对GDP修正和市场反应感到困惑

Often, the 'surprise' element is already diminished by earlier data points that hint at the revision. Markets tend to price in expectations, so if a revision aligns with what other indicators were suggesting, the impact is less dramatic. It's about the delta between expectation and reality.

ส่วนหนึ่งอาจเป็นเพราะตลาดรับรู้ข้อมูลล่วงหน้าไปแล้วครับ หรือบางที revision ก็ไม่ได้เปลี่ยนภาพรวมของเศรษฐกิจมากพอที่จะสร้าง impact ใหม่ ๆ ให้กับตลาด

It's often about what's already priced in. If the revision was largely anticipated or if other, more forward-looking indicators are painting a different picture, the market might just yawn. The initial reaction to the advanced estimate often takes the lion's share of the move.

That's a really good point. I've noticed that too and wondered if it's because the 'advance' number already sets the tone, and later revisions are just confirmations that don't surprise as much? Or maybe it's just one piece of a bigger puzzle that gets overshadowed.
