    Aswath Damodaran analyzes the tradeoff between expansion and profitability: the weakest link in venture capital

    Aswath Damodaran, a professor at NYU Stern School of Business, writes that the current venture capital industry generally prioritizes corporate expansion over profitability, a tendency that has become more pronounced over the past two decades. He breaks down six core factors influencing a company's expansion potential, including market size, market growth rate, industry structure, capital intensity, customer inertia, and dependence on key individuals. He also identifies the key variables determining a company's profitability feasibility as unit economics, economies of scale, and competitive barriers.

    AQR Research on Investing in a Warming World: Analysis of Differences Between Mainstream Portfolio Carbon Metrics and Financed Emissions

    AQR has released the research Investing in a Warming World, noting that mainstream portfolio carbon metrics such as carbon footprint and carbon intensity are easily affected by rising stock market valuations, and may show improvement even when corporate emissions change little, potentially overestimating decarbonization progress when used as time-series measures of decarbonization. Financed emissions are more directly linked to real-world emissions outcomes. The study also explores approaches to constructing climate-oriented portfolios, noting that combining multiple metrics can provide a more comprehensive assessment of climate-related investment progress.
