Read the release. Then read the surprise.

Identify the number

Before interpreting a release, check whether it is a level, a growth rate or an index. Note the reference period, release date, seasonal adjustment and revisions. A year-on-year rate and a month-on-month rate describe different comparisons and should not be placed on the same footing without explanation.

Separate nominal from real

In a simplified example, nominal spending grows by 8% while the relevant price index rises by 5%. Dividing 1.08 by 1.05 and subtracting one gives real growth of about 2.86%. Subtracting the two growth rates gives a useful approximation of 3%, but it is not the exact calculation.

The surprise depends on the starting point

A falling inflation rate can still exceed expectations. Market prices can respond to that surprise, to revisions, to the composition of the release or to what it suggests about policy. The same headline number can therefore accompany different market reactions in different settings.

Write conditional scenarios

Build a small dashboard with growth, inflation, policy, credit and currency measures. For each scenario, explain the possible effect on earnings, discount rates, funding and demand across assets. State alternative explanations and identify the next release that could challenge the interpretation.

A learning example, not a market recommendation. Work through the assumptions before applying any model.
