Who's Really Moving Your Finger to the Buy Button

You weren't planning to buy anything today. Then your phone tells you which stock is "moving the most right now." A few swipes later, an order screen you never planned to open is sitting in front of you. The question worth asking isn't only "why don't I have more patience." It's also "what was this screen built to make me do."

Does an engaging screen lead to good investing?

In 2024, the UK's Financial Conduct Authority (FCA) published an online experiment involving more than 9,000 consumers using a test trading app. Engagement features like push notifications and prize-draw style incentives could increase trading frequency and risk-taking. The effect appeared larger among participants with lower financial literacy and among some younger users.

This doesn't prove every app is harmful, or that any single feature causes long-term losses for every user. It's a behavior change observed in an experimental setting. Still, it adds one variable to the assumption that "my investing decisions are purely the result of my own analysis": in what order, and alongside what stimuli, were your choices presented to you?

The short path to the order button

1. Attention captured by a surge alert
2. The feeling of not wanting to miss out
3. Checking whether this trade was in the plan

A conceptual diagram for checking your own behavior. It is not a causal model claiming every user reacts the same way.

You don't need to assume collusion to see the incentives

Content providers earn from ads or subscriptions. Financial firms earn from a mix of revenue streams tied to trading activity and account balances. Business structures differ enough that there's no basis for lumping them all into one "cartel." Still, it's worth checking whether the direction that increases page views, session frequency, and trading volume is the same direction that grows your long-term wealth, or a different one.

Platforms have an incentive to increase engagement, and investors get convenient access in return. To judge whether that convenience actually helps, look past trading volume alone and weigh costs, risk, and whether you're actually reaching your goals. There's no need to give up the convenience of modern financial services, but there's also no reason to confuse a convenient order screen with a good decision.

The FCA's 2025 review of 12 trading app operators likewise covered both positive practices and areas needing improvement. A closer look at actual supervision and product design is more useful than a story where regulators stay quiet because they want individual traders to lose money.
