Important Market News Is Not Necessarily Actionable

Swedroe distinguishes information that affects prices from information an ordinary investor can profitably trade. Economic releases matter to markets, but the rapid adjustment of prices and poor evidence for successful market timing make immediate portfolio changes unlikely to help.

  • Economic data can materially affect stock and bond prices.
  • Importance does not imply a profitable trading opportunity.
  • Exploiting public releases requires successful market timing.
  • Very few investors demonstrate persistent success at such timing.

“It clearly is important, but that doesn't mean you should do anything about it”

Larry Swedroe · 04:05

“there's very, very very few people who have been successful doing it.”

Hot Take04:44

The Financial Media's Incentives Conflict With Investor Discipline

The discussion argues that financial media benefits when investors perceive every release as urgent. Countdown clocks, dramatic coverage, and emotional framing attract attention and advertising revenue, but they can encourage behavior that conflicts with a long-term investor's interests.

  • Urgency keeps audiences watching.
  • Fear and excitement increase investor engagement.
  • Advertising incentives reward attention rather than portfolio discipline.
  • Investors should distinguish media importance from investment relevance.

“The media plays on these fears and emotions.”

Larry Swedroe · 05:08

“That's how they make money selling those commercials while you're watching. But that's not in your interest.”

How Political Identity Changes Investor Behavior

Political alignment can affect confidence during crises. Investors may remain disciplined when their preferred party governs but become pessimistic and sell when the opposing party is in power, producing different realized returns even when they face the same market.

  • Political confidence can alter perceptions of economic risk.
  • Partisan pessimism may prompt panic selling.
  • Partisan optimism may help investors remain invested through declines.
  • Diversification is more reliable than forecasting election outcomes.

“you want to make sure you do not let your political biases influence your investment decisions.”

The Small Exception: Post-Earnings Announcement Drift

Swedroe acknowledges evidence that prices can continue moving after an unexpected earnings result, a phenomenon called post-earnings announcement drift. However, because sophisticated practitioners know the effect and appear to be arbitraging it away, he still advises most investors not to trade on it.

  • Unexpected earnings can be followed by short-term momentum.
  • Investors may initially underreact to an earnings surprise.
  • The effect is widely known among finance professionals.
  • Its exploitable strength appears to be shrinking.
  • The default advice remains to avoid trading.

“There is some evidence here to support the idea that when there are positive or negative earning surprises is called the peed factor post.”

Larry Swedroe · 10:25

“So my advice is you're probably best off just to ignore it and don't trade.”

Why Republicans and Democrats Outperform at Different Times

Swedroe describes research in which Republican investors performed better during Republican administrations while Democratic investors did better under Democratic presidents. The proposed mechanism is not superior forecasting but greater confidence in a favored administration, making those investors less likely to sell during a crisis.

  • Republicans were more inclined to stay invested under Bush and Trump.
  • Democrats showed greater confidence during the Obama administration.
  • Remaining invested allowed investors to participate in market rebounds.
  • Behavior, rather than political forecasting skill, explains the effect.

“They were more likely to stay the course uh, and therefore they were able to gain the rebound in the market”

Larry Swedroe · 09:43

“the reverse was true when Obama was president.”

Q&A06:57

Should Shareholders Trade When Activists Target a Company?

Asked how holders of companies such as Disney, Apple, or Tesla should respond to activist campaigns, Swedroe recommends no immediate action. Professional investors are already evaluating the same development, and their collective trading incorporates the information into the current price.

  • Activist campaigns are quickly visible to professional investors.
  • Current prices aggregate many competing assessments.
  • An individual investor is unlikely to react before the market.
  • Persistent active-manager underperformance weakens the case for trading the news.

“I would suggest nothing, because the markets already incorporated that information into prices.”

Larry Swedroe · 07:14

“Over ninety percent of the active managers underperform over the long term in every single asset class, and that's even before taxes.”

Takeaway11:26

Distractions Are a Normal Cost of Long-Term Investing

The episode closes by treating earnings reports, economic releases, geopolitics, and analyst calls as unavoidable distractions rather than reliable forecasts. Investors lack special insight into both how events will unfold and how prices will respond, so remaining invested is presented as the strongest default.

  • Long investment horizons inevitably include alarming developments.
  • Knowing an event does not reveal its future price impact.
  • Analyst and corporate news provide no automatic edge.
  • Staying invested protects the long-term plan from reactive decisions.

“none of us have any extra insight as to how those events will unfold and how they'll impact stock prices in the future.”

“Your best bet stick with stocks for the long haul and ignore the noise.”
