Married Put Critics: Aren’t Long Calls Better & More Profitable?

Critics Question: On March 21st, Google was at $397. I bought 1000 of the JAN 2010 350 Calls for $73. Today it’s worth over $240,000…The same $73,000 would have bought me 200 shares of Google and the 420 strike put option was a ton of money. But today the put is worthless and would it not just take away alot of profits??

RadioActiveTrading Staff Answer: Although Married Puts and Long Calls seem to have the same risk/reward profile, Long Call positions can be over traded and take on too much risk. Yes, the GOOG position worked out, but we never know the future. Here is a different example of how the Married Put would have been a better trade compared to a Long Call position:

On Sept. 9th STEC was at $40.95 and had 2 alternative cases:

Buy FEB 2010 45 Calls @ $6.30.

OR

Buy a Married Put:

Buy to open STEC $40.95
Buy to open FEB 2010 45 PUT $10.50
Amount invested $50.95
Guaranteed exit price $45.00
At Risk Amount $5.95 or 11.7%

Today the STEC is about $12 (down 71%) and the call is worth ZERO for a 100% loss.

The married put is worth $45.00 with the same max. loss of 11.7%. However, we wrote calls and made several points over the last couple months, which limited our losses to under 10% with the stock down 71%. Yes, you may have been able to sell short calls against your Long Call to also reduce the risk for that trade, but if you sold calls below the $45 strike price, you would have had to put up more margin to cover the spread.

So…Today the call is worthless, but the married put has less than a 10% loss.

The Long Call investor went bankrupt with nothing left to invest, but the married put investors next investment was a married put in GOOG and did very well.

This example assumes that the Long Call investor would take their full trading capital, let’s say $10,000, and purchased 16 Long Calls (total investment of $10,080) and the Married Put Investor would have purchased 200 shares of stock and 2 put options (About $10,200).

Pundits and gurus keep saying:

Long Stock + Long Put = Long Call.

It isn’t so.

Actually: Long Stock + Long Put = Long Call + CASH.

The missing ingredient that makes those two positions equivalent… at “parity”… is cash on deposit in an interest bearing account. That’s the mathematical truth (check “Black-Scholes”). So there is no advantage to trading a call unless that call is only a small portion of your tradeable capital, and the rest is tied up in an interest bearing instrument. (in The Blueprint, we discuss how to use the proper position sizing in Long Call positions to have a true parity to the Married Put position.)

In fairness to your question, YES, if we knew that a stock was going to double over the next 90 days, would we put CALLs rather than trade a married put….uuhh…YES, of course we would!!

Problem is, you never “KNOW” that a stock will do that.

Does trading a married put limit some of the profits, compared to just buying long stock or buying long calls?…uuhh…YES, of course it does. You can’t get an insurance policy for free. Anytime you limit risk, then you are also limiting some of your reward.
