That's the problem with learning all about options before actually caring for the reason they exist: risk management. Options can be replicated with a portfolio, which usually requires a certain minimum size. Investors with a lesser budget would then buy the smaller units of "risk management".

In a way portfolio management through risk diversification isn't free lunch. For example if an investor has $1000 he can't realize a portfolio weight of 10% in a stock that is worth more than $100 per share.

Right now the market can bake those risks into the option prices.

Also, if there is demand for different margin requirements we'll add contracts with those requirements.

It will be pretty interesting to see what spread emerges between calls and puts in these circumstances.

Care to speculate? ;-)
