Retention measures whether users continue using a financial product over time. It is a stronger success signal than clicks alone: sustained use should reflect trust and useful support, not pressure to trade. section 13.1.1 section 13.4.1
Evaluate retention in context:
- Check whether users return the following month after receiving context-aware recommendations. section 13.4.1
- Compare whole feeds, such as generic and context-aware feeds, rather than judging individual articles. section 13.4.1
- Pair retention with measures such as net inflows, portfolio concentration, and panic-driven behavior; clicks alone do not establish financial success. section 13.4.1
A stabilizing recommendation
For users trading aggressively under stress, assess whether stabilizing information is followed by lower churn or fewer forced liquidations. Treat these as outcome checks, not proof that retention alone captures user welfare. section 13.4.1
