Same Thursday, Very Different Stories: Reading Implied Moves for Western Digital, Nokia and Spotify

Four companies report earnings on Thursday, Oct. 22, 2026, and the options market is pricing a move of roughly 9% to 12% for them. The numbers are in the same range, but the stories are very different. That makes Thursday a handy classroom for one of the most misunderstood ideas in options: what an implied move does and does not tell you.

Quick refresher: what is an implied move?

An implied move is the market's rough price for earnings uncertainty. Traders typically estimate it from the at-the-money straddle: a call and a put at the same strike, expiring just after the report. Add the two option prices, then divide by the stock price. A $100 stock with a $10 straddle implies a move of about 10% in either direction.

It is a price, not a prediction. It says nothing about direction, and it is not a cap on how far a stock can move.

The lineup (figures as of Oct. 19, single source)

These figures come from one data site, Earnings-Watcher, and change through the week. They compare each implied move with that site's historical average, which it measures using the largest move reached on the reaction day, not the closing move.

• Western Digital (WDC): reports after Thursday's close. Implied about 10.3%; 10-year average about 9.4%; two-year average about 11.8%.
• Nokia (NOK): reports in Europe Thursday morning, before the U.S. open. Implied about 10.5%; 10-year average about 3.3%; two-year average about 5.1%.
• Spotify (SPOT): reports before the U.S. open. Implied about 9.4%; 10-year average about 11.7%.
• Bloom Energy (BE): reports after the close. Implied about 12.4%; 10-year average about 16.5%.

What the gaps might mean

When an implied move sits above history, as with Nokia, it can reflect:

• genuine uncertainty,
• a recent change in how the stock behaves (Nokia's two-year average is higher than its 10-year one), or
• simply strong demand for options.

When it sits below history, as with Spotify, the market may be pricing in less movement than the stock has shown in the past. Or past behavior may not be a good guide to this report. None of these readings is a signal on its own.

Three lessons the data teaches

1. How a "move" is measured changes the story. After Western Digital's August report, the data site recorded a close-to-close move of about -13.0% but a peak intraday move of about -21.5%. Quoting the bigger number alone would overstate what a holder at the close experienced. Always ask whether a figure is close-to-close or intraday.

2. The expiration you choose changes the number. For Bloom Energy, the 12.4% figure from one source compares with about 10.95% for a weekly option and about 19.8% for a monthly option on a second site, OptionSlam. Different expirations include different amounts of extra time. Two sources can both be "right" and still differ.

3. IV crush is the quiet cost. Option prices usually fall after the report as uncertainty clears. This drop is called IV crush. A buyer of a straddle generally needs a move larger than the implied move to come out ahead, and even a big move may not be enough if volatility collapses.

Risk, plainly

Buying options can mean losing the full premium. Selling them is riskier: selling a straddle or naked options can expose a trader to very large and, for naked calls, theoretically unlimited losses if a stock gaps. Defined-risk spreads, such as vertical spreads or iron condors, cap the maximum loss, but they cap gains too, and a gap beyond the short strike can still produce the maximum loss. Western Digital's August intraday swing shows how tails can exceed an options-implied range, and past moves do not predict future ones.

The bottom line

Thursday's four reports are a reminder that an implied move is a price with context attached. Its history, its measurement method and its expiration all matter. The point of reading these numbers is to understand what the market is charging for uncertainty, not to guess which way a stock will go.

Earnings-Watcher figures are as of Oct. 19, OptionSlam figures were checked around Oct. 20, and both can change before the reports. This article is educational commentary on public market events, not personalized investment, trading, or tax advice.
