  • How Last Month's Hedge Helped Cushion The Blow For Tesla Longs 0 comments

    Five-Star Protection For Tesla Longs

    Last month, after a video surfaced of a Tesla (NASDAQ:TSLA) Model S sedan that had burst into flames, I posted a hedge for Tesla longs concerned about adding downside protection ("Five-Star Safety For Tesla Longs"). In this post, I'll recap that hedge and show how it reacted to Tesla's post-earnings dive on Wednesday, November 6th.

    The October 2nd TSLA Hedge

    This was the optimal collar*, as of October 2nd's close, that was designed to limit an investor's losses to 20% over the next several months, for an investor willing to cap his upside at 20% over the same time frame:

    As you can see at the bottom of the screen capture above, the net cost of that optimal collar was negative, meaning the investor would have gotten paid $50 to hedge.

    How That Hedge Has Reacted To TSLA's Drop

    Here is an updated quote on the put leg as of Wednesday's close:

    And here is an updated quote on the call leg:

    How That Hedge Protected Against Wednesday's Drop

    TSLA closed at $180.95 on Wednesday, October 2nd. A shareholder who owned 200 shares of it and opened the collar above on October 2nd had $36,190 in TSLA shares plus an outlay of -$50 on the hedge, so $36,140 taking into account the hedge.

    TSLA closed at $151.16, on Wednesday, November 6th, down 16.5% from its price on October 2nd. The investor's shares were worth $30,232 as of Wednesday's close, his put options were worth $3,890, and if he wanted to close out the short call leg of his collar, it would cost him $840. So: ($30,232 + $3,890) - $840 = $33,282. $33,282 represents an 8% drop from $36,190.

    More Protection Than Promised

    So, although TSLA had dropped by 16.5% at the time of the calculations above, and the investor's hedge was designed to limit him to a loss of no more than 20%, he was actually down only 8% on his combined hedge + underlying position by this point.

    Options Give You Options

    Being hedged gives an investor breathing room to decide what his best course of action is. A TSLA long hedged with this collar could exit his position with an 8% loss now, he could wait to see what happens, or if he remains bullish on TSLA, he could buy-to-close the call leg of this collar, to eliminate his upside cap. If he's even more bullish, he could sell his appreciated puts, and use those proceeds to buy more TSLA. He has those options because he's hedged.

    *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. Portfolio Armor's algorithm to scan for optimal collars was developed in conjunction with a post-doctoral fellow in the financial engineering department at Princeton University. The screen captures above come from the Portfolio Armor iOS app.
