Why did open go up today

Opendoor Technologies (OPEN) experienced a significant increase in its stock price today, July 21, 2025, which can be attributed to several factors: 1. **Meme Stock Rally**: OPEN has become a target for retail investors participating in the meme stock frenzy. A popular Reddit post likened Opendoor to Carvana, potentially sparking a wave of retail enthusiasm. The stock's surge, including a 347.21% increase, reflects the influence of meme stock dynamics. 2. **Short Squeeze**: The trading volume for OPEN has been exceptionally high, with 24% of the float sold short as of mid-June. Today's high volume and significant price increase may have triggered a short squeeze, where investors buying to cover their short positions contributed to the stock's rise. In summary, OPEN's stock price increase today is primarily driven by meme stock dynamics and a potential short squeeze.
