Quote from Don Bright:
Still a pretty simplistic strategy. Remember, when trading options, always check the conversion prices. Sell call, buy put, buy stock.. and then take the net, add to strike price, and you'll see that 99% of them are within 1% of fair value (based on either long or short interest rates, and time/dividends).
Credit spreads "blow up" about 5 in twenty times (just an estimate), and when they do, you're going to take a long time getting back anywhere near even...and the commish adds up.
Much akin to betting red or black....waiting for the zero or double zero to pop up to wipe you out.
And then, there is the slippage of not being able to get in and out like the floor traders can.
Good Luck!!
