Why Diamonds (DIA) options typically have a 30 cent bid-ask spread?

Discussion in 'Options' started by crgarcia, Sep 27, 2007.

  1. Compared to 10 cents on SPY and 5 cents or less on QQQQ options?
     
  2. I have never understood this argument.. Why do people still trade the diamonds over the dow emini?? Lower commission, higher margins, better spreads.. etc, etc, etc.
     
  3. I'm sorry, I don't understand your response - what does it have to do with OP's question? Which argument are you referring to?
     
  4. The average bid-ask is more like 20 cents, not 30 cents.

    I think it has something to do with the recent wild 100+ swings the DOW has been having, increasing volatility. When things settle down then the bid-ask will be less.
