Let me say first things first......The brokers love collars because they make TWO commissions instead of one commission. Depending which broker you are using, options pricing look something like the following....$40 for the first contract, then $1.40 for each additional contract. In a collar, on 100 hundred shares, you'd be selling one contract of covered calls and buying one contract of puts. This would equal $80 in commissions, which now boost's the cost of the stock to $36.80 (35.70+$0.80 commission per share). That's an exspensive $34 stock!
The main key here (other than making your broker rich) is do you want to sell the stock in six months, or is this a long term by and hold. If it's a long term by and hold and you have done your homework, then the put is a needless expense.
Lets take UPS. I know I'm in it for the long term and my homework indicates that it's an extremely strong stock. Despite this, I also know that the share price will vary up and down based on market conditions and the business climate.
Using the example in your post, here's what you can do using covered calls only:
Buy 100 Shares XYZ @ ($34 per share)= +34
Sell 1 Six Month 40 Call = -2
Net debit=$32
Now, the net cost of your stock is $32, or you have just protected yourself down to $32 (a 6% decrease). You have also just put $200 into your pocket for the next six months, unless the stock rockets up to $40 or above (a 17.6% increase in 6 months) and is called. Then you have made an $8 profit ($6 on the stock and $2 on the covered call, or a 24% profit). If we let the options expire worthless, take the two dividends =$50 minus the one covered call option of $40 and you've made another $10.
Now.....6 months later, whatever the share value is, you sell another $2 covered call. Your original share cost drops to $30 per share and the above is repeated.
If your holding the stock as a long term investment and do the above, the $34 stock actually pays for itself in 8.5 years ($34/$4 per year). Again, this is without commissions and dividends.
Just another way of looking at it. Hope it helps..........
