One week, three very different readings

The Cboe Volatility Index closed at 17.49 on Wednesday, a 10.12% drop from Tuesday and about 38% below its Nov. 5 close of 28.18. That earlier close followed a 69.66% one-day jump from 16.61. The two ends of the sequence tell different stories about the same week. A client who called on Thursday was looking at a spike. A client who waited until Wednesday was looking at a reading closer to where it started.

The VIX is an annualized estimate of expected S&P 500 volatility over the next 30 days, drawn from options prices. The number conveys the size of the swings investors are pricing. An options market can price larger moves in either direction, and a Canadian client's portfolio can behave differently depending on its mix of assets, currency exposure and cash needs.

The index fell in four successive sessions after Nov. 5. It expresses annualized expected S&P 500 volatility over the next 30 days.

The timing of feedback changes the decision

In a 1997 experiment, economists Uri Gneezy and Jan Potters found that participants took less risk when they evaluated their returns more frequently. The result fits myopic loss aversion, the idea that frequent evaluation gives investors more occasions to experience losses and that those losses carry disproportionate weight. A screen checked every hour can produce many more chances to reconsider an allocation than a scheduled review built around what the money is meant to do.

That finding offers a framework for discussing the week. The VIX records options prices and the experiment records behaviour under controlled conditions. A client who reduced exposure on Nov. 5 might have been responding to a real change in circumstances, such as an unexpected expense or a retirement date brought forward. Asking what changed in the household is how an adviser distinguishes a change in capacity from a change in how the same capacity feels.

A useful prompt is to have the client write down, before looking at another quote, what they would need to know to justify a trade. The answer could be a portfolio weight outside its policy band, a near-term withdrawal that is no longer covered, or a planned purchase that will require cash sooner. Those criteria can be checked even when the market is closed.

Put the review date and the action threshold in writing

The review can run on two clocks. Near-term bills and withdrawals deserve frequent checks because dates and amounts are known and the consequences of a shortfall are immediate. Long-term equity exposure can be reviewed at agreed intervals and whenever an allocation band or a material life event triggers action. An adviser can write both rules in plain language and share the dates with the client.

That gives Wednesday's lower VIX a practical use. It creates a quieter occasion to revisit the conversation that Thursday's jump may have started. Ask which decision was on the table, what evidence the client relied on and whether it changed the plan. If exposure was reduced, agree on the conditions for reviewing the cash position, including when the review will happen. The point of writing down a condition now is that the next decision can use the same test, regardless of the number on the screen.
