For investors in IBM common stock (NYSE: IBM), can delayed deals close after July’s reported shortfall as a historically favorable period approaches?[1][4]

The October 24, 2026–February 14, 2027 window gained in all 15 selected midterm years, versus 85.0% across 2006–2025. How much confidence should that seasonal record inspire?[4]

July’s business backdrop

IBM’s July 22 release reported Q2 revenue of $17.2 billion versus $16.977 billion a year earlier. Its 2026 forecasts were 4%–5% constant-currency revenue growth and about $1 billion more free cash flow year over year.[2]

Krishna’s July 14 letter cited the strong z17 launch comparison, weaker Z and Transaction Processing, spending diverted toward scarce hardware before expected price increases, and cybersecurity distractions. IBM failed to adapt quickly; delayed large deals drove most of the shortfall. Red Hat and Distributed Infrastructure showed strength, with roughly $500 million of backlog in the latter. Management still described the broader z17 program as ahead of z16.[1]

Fifteen selected midterm windows

TradeWave’s seasonal record covers 15 selected midterm-election years from 1966 through 2022. The 15.96% median long result describes complete windows before costs, not an expected gain from today. This limited sample does not establish an election-driven effect.[4]

A gain could involve substantial losses

The yearly range chart covers the same seasonal period each year. October 24, 2018–February 14, 2019 illustrates why endings can mislead: a 9.92% gain accompanied a move 15.66% below the starting price. The highs and lows establish neither their order nor a peak-to-trough loss or future limit.[4]

What happened inside each seasonal window

IBM: 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. The dashed line marks TradeWave’s median full-window result of 15.96%. 15 selected midterm-election years (1966–2022)

Broader histories temper confidence

Checking across all years tests how much the selected history matters: median results were 9.96% for 2016–2025 versus 7.71% for 2006–2025. The longer view is less compelling. Each comparison reuses selected midterm observations; the shorter sample also sits entirely within the longer, limiting independent confirmation.[4]

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.

What to inspect before October 24

October 24 is the next calendar checkpoint; October 5 observations cannot establish entry conditions. Compare this window’s histories and ranges in TradeWave. Below, the same 15 selected years supply an average seasonal path over the next 60 weekdays, October 6–December 28, 2026, separate from the full window. Recorded prices end October 5. The rescaled overlay illustrates historical shape, not a forecast or price target.[4]

Price history and the seasonal outlook

IBM recorded prices and TradeWave seasonal illustration. Blue shows recorded prices through 2026-10-05. The amber line overlays a section of TradeWave's seasonal trend, scaled to the last recorded price, using 15 selected midterm-election years (1966–2022). Its displayed dates are 2026-10-06 to 2026-12-28; 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

15 selected midterm-election years (1966–2022). 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.
