Key takeaways
- Bloom Energy reports on October 22, with options pricing pointing to a potentially large move in either direction.
- Supermicro has already raised its preliminary revenue and margin estimates; its November 3 report will test that stronger starting point.
- Sandisk on October 29 and 10x Genomics on November 5 offer different checks on whether demand is translating into profitable growth.
Wednesday’s market is giving earnings-sensitive stocks a constructive backdrop. Around 12:05 ET on October 21, the S&P 500 was up 0.51%, the Nasdaq Composite gained 1.09% and the PHLX Semiconductor Index rose 2.00%. These are intraday changes from Tuesday’s close, not final session returns.
Bloom Energy, Supermicro and 10x Genomics were outperforming that broader advance, while Sandisk was also higher. The opportunity is to see whether the coming reports support this renewed interest. Each company faces a different test: power-system execution, AI-server profitability, memory pricing or research-tool demand.
Bloom Energy: tomorrow’s report tests the power-demand story
At 12:05 ET, Bloom Energy (BE) traded at $238.14, up 6.96%. The company has scheduled its third-quarter 2026 results after the October 22 close, followed by a 17:00 ET call. Bloom’s announcement makes this the nearest earnings event among the four.
An October 21 TipRanks preview cited expectations of $1.07 billion in revenue and $0.69 in adjusted earnings per share, alongside a 10.7% options-implied move. Those are the publisher’s dated estimates, not company results. The implied move describes potential movement in either direction; it does not forecast a 10.7% gain or place a limit on the eventual reaction.
Bloom’s July 28 results reported $1.065 billion of second-quarter revenue and raised full-year revenue guidance to $3.9 billion–$4.2 billion. That earlier performance gives tomorrow’s report a demanding reference point. Watch whether installations and customer commitments convert into revenue and operating cash, and whether management maintains or improves the annual outlook. Strong demand is more valuable when delivery, margins and cash collection improve together.
Supermicro: a stronger preview raises the bar for November
Supermicro (SMCI) was at $35.61, up 9.67% around 12:05 ET. Its October 20 preliminary update estimated fiscal first-quarter 2027 revenue of $18.5 billion–$19.5 billion, compared with earlier guidance of $14.5 billion–$15.5 billion. Estimated gross margin rose to 12.0%–12.5%, from 10.4%–10.8%. Management attributed the stronger revenue estimate to AI-platform demand and the margin improvement to customer and product mix. The figures remain unaudited and subject to revision. The results call is scheduled for November 3 at 17:00 ET.
This is a follow-through test: can final figures substantiate the improved estimates, and can new guidance sustain that momentum? Cash flow, receivables and inventory will help explain the quality of the growth.
The advance also extended across server peers: around the same time, Dell gained 4.91% and HPE rose 3.18%. That suggests wider interest in the group, although Supermicro’s update does not establish what either peer will earn.
Sandisk: October 29 puts pricing and margins in focus
Sandisk (SNDK) traded at $1,384.50, up 1.40% around 12:05 ET. Its fiscal first-quarter 2027 earnings call is confirmed for October 29 at 16:30 ET, according to the company’s schedule.
In its August 5 outlook, Sandisk guided to quarterly revenue of $10.30 billion–$10.80 billion and non-GAAP diluted earnings per share of $44–$46. These are management’s earlier forecasts, not newly reported results or a current analyst-consensus estimate.
The useful questions are how much growth comes from shipment volumes versus pricing, whether higher-value data-center products improve the mix, and how durable margins appear in the next outlook. A strong quarter would support the memory-demand story. For the share price, the further test is whether forward guidance meets the expectations investors have built into the rally.
10x Genomics: November 5 tests recurring demand beneath the rebound
10x Genomics (TXG) was at $77.09, up 7.88% around 12:05 ET. The company’s October 13 announcement schedules third-quarter 2026 results after the November 5 close, with a 16:30 ET webcast.
This is a life-science research-tools business, so its operating drivers differ from those of the AI-infrastructure companies. In its August results filed with the SEC, 10x reported second-quarter revenue of $151.0 million and raised full-year revenue guidance to $610 million–$630 million. Excluding non-recurring settlement revenue from both comparison periods, quarterly revenue increased 3% year over year.
Watch instrument placements, recurring consumables demand and spending discipline. New-platform orders can build an installed base; continuing usage is what can turn those placements into repeat revenue. Separating underlying sales from settlement effects will make the next report easier to assess. Evidence of stronger adoption and an improving outlook would give the rebound firmer business support.
What to watch through the close and the reporting dates
For today’s session, the first check is whether these stocks retain their relative strength as the broader market trades into the close. An intraday gain is encouraging, but it does not resolve the earnings questions ahead.
The calendar then moves from Bloom on October 22, to Sandisk on October 29, Supermicro on November 3 and 10x Genomics on November 5. Across all four, compare the results with the appropriate reference—analyst expectations, prior company guidance or a preliminary update—and then read the new outlook. Improving margins, cash generation and credible forward demand would give the rally more support than a headline revenue beat alone.
