By analyzing minute-by-minute Bloomberg terminal usage data from CEOs and CFOs across numerous public firms, they develop a novel proxy for executive work habits. Their findings reveal that increased executive effort correlates with positive earnings surprises, higher cumulative abnormal returns post-earnings announcements, and narrower credit default swap spreads. Moreover, portfolios constructed based on changes in executive effort demonstrate significant risk-adjusted returns, underscoring the tangible value of diligent leadership.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-uncovering-the-hidden-effort-problem\">Uncovering the Hidden Effort Problem<\/h2>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Azi Ben-Rephael,\u00a0Bruce I.

This supports the broader idea behind the&nbsp;<a href=\"https:\/\/alphaarchitect.com\/the-quality-factor-what-exactly-is-it\/\" target=\"_blank\" rel=\"noreferrer noopener\">quality factor<\/a>, which focuses on traits like consistent profitability and operational efficiency\u2014often shaped by effective management.<\/p>\n\n\n\n<p><strong>Market Underreaction to Effort Signals<\/strong>: The persistence of abnormal returns suggests that markets may not fully price in the implications of executive effort, presenting potential opportunities for informed investors.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-practical-applications-for-investment-advisors\">Practical Applications for Investment Advisors<\/h2>\n\n\n\n<p><strong>Enhanced Due Diligence<\/strong>: Incorporating executive effort metrics can refine assessments of management quality, aiding in the identification of firms with proactive leadership.<\/p>\n\n\n\n<p><strong>Portfolio Construction<\/strong>: Strategies that factor in changes in executive effort may capture alpha, as evidenced by the study\u2019s long-short portfolio performance.

When leaders are more engaged, companies often see better earnings and stock performance. By considering the work habits of company leadership, we aim to invest in firms where proactive management drives value, potentially enhancing your investment returns.\u201d<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-the-most-important-chart-from-the-paper\">The Most Important Chart from the Paper<\/h2>\n\n\n\n<p>The figure shows executive platform activity through the quarter relative to the firm\u2019s earnings announcement.

While executives spend most of their time doing other activities, patterns of Bloomberg usage allow us to characterize their work habits as measures of effort provision. We document a positive effect of effort on unexpected earnings and cumulative abnormal returns following earnings announcements, and a reduction in credit default swap spreads. This is robust to using exogenous weather patterns as an instrument. Long-short, calendar-time effort portfolios earn significant average daily returns. Finally, we revisit important agency issues from the literature.<\/p>\n\n\n\n<p><\/p>\n","protected":false},"excerpt":{"rendered":"<p>This study tackles the challenge of quantifying executive
