Mountain (MNTN) plunged 39% in its first hourly earnings candle, yet continued falling another 27.34%, ultimately delivering a hypothetical 26.28% next-day EOD gain for short sellers against just 1.13% MAE. Similarly, MRNA and KOD produced massive initial hourly gains exceeding 56%, followed by additional favorable excursions of 64.42% and 80.20%, respectively.

Some of the largest trading opportunities I’ve recorded in my Post-Earnings Momentum (PEM) database have come from stocks that already made extraordinary moves during their first hourly earnings candle.

But there’s a catch.

Our historical data suggests that larger first-hour moves generally produce greater volatility, larger adverse excursions, and lower win rates. In other words, the same setups that offer enormous upside can also expose traders to substantial losses.

However, when those massive initial moves DO actually continue, the results can be extraordinary.

Mountain (NASDAQ: MNTN) provided a nearly textbook example on November 4, 2026. Following disappointing quarterly earnings and weak forward guidance, MNTN plunged 39.00% during its first hourly earnings candle. Yet the selling was far from finished.

From the close of that initial candle, MNTN subsequently produced another 27.34% maximum favorable excursion (MFE), experienced just 1.13% maximum adverse excursion (MAE), and finished the following trading session with a hypothetical 26.28% gain for short sellers.

And MNTN isn’t the only example.

We’ve also documented Moderna (MRNA) and Kodiak Sciences (KOD), which weren’t actually post-earnings moves, but still produced similarly explosive continuation moves following initial hourly gains exceeding 50%.

These three setups demonstrate an important lesson about momentum trading: just because a stock has already made a massive move doesn’t necessarily mean the opportunity is over.

Mountain (MNTN): Company Overview

Mountain (NASDAQ: MNTN) is an advertising technology company operating in the technology sector, specializing in Connected TV (CTV) advertising.

Its platform allows businesses to deliver performance-focused advertising campaigns across streaming television services, combining television advertising with digital marketing capabilities.

At the time of the November 2026 earnings setup, Mountain had an approximate market capitalization of $352 million, placing it firmly within the small-cap category.

The stock also had approximately 9.65% short float, indicating that a meaningful portion of its publicly available shares had been sold short.

We trade both market cap and short interest as two variables for our post-earnings momentum database, neither market capitalization nor short interest alone establishes whether a stock will continue in the direction of its initial earnings reaction.

For that, we need to examine the earnings catalyst and subsequent price action.

---

MNTN Earnings Results & Fundamentals

Mountain reported third-quarter 2026 financial results on November 4, 2026, after the market closed. Unfortunately, the results were considerably weaker than analysts had anticipated.

The company reported earnings of $0.10 per share, compared with consensus estimates of $0.25 per share. That’s a staggering –60.00% earnings miss.

Revenue also disappointed, coming in at $80.25 million against expectations of $87.52 million, representing an 8.30% revenue miss. Interestingly, revenue still increased approximately 14.61% year over year.

So, while Mountain continued generating annual revenue growth, its financial performance fell significantly short of Wall Street’s expectations.

And the forward guidance didn’t offer much reassurance.

From a fundamental perspective, the bearish price reaction was understandable. Mountain hadn’t simply missed quarterly expectations. It had also communicated a substantially weaker near-term revenue outlook.

For a relatively small technology company, such a significant reduction in expected future revenue can trigger an aggressive reassessment of its valuation.

And that’s precisely what happened. Within the first hour following the announcement, MNTN shares collapsed 39%.

However, as we’ll see, the initial earnings crash was only the beginning of the PEM setup.

MNTN Technical Analysis & PEM Outcome

The most interesting aspect of this setup wasn’t necessarily Mountain’s disappointing earnings report. It was what happened after the stock had already lost 39% of its value in a single hourly candle.

The chart below shows the 1-hour earnings candle breaking below its most recent hourly, 4-hour and daily support levels.

---

This gave the setup a breakout score of 3 out of 3 in my tracking framework.

The technical direction also agreed with the fundamentals, which basically means the earnings report was objectively bearish (EPS and revenue miss + weak guidance) AND the price action was bearish also (-39% in a single hourly).

The candle’s wick structure was also notable.

The candle’s had virtually no upper wick and the lower wick was only a -5.78% retracement from the candle’s momentum-end, indicating some short covering and buying had occurred, but no where near enough to overwhelm sell orders flooding onto MNTN’s the tape.

---

From the close of the initial -39% earnings candle, MNTN moved a stunning +26.29% in the same direction with no more than a -1.13% adverse reaction.

Mountain had missed earnings estimates, missed revenue expectations, and issued revenue guidance substantially below consensus. The stock then sold off by about -39% in a single hour.

Based on my research, that produced a clean fundamental and technical catalyst with enough conviction to trade MNTN short and hold until the end of the next day’s trading session.

Here’s a look at both the PEM setup and the trade’s hypothetical outcome:

Arguably, the most important takeaway from the entire case study is that you didn’t need to rush in and sell during the first-hour earnings reaction or even right after that candle closed.

A patient trade could have waited for a retracement closer to the stock’s recent 6-9-12 EMA cloud or for some other form of confirmation, and still taken advantage of plenty of downside price action.

Either way, in Mountain’s case, from the close of hourly earnings candle, the stock fell another 27% during the next trading session. And that’s precisely why I study these setups.

Other Massive First-Hour Movers: MRNA & KOD

Mountain issn’t the only stock in my research to produce an extraordinary continuation after an already massive initial move. We actually have two other particularly interesting examples in our case study library, which came from biotechnology stocks Moderna (MRNA) and Kodiak Sciences (KOD).

Unlike MNTN, which was a bearish post-earnings momentum trade, both MRNA and KOD were bullish setups driven by positive clinical trial developments.

Let’s take a quick look at both momentum setups!

---

MRNA Case Study: A +56.9% First-Hour Move Leads to +64.42% MFE

On August 19, 2026, Moderna (NASDAQ: MRNA) made an explosive intraday move of more than +120%. Although this wasn’t a traditional post-earnings momentum setup, it was still one of the most explosive momentum moves I’ve recorded.

---

Moderna and Merck announced positive Phase 3 clinical trial results involving an individualized mRNA-based cancer therapy combined with Keytruda.

The news triggered an extraordinary reassessment of Moderna’s potential future value. And during its first hourly catalyst candle, MRNA surged a whopping 56.9%.

---

That’s an enormous move for a single hour. But just like MNTN, the initial reaction wasn’t the end of the opportunity.

Instead of toppping out, Moderna subsequently produced and +64.42% MFE and an EOD gain of +76% from the close of the hourly candle catalyst candle. The most stunning part is that the stock only move -6.45% against an entry at the hourly candle close.

Consider for just a second what that means…

A stock that had already gained nearly 57% during its initial hourly candle still managed to deliver another 64.42% favorable excursion from that candle’s closing price.

The example illustrates how a major catalyst can generate sustained directional pressure even after the initial price adjustment appears excessive.

---

KOD Case Study: +56% First-Hour Momentum Followed by +80.2% MFE

Kodiak Sciences (NASDAQ: KOD) provided an even more dramatic example on September 28, 2026. The biotechnology company announced positive Phase 3 DAYBREAK clinical trial results for two experimental treatments targeting retinal diseases.

During its initial 6 a.m. catalyst candle, KOD surged approximately 56% from its opening price.

---

By the time that candle closed, shares had already experienced an extraordinary repricing. But just like we’ve demonstrated with MNTN and MRNA, the rally still continued throughout the next trading session.

From the close of the initial catalyst candle, KOD produced an MFE of +80.20%, an adverse reaction of only -6.95% MAE, and approximately +69% in hypothetical EOD gains from a single intraday momentum trade.

The stock ultimately finished the session up 177.96% from its previous regular-session close.

And again, the most interesting aspect wasn’t simply the size of the initial move. It was the magnitude of additional trading opportunity available after that initial price reaction.

This example reinforces the idea that powerful fundamental catalysts can sustain extraordinary price movements well beyond the first reaction.

---

Comparing Three Extraordinary Momentum Setups

Putting all three of these setups side by side illustrates just how much favorable price movement can occur after an already enormous first-hour reaction.

Let’s take a look at MNTN, MRNA and KOD side-by-side:

Together, these three examples demonstrate the potential magnitude of successful continuations, which is NOT necessarily the same as the probability of achieving these results.

There’s also an important distinction between the catalysts.

MNTN was a conventional post-earnings setup, whereas MRNA and KOD were driven by clinical trial announcements. KOD’s measured continuation also occurred within the same regular trading session rather than across the following session.

They therefore illustrate the broader phenomenon of post-catalyst momentum trading rather than three perfectly identical PEM holding periods.

Conclusion: Big Moves Can Get Even Bigger

MNTN’s November 2026 earnings reaction demonstrates how extraordinary momentum can continue well beyond the initial hourly candle.

After plunging 39%, MNTN produced another 27.34% MFE, experienced just 1.13% MAE, and delivered a hypothetical 26.28% next-day EOD gain for short sellers.

MRNA and KOD demonstrated similar behavior, producing even larger favorable excursions of 64.42% and 80.20%, respectively.

However, our historical research shows that larger initial moves generally produce greater volatility, larger drawdowns, and lower win rates.

The takeaway? Big moves can get even bigger, but they also carry greater risks. Missing the initial earnings candle doesn’t necessarily mean missing the entire opportunity.
