VIX histórico de movimento esperado Cboe Volatility Index
A cada dia útil, após o fechamento, registramos o que o mercado de opções estava precificando — por expiração, antes de o resultado ser conhecido. Quando uma expiração passa, o resultado é registrado ao lado da estimativa original. As estimativas nunca são revisadas após o fato.
