QQQ Pulled In $1.66 Billion. The Same Index Trades Under a Cheaper Ticker.

Investors put $1.66 billion into the Invesco QQQ Trust (NASDAQ:QQQ) in an ETF flow count dated October 14, 2026. No other fund on the list took in more. That money bought the Nasdaq-100. So did the $380.7 million that went into the Invesco NASDAQ 100 ETF (NASDAQ:QQQM). Both funds come from Invesco and track the same index, but QQQ has the higher fee. That gap comes out of holders’ balances every year.

Identical Exposure at Two Different Prices

Both funds track the Nasdaq-100 Index, which holds the 100 largest non-financial companies on the Nasdaq. As of June 30, 2026, QQQ’s largest positions were NVIDIA (NASDAQ:NVDA | NVDA Price Prediction) at about 7.6% of net assets and Apple (NASDAQ:AAPL) at about 6.7%. QQQM follows the same index rules, so it holds the same companies at the same weights. In practice, the two portfolios overlap completely.

From October 7 through October 15, QQQ moved -4.48% and QQQM moved -4.47%. The flows had the same shape, too. Each fund’s inflow was 0.30% of its assets. QQQ manages $503.49 billion and QQQM manages $111.96 billion. A buyer choosing between them picks the same stocks either way. The only real choice is the price.

How a Tiny Fee Gap Grows Over Decades

The expense ratio is the annual fee, shown as a share of assets. The fund takes it out of its assets a little each day. The charge shows up only as a slightly smaller balance. The gap between QQQ and QQQM is small on paper. Two forces make it bigger over a long holding period.

First, the fee grows with your balance. QQQ’s share price rose 517.89% over the past ten years. As a Nasdaq-100 holding grows, the same percentage gap costs more dollars each year. Second, money paid in fees stops compounding. A dollar lost in year one is a dollar that sits out every rally that follows.

In December 2025, QQQ shareholders approved converting the fund from a unit investment trust to an open-end ETF, and Invesco cut QQQ’s fee as part of that change. The cut narrowed the gap, but QQQM still charges less. Before you put a dollar figure on it, take the net expense ratio from each fund’s current prospectus, subtract one from the other, and multiply by your balance. Then multiply by the years you plan to hold. Lost compounding pushes the true cost above that simple product.

Why QQQ Still Pulls in the Big Money

Invesco places QQQ among the most-traded ETFs in the U.S. by average daily volume. All that trading keeps the bid-ask spread tight (the spread is the gap between buy and sell quotes). On a large order, a tighter spread can lower trading costs.

The options market matters even more. Institutions use QQQ options to hedge, income funds write covered calls on it, and traders lean on it to manage risk. For a desk that holds QQQ for hours or days, the expense ratio barely matters because the fee accrues daily. Over a short holding period, it amounts to a rounding error.

Share price is a smaller factor. QQQ trades near $723.80, while QQQM trades near $297.99. Investors who buy whole shares can deploy small sums more exactly with the lower-priced fund.

Same Index, Two Different Answers

A trader and a long-term holder can look at the same two tickers and reasonably choose differently. If you trade often, write options, or hedge in size, QQQ’s liquidity may be worth its fee. If you plan to hold a Nasdaq-100 position untouched for decades, the fee gap is close to the only thing that separates the two funds. Switching has a cost of its own: selling QQQ in a taxable account could set off capital gains tax. Before you add new money, ask yourself one question: How long will I hold this, and will I ever use its options market? Your answer tells you whether the extra fee buys anything you will actually use.
