Reinvesting a put hedge payout after a crash: the arithmetic


A hedge payout provides money; the decision to keep or reinvest it determines the next exposure. Reinvestment benefits from a subsequent rebound and loses more if the market keeps falling. The payout alone cannot establish which path will follow.

The comparison concerns total wealth after the stated costs. A lower loss in one scenario does not establish higher expected geometric growth; that requires probabilities and the complete investment path. No trade or allocation is proposed.

The parent put-option study explains why whole-portfolio compounding includes what happens after a hedge pays. This worked example isolates that mechanism with invented inputs, without trying to infer a crash date or a market bottom.

Key takeaways

  • Reinvesting a hedge payout increases exposure to the market’s next move.
  • That helps in the modelled rebound and hurts in a further decline.
  • The scenarios omit earlier hedge premiums and assign no probabilities, so they cannot identify a growth-optimal rule.

Specify the payout rather than inventing an option backtest

Start with a hypothetical $100,000 portfolio. It buys 980 equity units at $100, using $98,000, and spends the remaining $2,000 on a hedge. The equity price subsequently falls to $60, a 40% decline. At that moment the hedge is sold for $20,000.

The $20,000 is an assumed gross sale value, including recovery of the $2,000 premium. It is ten times the premium, equivalent to an $18,000 gain on that sleeve. It is not a quoted option price, observed return or claim that such cover was available at the stated cost.

The equity is now worth $58,800. Together with the sale proceeds, total wealth is $78,800, down 21.2% from the original $100,000. A separate $100,000 all-equity comparator would be worth $60,000. Its initial equity exposure differs, so attributing the entire $18,800 wealth difference to option profit would be incorrect: $800 comes from having started with $2,000 less equity during the decline.

All values are nominal US dollars. There are no dividends, interest, fees or further premiums. The hedge is gone after sale; no continuing protection is assumed.

Three choices from the same $78,800

Keeping the whole payout as cash leaves 980 equity units and $20,000 cash. Reinvesting half buys $10,000 ÷ $60 = 166.67 additional units, leaving 1,146.67 units and $10,000 cash. Reinvesting all buys 333.33 units, leaving 1,313.33 units and no cash.

Each version has exactly $78,800 immediately after this decision. The arithmetic creates no wealth at execution; it changes sensitivity to the next equity move.

Subsequent equity priceKeep payout as cashReinvest halfReinvest all
$40$59,200$55,867$52,533
$60$78,800$78,800$78,800
$80$98,400$101,733$105,067
$100$118,000$124,667$131,333

These are conditional hypothetical outcomes, rounded to whole dollars. The payout and reinvestment CSV contains precise quantities, tax assumptions and portfolio returns.

A return from $60 to $100 is a 66.67% equity gain, not 40%. With all proceeds reinvested, the extra 333.33 units grow from $20,000 to $33,333. That explains the $13,333 advantage over retaining cash in that rebound scenario.

If the price instead falls to $40, those units are worth only $13,333. The same decision then leaves $6,667 less than keeping cash. Neither calculation assumes the initial sale happened at the bottom.

A tax bill changes the capital available

For a separate illustration, assume an immediate 25% tax on the $18,000 hedge gain, with no offsets. The $4,500 payment leaves $15,500 for reinvestment at $60. Combined equity ownership becomes 1,238.33 units.

At a subsequent $100 price, that version ends at $123,833, compared with $131,333 in the before-tax full-reinvestment case. The $7,500 terminal difference includes the $4,500 tax and the rebound forgone on that money. This is a tax sensitivity, not an after-tax comparison with an unhedged investor, whose own tax position is unspecified.

What this example can and cannot show

It makes the cash-flow decision reviewable. It does not establish a positive expected return, an appropriate allocation, or a rule for recognising a crisis. The preceding years of hedge premiums are omitted; including them could materially change the full strategy's compound return. See recurring hedge-budget drag.

Methodology and sources

The payoff definitions follow the Options Industry Council, but every price, payout and reinvestment fraction here is our hypothetical assumption. Universa's reported sleeve returns use another denominator; the Spitznagel case study explains that distinction without treating them as inputs to this model.

FAQ

Does reinvesting a hedge payout always improve the result?

No. In our hypothetical example, putting a $20,000 payout into equities at $60 produces $131,333 if the price later reaches $100, but only $52,533 if it instead falls to $40. Retaining the payout as cash produces $118,000 and $59,200 respectively.

Is the payout assumed in this article an observed option return?

No. A $2,000 premium and a $20,000 realised hedge sale are specified hypothetical inputs. The article does not price an option, establish that such a payout was available, or claim that it reproduces a real investment strategy.

How can tax affect hedge reinvestment?

In the explicitly hypothetical 25% tax example, a $20,000 sale against a $2,000 premium creates an $18,000 taxable gain and a $4,500 tax payment. Only $15,500 remains for reinvestment. Actual tax treatment, timing and loss offsets depend on the investor's circumstances.
