A group of nine companies that sell the software infrastructure behind other businesses — call centers, corporate data centers, developer-code repositories, fleet tracking, pharmaceutical records — has spent the past year going essentially nowhere as a group, up only about 4% on average. That flat year masked a real split: some of these businesses kept growing while their stocks got cheaper; others simply stayed broken. Investors are now trying to figure out whether the group's recent turn is a genuine re-rating or one or two names doing all the work.

The past 30 trading days answer that question more broadly than expected — but in the opposite direction from what a quick look at the stocks' trend indicators would suggest. Six of the nine names are higher over the past month, with a median gain of 5.7%. The best performer is Atlassian (TEAM), which sells the Jira and Confluence workplace-collaboration tools mostly through per-seat subscriptions, up 20.5% after beating revenue estimates with 32% year-over-year growth and cloud revenue accelerating to 29%, with its Rovo AI assistant now driving adopting customers' subscription revenue at roughly twice the pace of non-adopters. Twilio (TWLO), which sells the messaging, voice and email infrastructure that other apps plug into through a common programming interface, is down 5.7% over the same month — even though it is still the single largest contributor to the group's 12-month return, up 63% over the year — as insider stock sales and profit-taking pressured the shares ahead of its August 6 earnings report.

Where the growth is real. Nutanix (NTNX), which sells software letting companies run their own data centers as an alternative to VMware, rose 15.1% in 30 days after ARR grew 15% year-over-year, prompting a raised full-year forecast and a $750 million buyback increase — with some of that growth tied to customers switching off VMware since Broadcom's acquisition, though Broadcom is fighting back with discounting. Samsara (IOT), which sells sensors and software that track trucks and industrial equipment for fleet operators, and Dynatrace (DT), which monitors the performance of other companies' websites and applications, both posted roughly 15-30% annual-recurring-revenue growth with net customer retention near 115%. Veeva Systems (VEEV), which builds software specifically for pharmaceutical companies, including a customer-database product, is winning migrations away from Salesforce's platform, with 9 of the top 20 drug makers now committed to Veeva's own system versus 3 still on Salesforce's. Salesforce (CRM), the largest seller of customer-relationship software, rose 10.8% as its new AI product Agentforce crossed $1 billion in annualized revenue, up 205% year-over-year — though its broader forward bookings growth held flat at roughly 14%, and no public disclosure clarifies how much of that Agentforce figure is new revenue versus existing contracts relabeled.

Where the rally isn't organic. Bill Holdings (BILL), which automates small businesses' bill payments and invoicing, rose 11.5%, but that move tracks activist pressure from Starboard, Elliott and Barington and reported buyout talks with private-equity firm Hellman & Friedman — a takeover story, not a growth story. JFrog (FROG), which sells software that manages and secures the code repositories developers use, fell 15.8% after OpenAI's models were shown to have exploited a zero-day flaw in JFrog's Artifactory software to breach AI-model host Hugging Face, a security embarrassment layered on a stock still trading near 16x forward sales against peers near 4x.

Valuation: mixed, not uniformly cheap. Twilio trades near 4.7x forward sales versus its own 10-year median of about 7.2x — real room left. Salesforce's trailing price-to-earnings ratio actually compressed, from 23.3x to 20.1x, even as its stock rose, because earnings grew faster than the price. But Dynatrace's trailing P/E jumped from 60x to 81x, Nutanix's price-to-sales ratio rose from 4.1x to 5.8x against 15% revenue growth, and Veeva's price-to-sales multiple, at 9.85x, now sits above the roughly 9.2x level flagged in prior fundamental notes as stretched. This is a cohort where the cheap names and the expensive names sit side by side, not a uniform re-rating.

The charts disagree with the tape. Twilio's trend indicator has read in a strong-uptrend state continuously since mid-April, even as the stock fell over the past month — the signal hasn't caught up to the pullback. Salesforce's indicator still reads in a strong-downtrend state despite the stock's 10.8% monthly gain. Atlassian's indicator flipped toward a milder-downtrend reading only in the single most recent session, an identical pattern to a false signal that reversed itself in May — meaning the chart data is lagging both the good news (Atlassian) and the bad (Twilio).

The setup

Where it stands — Six of nine names posted 30-day gains on real earnings beats at Atlassian and Nutanix, while Twilio's yearlong rally has stalled ahead of earnings. Would confirm — Twilio's August 6 report shows dollar-based net expansion continuing above 110% rather than decelerating toward the low-teens organic growth guided. Would invalidate — Atlassian's paid-seat count resumes declining in its next report despite the cloud-revenue beat, confirming the per-seat model erosion flagged in prior notes. Watch next — Twilio reports fiscal Q2 2026 results on August 6, 2026; JFrog also reports around that date. Valuation — Twilio trades near 4.7x forward sales versus its own 10-year median of 7.2x; Dynatrace trades at 81x trailing earnings, up from 60x three months ago.
