Strategy in a nutshell

This strategy goes long on size- and value-adjusted peers of NYSE stocks that recently announced Strategic Alternatives (SA) and short on the SA stocks themselves. Positions are held for up to three months and rebalanced quarterly.

Economic rationale

Price reversals after SA announcements occur due to “availability heuristics,” where investors overreact to recent M&A news and mispriced fundamentals. The 3-month holding period captures the peak reversal, optimizing returns while avoiding early positive bias or later diminishing effects.
