When to Trim, When to Hold

Selling is harder than buying. It requires admitting a thesis has drifted, or that a position has grown too large to ignore.

My default is to hold. Compounding works best when you don't interrupt it, and most trimming decisions I've made were about my own discomfort, not about the business.

The two reasons that pass the test: the thesis is genuinely broken (the moat narrowed, the management changed, the economics reversed) or the position has become so large that one bad outcome would be irrecoverable. Neither is about the stock being 'expensive.'
