DeMark and McMillan have written that options may make good vehicles for day trading. But I look at the spreads and liquidity of even the actively traded contracts and I wonder if these guys are right. I mean day-trading usually entails taking fractions of a point. Since most options have delta's less than 1, wouldn't the transaction costs, spread + commissions, eat away too much at a one day move in option price (which in $ terms will be less than that of the stock)? I realize options offer leverage; when a $1.00 call rises to $1.50 that's a 50% move. But it's also only a $.50 move that will be significantly decreased once spread and commissions are lopped off. So, do any of you have opinions on whether or not options are suitable for day (or few day) trading and rules of thumb on which options would make the most sense to use? (I imagine near-terms with strikes close to ATM.) Thanks again. No more options questions for today.
