Altus research
Five studies of the option surfaces beneath the US large-cap index, in reading order: the two readings, then recoveries beneath the index, then what a fall does to protection, at the surface, at the held strike and at the bid, then correlation on falls. Start with the readings; the audience filter leaves each desk its own.
Every item states its date and, where readings appear, the data they come from. Nothing here is a performance report or a recommendation.
