Save The Date: Analyst/Investor Days as a Trading Signal

wp.lancs.ac.uk2026-03-05Paper
Executive summary

A new study finds that Analyst/Investor days, where companies share information, cause sharp stock price jumps, especially when firms hype the event with extra disclosures and insider sales. These hyped events often see prices fall afterward, hinting at short-term inflation and managerial opportunism. Non-hyped events deliver lasting gains, driven by informative Q&A sessions. Using deep reinforcement learning, researchers developed a trading strategy that outperforms traditional models, especially in high-tech firms and positive-toned events.

What it examines

This study examines how companies use Analyst/Investor Days to share information and influence stock prices. It analyzes transcripts from over 1,000 events, investigates pre-event disclosures and insider trading, and tests trading strategies using deep reinforcement learning to see if these events can signal profitable investment opportunities.

What it concludes

The research shows Analyst/Investor Days can be used as trading signals, generating positive returns, especially when combined with smart timing strategies. These findings help investors, analysts, and regulators understand market reactions and improve trading decisions. Future research could explore other event-driven strategies and the impact of disclosure tone.
