According to @QCompounding, Phil Fisher stated that if the purchase analysis is correct, the time to sell a common stock is almost never, emphasizing a buy-and-hold, low-turnover approach; source: @QCompounding, Twitter, Jan 5, 2026. For traders, this underscores rigorous entry due diligence and holding through volatility unless the original thesis breaks, making selling the exception rather than the rule; source: @QCompounding, Twitter, Jan 5, 2026.

According to @QCompounding, Phil Fisher is quoted as saying that if the purchase work is done correctly, the time to sell a common stock is almost never (source: https://twitter.com/QCompounding/status/1989286502648394016). For trading, this principle supports a low-turnover, thesis-driven approach where exits are tied to fundamental deterioration rather than short-term price swings (source: https://twitter.com/QCompounding/status/1989286502648394016). Actionable takeaway: after rigorous research and a high-conviction entry, default to holding and reassess only if the original investment case breaks or the quality of the business declines (source: https://twitter.com/QCompounding/status/1989286502648394016).
