S&P

The S&P 500 is the oldest, most studied index of stock market performance. Hedgematic uses an S&P ETF to capture stock market income and gains. Your brokerage account and any retirement accounts each may have S&P holdings.

Hedgematic tracks S&P holdings in “S&P units”. Each unit is valued at the current S&P average. Your ETF will be priced differently. When you are directed to buy or sell so many units, multiply by the current S&P and divide by the current ETF to get the number of ETF shares to transact.

On day 0, inflation adjusted values and actual dollars are the same. In the first year, as displayed here, you have deployed all Roth assets to S&P.

Following the initial purchase, you are not directed to make any additional purchases, with the exception of reinvested dividends. (there are also in-kind rollovers). In effect, your S&P assets are split into individual tranches, each targeted at a particular year and “held to maturity.”

Hedgematic specifies S&P unit withdrawals for each year. You could just uninstall the app and follow the plan, withdrawing your yearly sums. More likely, you will look to rebalance each year.

The dollar figures shown in future years are estimates denominated in today’s dollars, so you should not expect them to match your future sale proceeds. Your proceeds, if you do back out future inflation, may come out higher or lower than the today’s dollar figures shown, which are merely predictions.

There is a chance that these proceeds may not meet your specified after-inflation expenses. You indicated your tolerance for this outcome with the risk aversity you included when you created your profile. But there will be a payday every year. Barring catastrophe, you will not run out of money.

Above is an out-year display.

At the top of the screen, you see you are holding multiple lots of S&P. In this case, we are looking at a Roth account, so each lot may have included a mix of reinvested and rolled-in shares.

At the bottom of the illustrated screen, you are instructed to sell part of one lot of your holdings and the entirety of another.

Sale proceeds wind up in cash where they are drawn to support your year’s expenses.
