July 2026 Market Conditions: Earnings Fuel Waning, Oil at $95+, and Sector Rotation Underway
JPMorgan warns the S&P 500's 'earnings fuel' is running out as of July 23, 2026 — the PPI-CPI spread has peaked, ISM orders-to-inventory ratio has declined for three consecutive months, and the market is rotating toward defensive assets. Oil surges past $95 on Iran/Hormuz Strait tensions. Core PCE remains sticky at 3.4%, the 10Y yield sits at 4.7%, and the market has begun pricing rate hikes rather than cuts. Small caps have rallied 22% in H1 2026 (best since 1991). Bitcoin is down 31% YTD, Gold down 7% — both declining simultaneously for the first time.
Kyle (1985) - Continuous Auctions and Insider Trading
Kyle's seminal model of informed trading shows how an informed trader strategically splits orders to maximize profit while market makers adjust prices under adverse selection, introducing Kyle's lambda as a measure of market illiquidity.
Glosten & Milgrom (1985) - Bid, Ask and Transaction Prices
The Glosten-Milgrom model explains the bid-ask spread as arising from adverse selection: market makers face a positive probability of trading against informed traders, so they set a spread compensating for the expected loss to informed order flow.
Easley, Kiefer, O'Hara & Paperman (1996) - Probability of Informed Trading (PIN)
Easley, Kiefer, O'Hara and Paperman develop a structural model to estimate the probability of informed trading (PIN) from order flow data, providing an empirical measure of information asymmetry in securities markets.
Fama & French (1993) - Common Risk Factors in Stock and Bond Returns
Fama and French extend the CAPM by adding size (SMB) and value (HML) factors to explain cross-sectional variation in stock returns, demonstrating that the three-factor model explains patterns that the CAPM cannot.
Fama & French (2015) - A Five-Factor Asset Pricing Model
Fama and French extend their three-factor model by adding profitability (RMW) and investment (CMA) factors, providing a more complete description of the cross-section of average stock returns.
Markowitz (1952) - Portfolio Selection (Modern Portfolio Theory)
Harry Markowitz's Portfolio Selection establishes the mathematical foundation for diversification, showing that portfolio risk depends on asset correlations, and introduces the efficient frontier concept.
Sharpe (1964) - Capital Asset Prices: A Theory of Market Equilibrium (CAPM)
William Sharpe's CAPM provides the theory of how assets are priced in equilibrium, showing that expected return is linearly related to systematic risk measured by beta.
Black & Scholes (1973) / Merton (1973) - Options Pricing Model
The Black-Scholes-Merton model provides a closed-form solution for European option prices via a no-arbitrage argument based on continuous delta-hedging, founding the modern options market.
Kahneman & Tversky (1979) - Prospect Theory: Decision Under Risk
Prospect theory describes how people actually make decisions under risk: loss aversion (~2x), reference dependence, and probability weighting. It is the foundation of behavioral finance.
Barberis & Thaler (2002) - A Survey of Behavioral Finance
Barberis and Thaler survey behavioral finance's two pillars: limits to arbitrage (why mispricing persists) and psychology (systematic biases in beliefs and preferences), showing how they explain asset pricing anomalies.
Barber & Odean (2000) - Trading Is Hazardous to Your Wealth
Barber and Odean show that individual investors who trade more frequently earn significantly lower returns, establishing that overconfidence leads to excessive trading which harms portfolio performance.
Shiller (1981) - Do Stock Prices Move Too Much to Be Justified by Subsequent Changes in Dividends?
Shiller demonstrates that stock prices are 5-13 times more volatile than can be justified by future dividends, providing influential evidence against the efficient market hypothesis.
Amihud (2002) - Illiquidity and Stock Returns: Cross-Section and Time-Series Effects
Amihud develops the ILLIQ measure (absolute return / dollar volume) and shows that expected stock returns are positively related to illiquidity across stocks and over time.
Lakonishok, Shleifer & Vishny (1994) - Contrarian Investment, Extrapolation, and Risk
LSV show contrarian strategies outperform because investors extrapolate past growth too far, not because value strategies are riskier. Value stocks do NOT have higher risk in bad times.
Bollen, Mao & Zeng (2011) - Twitter Mood Predicts the Stock Market
Bollen, Mao and Zeng show that the 'Calm' mood dimension from Twitter feeds can predict DJIA movements with 87.6% accuracy, demonstrating the predictive power of social media sentiment.
