Selling is often harder than buying because ownership introduces anchors, attachment, and concern about admitting an error. Review the current thesis for subtle changes before deterioration becomes obvious in headlines or financial results. Treat the original purchase price and prior gains or losses as irrelevant because the market does not incorporate them into the company's present value. When attachment prevents a clean assessment, sell the position to remove the endowment effect and reconsider the company as though encountering it for the first time. The sale need not be permanent: rebuilding a fresh bull and bear case may justify buying again. The framework turns selling from a final judgment into a reversible tool for restoring analytical clarity.

How to run it
- 1
Restate the Thesis
Describe why the company deserves capital today without referring to the original purchase decision.
Pro tip Use current operating evidence and forward expectations.
Watch out Do not defend a stale thesis merely because it once worked.
- 2
Search for Subtle Shifts
Look for early changes in competitive position, management behavior, demand, regulation, or capital allocation.
Pro tip Investigate changes before they become prominent news.
Watch out Waiting for public confirmation can make the eventual exit far more expensive.
- 3
Remove the Price Anchor
Exclude the purchase price, peak price, and desired break-even point from the decision.
Pro tip Ask whether you would buy the same position at today's price with fresh cash.
Watch out The market does not care what you originally paid.
- 4
Sell to Restore Clarity
If ownership is preventing objective judgment, close the position and create psychological distance.
Pro tip Treat the sale as a reset rather than a permanent ban on the company.
Watch out Tax and transaction costs should be considered, but they should not excuse a broken thesis.
- 5
Rebuild Both Cases
Develop a fresh bull case and bear case, preferably with colleagues who hold different perspectives.
Pro tip Assign someone with short-selling experience to challenge the optimistic case.
Watch out Do not recreate the old thesis using different words.
- 6
Reenter Only on Current Merit
Buy again only if present evidence supports an attractive forward return and manageable risk.
Pro tip Set a new thesis and monitoring criteria rather than reviving the old entry record.
Watch out Avoid refusing to rebuy solely because the new price exceeds the old one.
In the wild
A portfolio manager owns a retailer whose margins remain acceptable, but customer retention and inventory quality are quietly deteriorating. Because the original position has been profitable, the manager keeps rationalizing the changes. Selling the position removes the attachment. A fresh review shows the competitive thesis has weakened, so the capital remains elsewhere.
→ The investor exits before the deterioration becomes obvious and avoids anchoring to past success.
Common mistakes
Waiting for the Headline
The best selling opportunities may occur while the evidence is still subtle and before the market fully recognizes the shift.
Anchoring to the Entry Price
Wanting to recover the purchase price or repeat an old bargain distorts the current risk-reward decision.
Treating a Sale as Irreversible
Fear of missing a recovery can delay an exit, even though the position can be repurchased after a clean reassessment.
Is it for you?
Best for
It is best for active investors struggling to evaluate an existing holding objectively.
Not ideal for
It is not ideal for tax-sensitive portfolios when a temporary sale would impose disproportionate costs without improving the decision.
From the transcript
“the best selling happens when things are subtle, not when they are in papers.”
“my view is that cost you bought the stock is irrelevant.”
“I would just sell the stock to clear my own mind, because that this game is played inside, it's not outside.”
