6.1.5 When to Sell
A reasonable time to sell is when the original reason for buying no longer holds, when a fund's process has genuinely deteriorated, when a goal has actually been reached, or when rebalancing calls for it. Selling purely because prices fell is rarely a good reason on its own.
Good reasons to sell
If a fund's investment strategy or management has changed materially since you bought it, if a company's fundamentals have genuinely deteriorated in a way that changes the original investment case, if a specific goal linked to that money has actually been reached, or if rebalancing calls for trimming a position that has grown beyond its target weight, each of these is a legitimate, considered reason to sell.
The question of when to sell is harder than the question of when to buy, because selling involves loss aversion (reluctance to realise a loss), anchoring (comparing to a past high), and the fear of missing out on further gains. Having predefined sell criteria eliminates the need to make this decision emotionally in the moment.
The reason that usually is not good enough on its own
Selling simply because a price has fallen, without any change to the underlying reasoning that led to the original purchase, is frequently a reaction to short-term volatility rather than a genuinely reasoned decision. If nothing about the original investment case has actually changed, a price fall alone is generally not sufficient justification to sell.
Legitimate reasons to sell a mutual fund include: the fund has consistently underperformed its benchmark and peers over a full market cycle (3-5 years), not just a single quarter; the fund manager who built the track record has left; the fund's investment style has drifted from what you originally selected it for; your own goal has been reached and the money needs to be withdrawn or shifted to a safer allocation; or your portfolio needs rebalancing and the equity allocation has grown beyond target.
Illegitimate reasons to sell include: the fund dropped 20% last month (market correction, not a fund-specific problem); a different fund performed better recently (recency bias, not evidence of structural superiority); a finfluencer recommended something else (unverified, unaccountable); or you have a "feeling" the market is going to crash (prediction, not process). Selling based on emotions or short-term noise is the single most common cause of poor investor returns.
A useful check before selling
Before selling, it helps to ask directly: if I did not already own this, would I buy it today at the current price, given everything I currently know? If the honest answer is yes, the original reasoning likely still holds and the fall may simply be normal, temporary volatility. If the answer is genuinely no, that is worth exploring further as a real reason to reconsider the position.
How PriLytics helps. PriLytics shows your goal progress clearly, so you always know whether a specific target has actually been reached before deciding whether it is time to sell. See goals with guidance.
A useful framework: if you would not buy the fund today with fresh money, given what you know now, that is a signal to evaluate whether selling makes sense. If the original investment thesis is intact, the fund is performing within reasonable expectations for its category, and the goal it serves has not changed, holding is almost always the correct action. The tax cost and reinvestment risk of selling create a hurdle: the replacement must be sufficiently better to overcome the cost of the switch, not just marginally different.
