Human beings love stories. But this innate tendency can lead us to imagine connections between events where none really exist. For financial journalists, this is a virtual job requirement. For investors, it can be a disaster.
“The Australian dollar rose today after Westpac Bank dropped its forecast of further central bank interest rate cuts this year,” read a recent lead story on Bloomberg.
Needing to create order from chaos, journalists often stick the word “after” between two events to imply causation. In this case, the implication is the currency rose because a bank had changed its forecast for official interest rates.
Perhaps it did. Or perhaps the currency was boosted by a large order from an exporter converting US dollar receipts to Australia or by an adjustment from speculators covering short positions. Markets can move for many reasons.
