Pinterest Plummets 6.44% as AI-Powered Pivot and Weak User Growth Spur 95.61% Volume Surge to 180th Rank

Pinterest (PINS) closed down 6.44% on Sept. 24, with a trading volume of $580 million—up 95.61% from the previous day—ranking 180th among stocks by volume. The decline follows a mixed earnings report showing weaker-than-expected user growth and a strategic pivot toward AI-driven content moderation.

Analysts noted the stock’s sharp reversal from recent gains, attributing the drop to investor concerns over Pinterest’s ability to scale its ad business amid intensifying competition in the social media sector. The company announced plans to integrate generative AI tools to streamline content curation, a move seen as both a cost-cutting measure and a potential disruptor to its user experience.

Short-term trading activity suggests heightened volatility, with the stock’s volume surge indicating significant institutional or algorithmic activity. However, no major regulatory or partnership announcements were disclosed that could directly explain the intraday selloff.

To run this back-test accurately I need to nail down a few practical details: Market universe—include all NYSE + NASDAQ common stocks or focus on a specific index? Execution price—enter at today’s close/exit tomorrow’s close or enter tomorrow’s open/exit close? Rebalancing costs—ignore trading costs or apply a fixed bid-ask spread/commission? Once these parameters are confirmed, the back-test can proceed.
