J.K. Lasser’s Buy, Sell, or Hold is a practical guide to portfolio decision-making, focused on the three actions that ultimately define investment outcomes. Michael C. Thomsett approaches investing as an ongoing management process rather than a series of isolated purchase decisions. The book’s central aim is to help investors determine when to act—and when not to—by combining fundamentals, valuation, and disciplined review.
Thomsett frames the “buy, sell, or hold” decision as a structured evaluation of changing conditions. Readers are guided through methods for assessing business performance, earnings sustainability, balance-sheet health, and valuation relative to expectations. Rather than chasing market moves, the book emphasizes aligning portfolio actions with evidence, probability, and long-term objectives.
A distinguishing feature is the emphasis on holding as an active choice. Thomsett explains why many investors underperform by trading too frequently, reacting to headlines, or selling quality assets prematurely. The book details criteria for maintaining positions through volatility, while also defining clear signals that justify trimming or exiting—such as deteriorating fundamentals, valuation extremes, or broken investment theses.
Risk management and portfolio balance are woven throughout. Position sizing, diversification, rebalancing, and review cadence are treated as core competencies. By integrating analysis with disciplined process, Buy, Sell, or Hold equips readers with a repeatable framework to manage portfolios across market cycles without resorting to prediction or speculation.
