Just saw this thread for the first time.
Let me add this little-known fact: If you are long the wings and short the middle at a ratio that makes you premium neutral, then as IV rises you get longer and longer vega, and make money. As IV drops, you get shorter and shorter vega, and ALSO make money.
Don't believe me? Put it up on your simulator and you will see for yourself.
To the Riskdoctor - Hi Charlie! I traded in T-bond options with you from '84 to '87 (dmo was my badge). Loved your book - I can vouch for the accuracy of the anecdotes - you have quite an amazing memory to recall them in such detail!
That's very interesting. Is that single month or a calendar? Can you give an example please. Thanks.
For the fans of Charles' books - he was quite the amazing plunger in those days. When a broker had a thousand of something to buy or sell, Charles loved to be the guy who yelled "sold" - leaving everyone else in the pit with their mouths agape. At the time, 100 lots was more than most locals would take - even the ones working for institutions!
