a column on conversions would fulfill one of your promises
I'll send in an answer today to the magazine. I don't think that this question is worded appropriately (LOL), but here goes.
-------------------------------------------
OK, I think Iâve explained this before, but it may have a while back. First off, the basics are pretty simple. If you buy stock, say at $53, and sell $50 strike price calls, and buy $50 strike price puts, then you have a conversion. If the stock goes up or down $10 (or any major move), you will not make or lose any money. The price of the calls and puts together will work out to be around $3.00 ($50 strike price, plus the difference between $50 and $53). The call and put together are your âsyntheticâ short position, and the stock is your long position.
Be aware that this is not a totally ârisk freeâ position. There is a small chance that the stock will close right at the strike price of $50, which may cause a problem. Since you are short the calls, you have no control over the exercising of them, which would pull stock away from you, thus altering your overall position. And, since you donât know for sure if those calls are being exercised, you donât know whether you should exercise your puts. So theoretically you cold end up ânakedâ long or short the stock, which would cause market risk on the Monday after expiration day (3rd Friday of the expiration month).
The reason that some institutions and traders buy conversions is to either take a small mathematical edge from price disparities (pretty rare these days), or to have long stock in their portfolio that they can use to hit bids on downticks, resulting in profits when the stock goes down. If you have a conversion on, and you sell 1,000 shares at $53, and then buy it back at $51 (while keeping your calls and puts intact), you have made $2,000.
When I was on the trading floor, we loved doing the other side of this type of trade, the âreversalâ or âreverse conversionâ â because we enjoyed making money on the short stock sale portion of the equation. So conversions can be a âwin-winâ at times.
As always, be sure you understand options very well before getting involved.
All the best!
