August was another month during which the Meta Strategy ETF Portfolios have moved in only one direction: Up.

This adds up to 10 out of the last 12 months showing solid gains — with September, one year ago, posting the last drawdown worth mentioning.

Such strong performance triggers a natural reaction in many investors: “Do I have to worry? Can this continue? Wouldn’t it be better to lock in some gains?”

This instinct can become overwhelmingly strong due to the deeply ingrained “loss aversion” bias: Only realizing a loss feels worse than giving back profits we made on paper.

Such behavioral biases are what make a systematic investment framework so valuable.
