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