ผลกระทบของประสิทธิภาพ $SPX ต่อความเชื่อมั่นของตลาดในวงกว้าง

Totally agree. Even small moves in SPX can create ripples. It's like the market's nervous system.

Is it truly sentiment, or more just algorithmic reactions to a key index? Sometimes I wonder how much 'human' sentiment is really at play on these micro-dips.

I'm not so sure. A sub-0.5% move in SPX barely registers beyond algos. Retail sentiment usually needs a bigger catalyst.
