Innovator Growth-100 Power Buffer ETF - December (NDEC)

The Innovator Growth-100 Power Buffer ETF (NDEC) is an exchange-traded fund that gives you exposure to the largest growth companies in the United States — the NASDAQ-100 — while mathematically limiting how much you can lose in a bad year. It does this using options, which are bets on future stock prices. The result is a fund that trades off unlimited upside for real, measurable protection on the downside.

How the buffer works

When you buy NDEC, you are actually buying into a one-year contract. On the contract’s anniversary (December, for this specific fund), Innovator resets everything and creates a new contract. Here is what happens inside that year.

If the NASDAQ-100 stays flat or goes up, you benefit. Your fund moves in line with those 100 stocks. But Innovator has capped your gain — you will not capture every dollar of upside. That is the trade-off: you give up some of the gain in exchange for protection.

If the NASDAQ-100 falls, the buffer kicks in. The first 15% of losses are entirely absorbed by the fund’s options strategy. So if the index drops 10%, you lose nothing. If it drops 20%, you only lose 5% (because the 15% buffer shields you). That is real money saved in a bad year.

But there is a limit. Once losses exceed 15%, you start to lose. If the NASDAQ-100 falls 30%, you will lose 15%. The protection ends; you are exposed like any other investor.

Why companies use this strategy

This structure appeals to people who believe growth stocks are the right bet for the long term, but who lose sleep over the volatility. A tech crash in 2022 scared many investors. Some moved away from growth entirely. Others just wanted a way to own growth without the full downside risk.

NDEC says: stay invested, but sleep better. You will not beat the market in good years. In bad years, you will outperform. Whether that trade is worth it depends on your temperament.

The reset and the one-year term

The “December” in NDEC’s name matters. Every December 31, the fund’s protection contract ends and a new one begins. Innovator sets new cap levels based on where interest rates and volatility stand. If volatility is high, the cap (the limit on how much you can gain) might be lower, because it costs more to buy the protective options. If volatility is low, the cap might be higher.

This annual structure creates something other ETFs do not: a known end date. You own this ETF for a specific one-year period. At the end, you face a choice: hold through to the new contract, sell, or move to a different buffer fund (Innovator offers multiple versions with different reset months and different buffer percentages).

The annual reset is also a moment of price adjustment. The old contract’s final value is what you get if you sell that day. The new contract opens at a fresh price. If the old year was good for the market, you might decide to take your gains and leave. If it was bad, the buffer kept you from the worst.

How the options work (briefly)

Innovator does not just decide the buffer and cap arbitrarily. They are funded by buying and selling options. To protect you against the first 15% of losses, they buy protective puts (the right to sell the index at a certain price). To pay for those puts without the cost running wild, they sell call options (giving someone else the right to buy the index at a higher price). The balance of these options creates the buffer and the cap.

You do not need to understand options to own NDEC. But it is worth knowing that your protection is backed by real financial instruments in the market, not just a promise. If the market moves more sharply than anyone expected, the options may not perform exactly as Innovator projected — but that is rare.

Who should own it, and who should not

NDEC suits an investor who has a moderate time horizon (three to five years or more), believes in growth stocks, and wants to reduce the emotional pain of big drawdowns. It does not suit someone trying to beat the market or someone who thinks volatility is an opportunity to buy more. It also does not suit someone with a long enough horizon and strong enough stomach to ride out volatility raw — they would be better off in a plain index fund and save the expense ratio.

To research this fund properly, read Innovator’s fact sheet and prospectus. They explain the cap levels for each annual period, which is critical — a capped return means you need higher-than-normal gains just to match a normal growth fund’s return. Ask whether the cost of that protection has justified itself over several cycles, or whether you would have been better off unhedged.
