  • Follow-Up: How Those Apple Hedges Performed After The Company's Earnings Miss 0 comments
    Jan 24, 2013 10:00 PM | about stocks: AAPL

    In a recent post ("Two Ways of Hedging Apple and Research In Motion"), we mentioned that Tim Knight's bearish November post about Apple ("How Apple Became Japan") looked prescient. It looks even more prescient now after Apple's post-earnings tumble. In our post, we mentioned a few different hedges on Apple. Below is a quick update of how those hedges reacted as Apple dropped more than 12% on Thursday.

    February Expiration Optimal Put

    This was the optimal put* we first mentioned in an August 17th tweet. This was the optimal put to hedge against a greater-than-20% drop from Apple's share price at the time (about $648).

    Feb AAPL Optimal Put Update

    July Expiration Optimal Put

    This was the optimal put we mentioned in our previous post on hedging AAPL, to hedge against a drop of greater-than-20% from Apple's price at the end of last week (about $500 per share).

    July Expiration Optimal Collar Update

    And, finally, this is an update on the optimal collar** we mentioned in that previous post. This one was designed to protect against a greater-than-20% drop from its then-current market price of about $500, while capping an investor's upside at 15% over $500 per share. That was a negative-cost collar, because the income from selling the calls more than offset the cost of buying the puts, so an investor opening that collar was effectively getting paid to hedge. Note that the call leg here has dropped in price, as expected. If our hypothetical investor turned bullish on Apple today, for some reason, he could buy back that call leg here for less than he sold it for, removing his upside cap.

    July AAPL Collar Update

    *Optimal puts are the ones that will give you the level of protection you want at the lowest possible cost. Portfolio Armor (available on the web and as an Apple iOS app), uses an algorithm developed by a finance Ph.D to sort through and analyze all of the available puts for your stocks and ETFs, scanning for the optimal ones.

    **Optimal collars are the ones that will give you the level of protection you want at the lowest net cost, while not limiting your potential upside by more than you specify. The extension to the Portfolio Armor algorithm to find optimal collars was developed by a post-doctoral fellow in the financial engineering department at Princeton University.
