Navitas Semiconductor Corp (NVTS) is experiencing a significant downturn in pre-market trading on Friday, with shares plummeting 14.67%. This sharp decline follows an extraordinary period of volatility for the stock, which saw a meteoric rise of over 150% during Thursday's regular trading session, followed by a reversal in after-hours trading.

The rollercoaster ride for Navitas' stock price was triggered by a major partnership announcement with industry giant Nvidia (NVDA). The collaboration, unveiled overnight Wednesday, involves Navitas' technology being selected for Nvidia's 800V high-voltage direct current (HVDC) architecture, which will support Nvidia's Kyber rack-scale systems powering their graphics processing units. This news initially sparked intense investor enthusiasm, causing Navitas' shares to more than double in value during Thursday's trading, with gains peaking at an impressive 175%.

However, the market appears to be reassessing the stock's valuation in pre-market trading, leading to the current steep decline. This movement suggests a combination of profit-taking by investors and a potential correction after the previous day's extraordinary gains. Despite the current downward trend, it's important to note that Navitas Semiconductor's stock price remains significantly higher than its pre-announcement levels, indicating that the market still views the Nvidia partnership as a positive development overall. The rapid fluctuations in NVTS stock underscore the high sensitivity of investors to news in the semiconductor sector, particularly when it involves collaborations with industry leaders like Nvidia.
