Michael, for purposes of going ahead with this discussion, let's both agree that we are both people of above average intelligence, and that each has a solid knowledge and experience in trading both equities and options. Also, that we both fully understand the 4 basic options Greeks: Delta, Gamma, Vega, and Theta. Beyond that there may or may not be differences. I have a full time job and therefore cannot, nor do I want, to ever trade options for a living. Finally, let's both agree that we are both strongly driven by the desire to make money trading and both have an equal aversion to loosing, but both understand the need to take and manage risk.
Having said all of that, let's first dispose of the commission/spread issue, which we can collectively call transactional costs. No doubt that this can mount up. Yes, the synthetics you are suggesting do involve fewer "legs" than what I am doing. However, I believe that this is offset by (1) fewer total transactions and (2) lower transactional costs because I am using equities to a larger extent than you are. If we cannot agree on t his point, let's just say it 's even and move on to the next part.
In this connection, most of what I have posted about relates to one stock, AAPL. This is difficult to communicate here on the ET Board where so many are so dedicated to synthetics, but when I do my AAPL trading, I don't look at it, nor do I measure my success or failure, on a trade by trade basis. Rather I look at it as a long term chess match between me on one side of the board and the Markets on the other side of the board. I try my very best to stay one or two steps ahead of the market. When I contemplate my future moves I think in terms of buying or selling either the options or the underlying, and what such moves would have on my adjusted net position. Fortunately, in this day and age, I have electronic tools at my disposal, but I won't go into any details on this now, because this posting is not a commercial.
So, bottom line is: If I carefully contemplate my future moves contingent on what the market first does, I don't think what I am describing lends itself to contemplating synthetic alternatives. I totally understand and respect that there are those who feel very strongly in favor of the use of synthetics. That's wonderful. But it doesn't mean that those of us who don't share those strong feelings are somehow inferior as options traders merely because we don't share their passion for those concepts. It also doesn't mean that, as some have accused me of, we totally disregard the synthetic equivalencies. It just means that we don't place the same emphasis nor do we devote the same amount of time to them.
In conclusion, I have no animosity toward those who disagree with me. But let's face it, you nice folks are not the ones on the other side of that hypothetical chess board from me. Hell, there's enough room in this options game for all of us to prosper if we both concentrate on hard work, self control, and patience.
