Market Prism classifies VALE as an Exhausted Narrative — the story that powered the move has burned through most of its attention and momentum. Narrative energy has declined to 22%, suggesting the thesis is losing traction.

Key risks & what happens next

When a narrative exhausts, the marginal buyer disappears. Price tends to drift lower or stall until a genuinely new catalyst resets the story. The 70.1% fundamental-value deviation is extreme and, historically, tends to revert within 30–60 trading days.
