Status Quo Bias
Keeping something is a fresh choice disguised as inaction. Ask whether you would buy it again today, under current conditions, to reveal when inertia—not present value—is making the decision.
The stock already in your portfolio is not merely sitting there. Every day you keep it, you are effectively choosing to buy it again at today’s price.
E1Inaction is a hidden transaction
Ownership splits two equivalent decisions into different-looking categories: buying feels active, while holding feels passive. That distinction lets the existing position escape the scrutiny you would apply to a new purchase. The rebuying frame removes the disguise. It converts “Should I continue?” into “Would I choose this now?” and makes current price and current judgment—not the history of ownership—the decision point.
E1Where it shows up
The stock you would not buy
Suppose you would reject a stock at its present price if you held cash, yet continue holding the same stock because it is already yours. The economic choice is unchanged: capital remains allocated to that stock. What changes is only the label placed on the decision.
E1A diagnostic, not a verdict
The rebuying question exposes inconsistent reasoning; it does not establish that selling is correct. You may still lack information, face practical constraints, or rationally prefer a sufficiently good existing option over a costly search for the best one—an instance of Bounded Rationality.
Turn the holding into an order
Tomorrow, take one investment you already own and write down its current value. Then ask: “If this amount were cash in my account, would I place a buy order for this stock at today’s price?” If the answer is no, require yourself to state a present-tense reason for continuing to hold it.
