Subject: Re: Covered call?
john, you could also sell puts. The put premium will pay off your student loans (less than the calls, but still not bad). If brk goes up, you pocket the put premiums. If brk goes down, you can sell the stocks immediately when you are put the the stocks. Your lost will be the difference between $500 (assuming you sold atm options) and future brk price. But your lost can be used to offset your huge unrealized capital gains of brk.

Comparing to selling calls, you may end up selling your brk but also a pretty big capital gains tax bill
