Dell Technologies' stock ($DELL) has experienced a significant drop, falling as much as 15.8% in premarket trading on Friday. This decline follows the company's earnings report, which revealed that despite tripling over the last year due to rising demand for AI servers, Dell's earnings and revenue did not meet market expectations. The heavy investments in AI servers are expected to dent the company's gross margin, contributing to the stock's poor performance. Dell's shares have fallen the most in four years as the anticipated profits from AI server sales failed to impress investors. The shares tumbled about 14% as the PC and server maker expects sizeable AI investments to dent its quarterly profit.
