The answer says the trader is following a systematic strategy because they are using “rules”. However, the case indicates the trader is using research on inflation. Discretionary trading as defined by CFA Vol 5, page 92 includes: “Discretionary trading strategies trade financial, currency, and commodity futures and options. Unlike systematic strategies, they involve portfolio manager judgment. Discretionary trading models include those based on fundamental economic data and on trader beliefs. Traders often use multiple criteria in making trading decisions”. Since this used economic judgement and not systematic rules this is a discretionary strategy.
