Questions & Answers

Mobile trading apps like Robinhood and Wealthsimple Trade have made day trading accessible to anyone with a smartphone and a few extra dollars, eliminating the need for traditional brokerage services.

Q: What are the negative effects of mobile trading apps on investor behavior?

Research shows that mobile trading apps have increased herding behavior, with attention-influenced investors concentrating their trading activity on a small number of attention-grabbing stocks. This leads to poor performance and undiversified stock portfolios.

Q: Do mobile trading apps make day trading easier to profit from?

No, in fact, free trading and the social nature of meme stocks have increased herding behavior, preference for lottery-type stocks, and concentration in attention-grabbing stocks, all of which are detrimental to investor outcomes.

Q: Does the development of app-based herding break efficient markets?

No, market efficiency means that prices reflect all available information, regardless of its source. While app-based herding behavior may impact specific stock prices, it does not break market efficiency overall.
