Research Affiliates Deletions ETF (NIXT)

NIXT buys stocks that just got deleted from the S&P 500 and other major indices. The idea is that when a stock gets kicked out, index funds sell it, the stock falls, and the market forgets about it. NIXT bets that investors are overreacting and the stock will bounce back. It is a contrarian play on index-driven forced selling.

What happens when a stock gets deleted

A stock gets kicked out of the S&P 500 for specific reasons. Maybe it fell below the market-cap threshold. Maybe it moved its headquarters. Maybe it went bankrupt or ran into serious problems. The deletion is a public signal: this company no longer qualifies.

When that happens, two things occur in quick succession. First, every index fund that owns the stock has to sell it. They have no choice. The rules say the stock is no longer in the index, so the index fund has to drop it. That selling pressure pushes the price down. Second, the stock loses the halo of being in the S&P 500. It becomes invisible. Fewer analysts cover it. Fewer news stories mention it. It falls out of the conversation.

That is when NIXT shows up.

The contrarian bet

Research Affiliates, the firm that sponsors NIXT, thinks the market overreacts. When a stock gets deleted, sure, something is wrong. But investors panic-sell too hard. The stock becomes dirt cheap. That is a chance to buy.

NIXT follows a rule-based system. It looks at stocks deleted from major indices. It buys them. It holds them for a set period—typically several months or a year. Then it removes them from the portfolio by rule and moves on to the next batch of deletions.

There is no stock-picking. No judgment call about which deleted stock is a true gem and which is genuinely broken. The fund just buys the basket of the recently rejected and waits.

Why this works sometimes and fails sometimes

The logic is appealing. Forced selling by index funds does push prices lower, even for decent companies. Reduced attention does create opportunities. A retailer that missed a quarter and got deleted might recover. A manufacturer hit by a temporary supply crunch might fix it.

But deletions also signal real trouble. A company might be deleted because it is actually failing. It might face fraud investigations. It might be headed to bankruptcy. Buying the basket means you get a mix: some turnaround stories and some genuinely broken businesses. Your average return depends on whether the winners outnumber the losers badly enough to make money.

The portfolio makeup

NIXT’s holdings tilt toward small and mid-cap companies. Big companies rarely get deleted—they have to really fall apart to drop out of the S&P 500. Small companies get deleted more often and for simpler reasons: they grew too large and got deleted because they crossed a threshold, or they shrank and fell below the minimum. Smaller companies are also harder for investors to track and easier to misprice.

Because of this size bias, NIXT swings more than the overall stock market. You are getting exposure to smaller, less-covered companies. That means higher volatility.

The fund also trades its holdings frequently as new deletions come in and old positions age out of the strategy. This turnover costs money. Every time the fund buys and sells, there are fees and spreads. Your expense ratio covers these costs, so you pay for the turnover whether the strategy makes money or not.

Costs and trading the fund

The expense ratio is higher than a plain index fund but reasonable for a specialized strategy. NIXT trades on major exchanges. The trading volume is modest compared to mega-cap ETFs, so bid-ask spreads are wider. You will pay more to buy or sell than you would in a mega-cap fund.

Who should own NIXT

Own it if you believe index-driven selling creates real mispricings. Own it if you are willing to hold smaller, less-covered stocks and accept higher volatility. Own it if you think the market’s reaction to index deletions is irrational and that a systematic approach to buying the rejected will work over time.

Do not own it if you want broad diversification or if you need your portfolio to be stable. Do not own it if you are uncomfortable with the idea that you will sometimes buy genuinely troubled companies that do not recover. Do not own it as a core holding; it works best as a small, tactical satellite position.

How to think about it

Read the fund’s prospectus and Research Affiliates’ explanation of the strategy. Look at the holdings. Ask yourself: are these companies that temporarily fell out of favor, or are they companies with real problems? Check the recent history of index deletions. Were they mostly bargains that recovered, or were they mostly troubled companies that stayed troubled?

If the contrarian bet makes sense to you and you accept the risks, NIXT offers a systematic way to execute it. If not, it is a specialized tool that is not for you.
