After QQQ's August gain, investors weighing an October entry face a practical question: how much confidence does its seasonal record deserve?[1][3]

The October 25, 2026–April 26, 2027 window is still ahead as of October 9. All six selected midterm precedents finished higher, while broader histories include losses. That makes this a timely period to examine, with the central question being whether favorable endings adequately describe the risk of holding QQQ through the window.[3]

August performance in context

Invesco QQQ tracks the Nasdaq-100 Index.[2]

Invesco's September 17, 2026 review reported August returns of 4.22% at net asset value for QQQ and 2.72% for the S&P 500 Index. Different technology holdings and a larger average technology allocation chiefly drove relative outperformance; a smaller energy allocation was the largest relative detractor.[1]

Six selected midterm windows

TradeWave's study of six selected midterm-election years from 2002–2022 produced a median full-window long result of 11.61%. That favorable seasonal record concerns complete October-to-April periods, not returns available from today's price. The bars let readers compare the individual finishes behind the summary. Six observations support examining this calendar window, but cannot establish that midterm elections caused the gains or that the next window will repeat them.[3]

What a winning finish can conceal

The yearly range chart shows each year's same seasonal period, not the whole calendar year. October 25, 2018–April 26, 2019 illustrates why the ending result alone is insufficient: a positive 11.97% finish coexisted with a move 15.89% below the starting price. An investor holding throughout that period would have experienced a substantial loss along the way despite the favorable ending. The chart's highs and lows measure moves from the starting price; they do not establish their order, a peak-to-trough loss or a limit on future losses.[3]

What happened inside each seasonal window

QQQ: yearly seasonal range. Each year shows the same seasonal period. Bars show the price change at its end. Thin lines show the highest and lowest changes from the starting price during that period. The lines do not tell us which move came first or measure a fall from a peak. They are not suggested stop-loss levels.

Two broader histories

Checking across all years tests how much the favorable reading depends on selected midterms: windows beginning in 2016–2025 and 2006–2025 were both 80.0% profitable, weakening the perfect-record impression. Six selected observations limit confidence. The shorter comparison reuses 2018 and 2022; the longer reuses every selected year except 2002 and contains the shorter history, so agreement is not independent confirmation.[3]

Some years appear in more than one group, so agreement is not an independent test. A requested lookback can extend beyond available history; the observed years are listed above. Election-cycle groups use matching phases, not consecutive years. Results follow the direction shown: a positive short result means prices fell. Small samples and different market periods make the comparison less conclusive.

Historical shape before October 25

Recorded prices end October 8, 2026. The following price chart superimposes TradeWave's normalized average seasonal path using this article's six selected midterm years, allowing comparison of historical shape with recorded prices. Its illustration covers the next 60 weekdays, October 9–December 31, 2026, a separate horizon from the full seasonal window. Those future dates belong only to the illustration, not recorded prices; the path is neither a prediction nor a price target. Before October 25, the next question is how the favorable finishes compare with the losses endured. Inspect this same window across histories and its yearly ranges in TradeWave.[3]

Price history and the seasonal outlook

QQQ recorded prices and TradeWave seasonal illustration. Blue shows recorded prices through 2026-10-08. The amber line overlays a section of TradeWave's seasonal trend, scaled to the last recorded price, using 6 selected midterm-election years (2002–2022). Its displayed dates are 2026-10-09 to 2026-12-31; covering the next 60 weekdays. That is a different horizon from the full seasonal window above. It illustrates the historical seasonal shape, not a price target or forecast.

About this seasonal analysis

6 selected midterm-election years (2002–2022). The selected dates, years, direction, returns and ranges come from TradeWave. When a window boundary is a weekend or market holiday, TradeWave uses the next available trading session. SMN displays the returned results without recalculating them. A year label identifies the start of the historical window; a window can end in the following calendar year.

Green and red bars show the underlying adjusted-price movement. The range endpoints measure changes from the entry price, not a peak-to-trough loss. Historical results are before trading costs and do not guarantee future performance.
