THE PERIMETERReviewed September 19, 2026Guide · Questions · Checklist

The most useful response to a market headline starts with your exposure, your time horizon and the job each asset performs. A price move is information; it is not, by itself, a reason to trade.

Separate the headline from the holding

Identify which businesses, sectors, currencies or maturities you actually own. A familiar index can behave differently from your portfolio. Look through funds and employer stock for overlapping exposures before drawing conclusions.

Put liquidity before forecasts

List spending, tax payments and commitments that may require cash. Then compare those dates with the assets you would need to sell. A long-term allocation should not depend on selling an illiquid asset on a particular day.

Compare the whole decision

For a proposed change, examine transaction costs, tax consequences, the risk you remove and the risk you add. Write down what evidence would make you reverse the decision. Rebalancing rules are more useful when decided before a volatile day.

Four questions for a better conversation

  1. What percentage of my wealth depends on the same company, industry or economic outcome?
  2. Which spending needs must be funded without relying on favorable market prices?
  3. How does the proposed allocation behave in a recession, an inflation shock and a recovery?
  4. What are the all-in fees, tax consequences and implementation costs?
