Everywhere.....these are the basic criteria but subject to many other factors......
By the standards established by the options exchanges, options can only be listed on securities meeting all the following criteria at the time of listing:
•The underlying equity must be listed on the NYSE, AMEX, any national stock exchange or Nasdaq National Market.
•The closing stock price must have a minimum price of $3.00 per share for a majority of the trading days during at least five trading days.
•There must be at least seven million publicly-held shares outstanding excluding shares held by directors or holders of 10% or more of the underlying equity shares. (e.g. the public "float" must be seven million or more.)
•There must be at least 2,000 shareholders.
Generally, there would be a minimum of five days from the IPO date before options could be listed on any stock, but this criteria alone would not guarantee listing.
