The Product-Killing Machine
When Wall Street analysts stop watching a company, something curious happens: the company stops cutting products. This counterintuitive pattern, revealed through analysis of millions of Amazon customer reviews across thousands of firms, exposes a hidden mechanism driving what appears on store shelves and website catalogs. The research, published June 2 in The Accounting Review by Cornell professor Eric Yeung and colleagues, used a natural experiment to isolate the effect: when brokerage mergers or shutdowns reduced analyst coverage of certain companies, those firms became less likely to eliminate non-core products, according to the study.
The implication is stark. Product strategy at major corporations isn't primarily shaped by customer demand, competitive positioning, or managerial vision. It's shaped by quarterly earnings pressure transmitted through analyst expectations. Wall Street has become an automated product-elimination system, operating largely outside public view.
How the Machine Operates
The mechanism works through a predictable sequence. When companies face tight earnings results, they respond by cutting back on weaker, non-core products while protecting their strongest offerings, according to research from Cornell SC Johnson College of Business. This isn't across-the-board cost reduction. It's strategic amputation designed to improve financial optics.
The data reveals the precision of these cuts. Core products, defined as those customers buy repeatedly, rate highly, and associate with the firm's brand, hold steady even under earnings pressure, per the study. Non-core products under the same pressure are more likely to receive lower ratings and disappear from the market in following years. The ratings decline isn't driven by deteriorating quality across the board. It's driven by the systematic removal of products serving smaller customer segments.
The reward loop completes the circuit. Firms that just meet or beat earnings expectations often receive higher stock returns in the following year, with gains concentrated among companies that divest from non-core products, according to the research. The market notices which companies are "sharpening their focus" and prices in the approval.
The Weak-Incentive Amplifier
The system doesn't affect all companies equally. The refocusing effect is especially strong in companies with weaker managerial incentives, where CEOs own less stock or lack compensation structures rewarding long-term performance, per the study. This finding reveals something uncomfortable: when executives have less personal stake in the company's future, they're more responsive to short-term market pressure.
The pattern suggests these cuts aren't primarily strategic decisions made by confident leaders with long-term vision. They're survival responses made by executives whose compensation structures align them more closely with quarterly stock movements than with five-year product roadmaps. The weaker the CEO's long-term incentives, the more aggressively they wield the axe on non-core offerings.
What the System Can't See
The products disappearing under this pressure aren't necessarily failing in the market. They're failing to meet the threshold of importance that justifies their existence during an earnings squeeze. A product might serve a loyal niche customer base, generate modest but stable revenue, or represent an experimental entry into an adjacent market. None of that matters if it's classified as non-core when the quarterly numbers come up short.
The Amazon data, representing thousands of firms and millions of consumer reviews analyzed by the researchers, captures the moment of disappearance but not what's lost. The system optimizes for financial clarity, not for the full range of customer needs or for the option value of maintaining diverse product portfolios. It creates a marketplace where only blockbusters and core offerings survive sustained earnings pressure.
The analyst coverage finding provides the clearest evidence that external market pressure, not internal strategic judgment, drives these decisions. When that external pressure drops due to analyst coverage reduction from brokerage mergers or shutdowns, companies become less likely to cut back on non-core products, according to the study. The products don't suddenly become more strategically important. The surveillance simply decreases.
Strategy or Automation?
Corporate communications invariably frame these cuts as "strategic refocusing" or "returning to core strengths." The language implies deliberate choice, careful analysis, and confident leadership. The data suggests something closer to an automated response to external stimuli. Earnings pressure goes up, non-core products go down. Analyst coverage drops, product cuts decrease. The correlation is mechanical.
This doesn't mean the cuts are irrational from a stock price perspective. The market rewards them, at least in the short term. But it raises questions about who's actually making product strategy decisions at major corporations. If the same external pressure produces predictable internal responses regardless of industry, customer base, or competitive position, then the locus of control has shifted from the executive suite to the analyst call.
The pattern fits a broader trend of systematic decision-making replacing human judgment in consequential domains. Algorithms screen job candidates, credit scores determine loan access, and now quarterly earnings pressure functions as an invisible product portfolio manager. Each system operates according to clear rules and produces measurable outputs. Each also makes decisions that affect millions of people based on optimization criteria that may not align with the full complexity of human needs.
The Homogenization Engine
The long-term effect is a marketplace increasingly dominated by core products that survive repeated earnings squeezes. Experimental offerings, niche products, and items serving smaller customer segments face structural disadvantage. They're the first to go when the numbers tighten, regardless of customer satisfaction or long-term potential.
Eric Yeung is a professor of accounting at the Samuel Curtis Johnson Graduate School of Management at Cornell, where this research originated. The study included co-authors Xingyu Shen, a doctoral candidate at University of Rochester, and Jiawen Yan, now a professor at National University of Singapore. Their work reveals a machine that's been running for years, making consequential decisions about what products exist in the marketplace, operating largely without public discussion of its mechanisms or effects.
The question isn't whether earnings pressure sometimes prompts useful strategic refocusing. It's whether an automated system driven by quarterly stock price concerns should function as the primary arbiter of product strategy across thousands of companies. The data shows it already does. Whether that serves customers, innovation, or long-term value creation remains an open question, one the market's reward structure isn't designed to answer.
