Quote from OddTrader:
A problem is too many sellers and too little buyers would artificially lift many options prices to be higher than normally needed.
Higher options prices would discourage not only potential buyers for speculation but also buyers for hedging. Sellers competing each other would make the premium up to a higher and higher level.
The overall equity market would be forced lower because that is the only way to make money for the professionals.
Trading options can be done with very limited knowledge in options, cf Korean options market that would make prices of options very cheap to beneficial to all market players.
Basically I think the opposite is true on all pretty well all counts. Also overall market volitility, as well as supply and demand dictates the price of options and a bear move will tend to increase the cost of the options whilst a bull move will normally reduce the cost of the options, these are general comments.
