Crash Protection For Tesla

Updated on

At the end of May, Elon Musk’s SpaceX sent two astronauts into space – the first manned launch from U.S. soil in nine years. Also at the end of May, Tesla (TSLA) made our list of top ten names. Since then, the stock’s up 256%.

Still Bullish On Tesla, But Others Have Issues

Our system is still bullish on Tesla. Our analysis of total returns and options market sentiment put Tesla in the top ten again on Wednesday. It was the only name from the May 28th top names cohort to appear in the November 25th cohort. Others, however, have suggested Tesla’s valuation may have gotten ahead of itself.

Rajesh Sawhney noted that Tesla’s market cap is greater than that of Mercedes (DDAIF), Subaru, Ford (F), Fiat (FCAU), BMW (BMWYY), Nissan (NSANY), Mazda (MZDAF), Hyundai (HYMLF), and Aston Martin (AMGDF) combined.

Bloomberg’s Joe Wiesenthal noted that Elon Musk is now richer than Bill Gates.

Wiesenthal also suggested that Tesla’s spike was a bubble driven by desperate speculators.

Even if you’re bullish on Tesla It’s Worth Hedging Here

Even if you’re bullish on Tesla, it might make sense to hedge here, in the event the stock corrects in the near term (as it did earlier this year). Here’s one way to do that.

I tried hedging 100 shares of Tesla against a greater-than-20% decline over the next several months two ways: ones with optimal puts (uncapped upside) and once with an optimal collar (capped upside).

Uncapped Upside – Unavailable

On Wednesday, if you scanned for an optimal put to hedge Tesla against a >20% drop over the next 6 months, you would have gotten this error message.

What “net cost exceeds threshold” means is that the cost of hedging against a >20% decline was more than 20% of your position value. So, by buying that hedge, you would have incurred more than the loss you were looking to prevent.

Capped Upside, Negative Cost

If you were willing to cap your possible upside in Tesla at 38% over the next six months, this was the optimal collar to protect against a >20% decline over the same time frame.

Here the net cost was negative, meaning you would have collected a net credit of $425, or 0.74% of position value, when opening this hedge, assuming, conservatively, that you bought the puts and sold the calls at the worst ends of their respective spreads. That worked out to an annualized cost as a percentage of position value of -1.32%.

When Tesla Pulls Back

If Tesla pulls back within the next few months, you’ll be able to buy-to-close the call leg on the collar above for a lot less than you got for selling it, and you’ll be able to sell the puts for a lot more. If you’re still bullish on Tesla then, you sell those appreciated puts to buy more shares.
