3 Stocks With Accelerating Earnings Poised to Soar in October

A Zacks earnings-acceleration screen narrowed roughly 7,735 stocks to 16 candidates and highlighted Western Digital, PACCAR and Sprout Social as October buy ideas, each carrying a Zacks Rank #2 (Buy). Estimated current-year earnings growth is 96% for Western Digital, 37.8% for Sprout Social and 18% for PACCAR. The thesis is that accelerating quarter-over-quarter EPS growth could precede stock-price appreciation, though the article provides no new company disclosures or revisions to consensus estimates.

Analysis

This is a low-information screen rather than a new fundamental catalyst; the highest-probability near-term effect is marginal retail/quant flow, not a durable estimate reset. Treat any immediate strength as an opportunity to validate whether sell-side next-twelve-month EPS has actually moved higher and whether revisions are broad-based. Without upward revenue estimates and management guidance, reported EPS acceleration can reflect trough comparisons, buybacks, or temporary gross-margin recovery rather than incremental intrinsic value.

WDC is the most actionable of the three because storage earnings have high operating leverage to cloud-capex demand and NAND/HDD pricing, but it also has the greatest cycle risk. A sustained recovery would favor HDD-component and equipment beneficiaries such as STX and, indirectly, storage-capex suppliers; conversely, hyperscaler capex moderation or renewed NAND price competition would compress the recovery multiple quickly. Over 6-18 months, the key question is whether AI data-center architecture produces structurally higher nearline-HDD demand rather than merely a cyclical inventory refill.

PCAR's earnings trajectory is more likely to be challenged by a maturing freight cycle, dealer inventory normalization, and residual-value pressure than captured by a backward-looking acceleration signal. For SPT, the relevant catalyst is net-revenue retention and enterprise-seat growth; AI-enabled workflow features can support pricing, but the larger platforms—CRM, HUBS, META and GOOGL—retain distribution and bundling advantages. Consensus may be underestimating WDC's cyclical upside if storage pricing holds, while over-crediting PCAR and SPT for earnings momentum absent forward estimate revisions.

Key Decisions for Investors

• Watch, do not chase, WDC on screen-driven strength. Initiate a 1-3 month long only after upward next-quarter revenue/EPS revisions and stable storage pricing are confirmed; use a 7-10% stop or exit on a guidance reduction. Preferred expression: long WDC versus short STX only if WDC's estimate revisions exceed STX's, as this isolates relative recovery execution.
• For 3-6 months, consider PCAR underweight versus XLI if North American Class 8 orders and dealer inventories deteriorate; the trade is invalidated by a clear order-book reacceleration or improved 2027 freight-rate expectations. Avoid shorting solely on the screen signal because parts and financial-services earnings can cushion truck-cycle weakness.
• Keep SPT on an earnings watchlist rather than establish a position. Upgrade to a long only if net-revenue retention, enterprise additions, and free-cash-flow margin all improve concurrently at the next report; failure to demonstrate those metrics would make a post-screen rally a candidate for a tactical short against HUBS.
• Set an alert for material changes in consensus FY EPS and revenue estimates across all three names: a minimum 3-5% upward 60-day revision supports momentum follow-through; flat estimates despite price gains signals multiple expansion and favors taking profits within days to weeks.
