Shares of Opendoor Technologies Inc (OPEN) surged 15.76% during Friday's trading session, continuing a remarkable rally that has seen the stock more than double in value over the past week. This dramatic rise is largely attributed to a resurgence of meme stock mania, with retail investors on social media platforms driving intense speculation and trading activity.

The online real estate platform has become the latest target of retail traders, reminiscent of the GameStop saga in 2021. Interest in Opendoor on social media platforms has skyrocketed, with some investors drawing comparisons to Carvana's recent turnaround story. The stock's popularity on platforms like Reddit's WallStreetBets forum has increased significantly, fueling the ongoing rally.

Adding to the momentum is a potential short squeeze, as over 25% of Opendoor's float was reportedly sold short by the end of June. The high short interest, combined with increased retail attention, has led to record-breaking trading volumes and options activity. However, analysts caution that the fundamentals of the company remain challenging, with Opendoor facing financial difficulties and a sluggish housing market. As the stock experiences extreme volatility, investors are advised to approach with caution, recognizing the speculative nature of the current rally.
