A lot of floor traders, especially the younger ones, love to write naked options. "The fools," they say, speaking of the options buyer, they just keep giving me their money, and I keep selling 'em options that end up expiring worthless." For 11 months of the year, they, can report a 90 percent success rate writing options, but in the last month, seemingly out of nowhere, the market moves 10 percent and they find themselves shelling out a lot more money than they had made, or even going completely broke.
Victor Sperandeo in Principles of Professional Speculation, 1994
