NEW YORK, October 18, 2026 — Financial newsletter TKer marked its fifth anniversary Sunday with a special edition examining one of the most consequential contradictions in the U.S. stock market: investors can correctly predict that equity valuations will decline and still be wrong about the direction of stock prices. Founder Sam Ro used the publication’s latest annual review to explain how strengthening corporate earnings expectations have enabled the S&P 500 to rise even as its forward price-to-earnings ratio has contracted.

The analysis comes at a particularly sensitive moment for Wall Street. U.S. stocks have experienced renewed volatility amid concerns about inflation, borrowing costs and the sustainability of artificial-intelligence investment. Yet the longer-term performance of major equity benchmarks continues to demonstrate how corporate profit growth can offset pressures that might otherwise weigh on valuations.

According to TKer, the S&P 500 advanced approximately 16% during the newsletter’s fifth year despite entering the period with an unusually elevated forward price-to-earnings ratio near 23. Such a valuation suggested investors were paying historically high prices for expected future profits, raising concerns that any reduction in market optimism could produce disappointing returns.

Instead, earnings expectations continued to improve. Corporate profits and analysts’ projections rose sufficiently to support higher share prices even as the multiple investors were willing to pay for each dollar of expected earnings declined. The outcome forms the basis of the latest installment in TKer’s series of stock-market principles, which emphasizes that valuations have limited power to predict returns over short investment horizons.

The underlying financial relationship is straightforward. A price-to-earnings ratio compares a stock’s market price with its earnings, or expected earnings when using a forward measure. If earnings forecasts increase faster than stock prices, the resulting ratio declines even when the market itself advances. Conversely, a valuation multiple can increase during a market decline if earnings expectations deteriorate even more sharply than prices.

This mathematical distinction helps explain why seemingly contradictory market forecasts can both contain elements of truth. A strategist predicting lower valuation multiples may accurately identify a future change in market pricing relative to profits. But an investor translating that forecast directly into an expectation of falling share prices could reach an incorrect conclusion.

TKer’s anniversary edition places the development within a broader five-year history of changing market conditions. The newsletter launched on October 14, 2021, shortly before U.S. financial markets entered a challenging period characterized by accelerating inflation, rising interest rates and deteriorating investor confidence.

During TKer’s first year, the S&P 500 declined approximately 19% as the Federal Reserve aggressively tightened monetary policy to confront inflation. Higher interest rates increased the appeal of fixed-income investments and reduced the present value investors assigned to future corporate earnings, particularly for companies whose valuations depended heavily on expectations of substantial long-term growth.

The newsletter’s second year coincided with a recovery in equity markets, with the benchmark advancing approximately 21%. Its third year produced an even stronger gain of about 35%, demonstrating the speed with which investor expectations can change when economic conditions and corporate profitability prove more resilient than anticipated.

During the fourth year, the S&P 500 added approximately 14% despite substantial political and economic uncertainty. TKer identified trade disputes, tariff developments, currency volatility, geopolitical tensions and concerns about Federal Reserve independence among the challenges confronting investors during that period. The market nevertheless recorded repeated highs, supported in part by resilient corporate earnings.

The fifth year presented a different valuation challenge. Stocks were already trading at elevated multiples, creating a debate among Wall Street strategists about whether those levels could persist. Some analysts argued that stronger corporate profitability justified maintaining premium valuations, while others warned that expensive shares faced an increasing risk of multiple contraction.

The actual outcome illustrated the limitations of treating those arguments as mutually exclusive forecasts of price direction. Valuations contracted, but the broad market still advanced over the anniversary period. Rising earnings estimates helped reconcile what otherwise appeared to be conflicting market signals.

Fresh research from FactSet reinforces the importance of the earnings component. In its October 16 earnings-season update, the financial-data provider reported that the S&P 500’s forward 12-month price-to-earnings ratio stood at 19.0, below its five-year average of 19.8 and its 10-year average of 19.1.

The same report showed that analysts and companies were still projecting substantial earnings growth. The blended year-over-year earnings growth rate for the third quarter was estimated at 29.0%, combining actual results from companies that had already reported with projections for those yet to announce results.

FactSet reported that 9% of S&P 500 companies had released third-quarter results by October 16. Of those companies, 84% had reported earnings per share above analyst expectations, exceeding the five-year average of 78% and the 10-year average of 77%.

However, the magnitude of those earnings surprises provided a more qualified picture. Companies were exceeding aggregate earnings estimates by 2.6%, substantially below the five-year average surprise of 7.5%. That distinction indicates that while positive earnings announcements remained widespread, the degree of outperformance was less impressive than historical norms.

The third-quarter growth estimate had also slipped from 29.4% a week earlier. FactSet attributed part of the reduction to downward revisions for healthcare companies, partly offset by improving expectations in the energy sector. The findings demonstrate that stronger overall earnings expectations do not necessarily translate into uniformly improving conditions across the corporate economy.

Analysts nevertheless expected earnings growth of 28.6% for the fourth quarter and 32.8% for the full 2026 calendar year, according to FactSet’s October 16 report. Those forecasts remain subject to revision as companies disclose financial results, provide guidance and respond to changing economic conditions.

The distinction between market valuations and market performance has particular implications for technology investors. Artificial-intelligence infrastructure spending has become an important contributor to expectations for revenue and earnings growth across semiconductors, data-center equipment and related industries. However, companies benefiting from strong demand can still experience volatile share prices when interest rates rise or investors reassess the sustainability of future profits.

MarketWatch reported October 18 that Wall Street was approaching a critical confrontation between powerful corporate earnings growth and higher borrowing costs. The report highlighted how technology and energy companies were benefiting from strong profit expectations even as rising bond yields challenged the valuations investors were prepared to support.

For investors in technology-heavy portfolios, the interaction matters because expectations about future profits and the discount rates applied to those profits can change independently. A company may deliver stronger earnings while its stock falls because investors become less willing to pay a premium. Alternatively, higher earnings forecasts can outweigh a declining valuation multiple and sustain price appreciation.

TKer’s analysis also coincided with a recent setback for U.S. equities. The S&P 500 fell 1.9% during the week ending October 16, closing at 7,659.44, according to the newsletter’s market review. That left the benchmark 2.0% below its October 6 closing high of 7,818.93, although it remained 14.1% higher for the year.

The contrast between the week’s decline and the broader annual gain illustrates another element of the newsletter’s argument: short-term corrections can occur within longer market advances. Neither a temporary selloff nor a historically expensive valuation is sufficient, by itself, to establish the direction of future returns.

Ro’s anniversary edition also examined the underlying strength of the U.S. economy. The newsletter highlighted continuing consumer spending, resilient corporate balance sheets and sustained business investment alongside persistent inflation, elevated energy costs and borrowing rates that remain challenging for households and businesses.

These economic crosscurrents can influence both sides of the valuation equation. Consumer demand and business investment support corporate revenue, while inflation and higher financing costs can constrain margins and reduce the amount investors are willing to pay for anticipated profits. Their combined effect is rarely captured adequately by a single valuation indicator.

In addition to its investment analysis, the anniversary edition provided an update on TKer as an independent financial-media business. Ro reported that the newsletter now reaches more than 36,000 subscribers across all 50 U.S. states and 177 countries, reflecting growing demand for market commentary aimed at long-term investors and financial professionals.

The publication also disclosed that paid subscription revenue reached a record in July before growth plateaued. Ro attributed part of the slowdown to relatively calm market conditions, observing that audience interest in financial commentary often strengthens when equity markets become more volatile or experience substantial declines.

The development offers a secondary business perspective on the financial-information industry. Independent investment publications increasingly operate through direct reader subscriptions, making audience retention, perceived credibility and differentiated analysis important factors in commercial sustainability. TKer’s stated strategy places particular emphasis on maintaining its editorial approach rather than changing its content solely to accelerate subscriber growth.

For the broader investment community, the more immediate test will come as additional companies report quarterly results. FactSet said 79 S&P 500 companies were scheduled to announce third-quarter earnings during the coming week, potentially providing new evidence about whether elevated profit-growth expectations remain justified.

Those results could influence both the earnings forecasts used to calculate forward valuations and investor confidence in paying existing multiples. Stronger-than-expected results may support equity prices even if valuation ratios remain under pressure. Disappointing profits, by contrast, could expose stocks to simultaneous earnings downgrades and multiple contraction.

TKer’s fifth-anniversary assessment does not establish that expensive markets are safe from major declines or that rising earnings will always offset tighter financial conditions. Its more limited conclusion is that valuation measures, although useful for evaluating longer-term investment opportunities, cannot reliably determine the timing or direction of market moves over the next year.

As U.S. companies enter a busy earnings-reporting period, that distinction remains particularly relevant. Investors confronting strong profit forecasts, changing interest-rate expectations and renewed market volatility face a problem that cannot be resolved through valuation multiples alone: accurately assessing what stocks are worth is not the same as knowing where their prices will trade next.
