Behaviour

Financial news is published daily whether or not anything happened

The volume of market coverage is set by a publishing schedule, not by the amount of genuinely new information. The two are unrelated.

General information. This is journalism, not personalised financial advice. Figures, rates and rules change and vary by country — check current terms before acting. How we work.

What follows is an argument about following financial news, and about where the received version of it stops being true.

The argument in brief

  • Output volume is fixed by the schedule, not by how much actually changed.
  • Explanations for market moves are chosen after the move, from several candidates.
  • Match reading frequency to decision frequency, not to publication frequency.

Supply is fixed, information is not

A financial news operation produces roughly the same quantity of output every day regardless of how much genuinely changed. On quiet days that space gets filled with explanation, prediction and commentary rather than with anything that happened.

Readers cannot easily separate the two, because both arrive in the same format carrying the same apparent authority. The result is a steady stream of material that feels like information and is mostly not actionable for a long-term holder. This is a structural feature of publishing rather than a failing of any particular outlet or any particular journalist.

Explanations are generated after the fact

Market moves are routinely attributed to a cause identified afterwards, because a story requires a reason and a move without one is unpublishable. The same day's movement could usually be attributed to several different candidate causes, and the chosen one is the most convenient narratively.

Put simply, this produces a false sense that markets are legible and that following the coverage confers genuine understanding. It also trains readers to expect that every move has a reason they might have anticipated, which quietly encourages action. A daily explanation habit is therefore not neutral, because it slowly builds the belief that you ought to be doing something.

What is actually worth reading

Company reports, fund annual reports and regulatory documents contain information that has not been pre-digested on your behalf. Long-form analysis that survives being read a year later is usually about mechanisms rather than about last week.

Anything explaining how something works is far more durable than anything explaining what has just happened. Reading less and reading slower tends to produce better decisions than reading more, which is an uncomfortable conclusion about a media habit. Nothing here recommends ignorance; it recommends matching the frequency of your reading to the frequency of your decisions.

The urgency signal

Headlines are written to be clicked, and manufactured urgency is the most reliable device available for that purpose. Words like plunge, surge and warning are doing emotional work rather than describing any magnitude with precision.

For most people, a fall described dramatically is frequently a routine movement that would have gone unremarked in a calmer stretch. Checking the actual percentage rather than the adjective is a small habit that defuses most of this immediately.

The strength of your reaction to a headline is a measure of the headline, not of the event it purports to describe.

Setting a consumption rule

Decide in advance how often you will read about markets, and hold that frequency regardless of what is currently happening. The rule matters most during turbulent periods, which is precisely when consumption naturally rises without anybody deciding to increase it.

Where it helps most, removing notifications and app badges achieves more than any amount of intention, because it changes what reaches you unprompted. Some people find a weekly or monthly summary entirely sufficient, and very few find they missed anything that demanded action. A rule set while calm is worth considerably more than a judgement made while the market is falling.

None of this is a substitute for talking to a clinician if something feels wrong.

What to do with the impulse to act

Write down the trade you feel like making, together with the reason and the date, then do nothing for a stated period. Most of those notes read as embarrassing within a few weeks, and your own record is more persuasive than any general advice. If the impulse survives the delay and still fits the written plan, it was probably not a reaction to a headline.

This costs almost nothing, because the cases where the delay proved expensive are outnumbered by the cases where it saved money. The delay is not a prediction about markets; it is a filter applied to your own reactions.

The takeaway

The schedule decides how much gets published. Your plan decides how much of it matters.

The version you keep doing is the version that works.

Questions readers ask

Should I stop reading about markets entirely?

Not necessarily. The useful change is usually frequency and format: less daily commentary, more material about mechanisms that is still true a year later.

How do I know if a headline matters?

Ask whether it changes anything in your written plan. Almost nothing does, and that question takes seconds to answer honestly.
