Whew... good questions... let me see if I can get all this in...
Keep in mind that only two kinds of cattle contracts are offered for trading - Live Cattle and Feeder Cattle - and each has it's own definitions, months, trading patterns, etc.
I would consider a cow/calf operation to be something of a hybrid between the LC and FC because of 1) the cow and calf age differential, and 2) the endless possibilities of what's done with each of them in the future. I don't know your numbers but would anticipate a combination of multiple LC and FC contracts proportionate to your poundage needing protection... not speculation.
In the above scenario, I'm talking only about protecting your 'growing' cattle investment against future declines in market price.
No, I'm not suggesting writing options against a futures contract - WRITING OPTIONS AGAINST A FUTURES CONTRACT IS NOT A 1:1 THING LIKE MOST PEOPLE THINK...THAT ONLY APPLIES IF YOU HOLD THE COMBINATION TO EXPIRATION! On the way there, you may well find your futures price changed, but the options didn't follow proportionately... this is what's know as the Implied Volatility differential.
I'm not sure what you mean by 'covered'... against his own cattle or a futures contract. Keep in mind that the right time to sell 'physically' may be a lot differenct than when to sell 'financially' when market prices are the best. If you really get knowlegable about futures and options, you can get yourself to the point where you'll be able to 'not buy' cattle at the wrong time of year just because they're cheap... they're cheap for a reason.
But if he hedged against his calves and it was time to sell from a 'physical' standpoint, he could do so and continue to hold the option to possibly take further advantage of the option... But now he's speculating rather than hedging because if he's wrong he can lose what he gained in the first place... so now he might want to consider either selling out of his position or selling (hedging) against it to mitigate his risk - managaging risk is what it's all about... not speculating.
Options are rarely exercised because it's more profitable to either sell or let them expire... and the Call holder would never exercise at a price below his strike price PLUS what he paid for the option... that's his real cost basis.
Hope this helps, Richard
