Cosan rallies 10% as an early-exit warning hits the fresh sell signal

August 21, 2026

Our view last week

Cosan drops 9.8% this week as buyer dominance collapses: sellers are extremely dominant on the last bar. On the daily chart price prints a rejection hammer, but the weekly picture stays bearish, with IQS at 66 and signal strength at its max: the decline is making lower lows, with no sign of exhaustion. After weeks of a fading buy signal, a fresh sell signal now kicks in this week.

This week's summary

Cosan technical analysis: after last week's plunge the stock rebounds 10%, closing right on its 7-session high and bouncing off its own 20-day moving average too. The fresh sell signal is only in its second week, but the confirmation week closes higher — a warning our model flags with an early-exit alert. Setup quality stays ordinary, and the quality band marks trading as not recommended.
