and Memory Stocks Mostly Higher

The synchronized move across crypto, optical module and memory names suggests a broader risk-on bid in pre-market rather than anything company-specific, since no single catalyst ties these sectors together. Crypto-adjacent equities remain the most sentiment-driven of the group, so their gains are a useful read on appetite for higher-beta exposure. The open question is whether this breadth holds into the regular session or fades, given pre-market moves often reflect thin liquidity.
