Most changes in the FTSE are small, but extreme outlier events occur far more often than a normal distribution would suggest.

Exhibit 2
Graphed above are the 5-day % changes observed in the FTSE since 1984. Anyone care to explain how they would have coped with some of those changes if they were short options ?
They say a picture paints a thousand words but what the above graphs cannot illustrate is the massive (and I mean MASSIVE) spike in IV as writers scramble to BTC short option positions and the fundies BTO as portfolio insurance. It is the massive IV spikes as much as the underlying fall that would blow all but the most conservative naked Put writers sky high.
