Definition
Prices ending in lots of zeros, like $4,000 gold or 7,500 on the S&P 500 (example numbers), which tend to get extra attention from traders and the media.
The story
There's nothing mathematically special about $4,000, but headlines treat it as a milestone and some traders place orders around it. In October 2026, Reuters wrote that gold's drop was "asking serious questions of technical support around the $4,000 level."
Why you'll see it
Round numbers become levels partly because so many people are watching them.
