John Griffin believes someone is artificially suppressing the price of S&P 500 contracts, then profiting when the VIX settlement price comes in much higher.
Does the VIX Need Fixing? Sure Looks That Way
Last week’s CBOE statement tried to calm fears over the April settlement. The essential message: The suspicious activity in S&P 500 options “is consistent with normal and legitimate trading behavior.” We agree with at least the first half of that sentiment, as this behavior is becoming alarmingly normal — though only at the CBOE’s specially designed monthly settlements, and not at other times.
