Are there WSB alphas? Academia says yes.

I'm copying the abstract of the paper (Bradley et al. 2021 WP) — don't blame me on that.

We examine the market consequences of due diligence (DD) reports on Reddit’s Wallstreetbets (WSB) platform. We find average ‘buy’ recommendations result in two-day announcement returns of 1.1%. Further, the returns drift upwards by 2% over the subsequent month and nearly 5% over the subsequent quarter. Retail trading increases sharply in the intraday window following publication, and retail investors are more likely to be net buyers following reports that earn larger returns. Thus, in sharp contrast to regulators concerns that WSB investment advice is harming retail traders, our findings suggest that both WSB posters and users are skilled.
