What Are Gurus and Insiders Doing with MU? GuruFocus tracks 23 premium gurus holding Micron, with 14 trimming their positions and 9 adding shares in recent quarters. This mixed but slightly cautious guru activity contrasts with insider behavior, where insiders have been net sellers over the past 12 months, offloading $392.9 million worth of shares while purchasing only $7.8 million. The significant insider selling may reflect concerns about the current valuation or personal portfolio management rather than company fundamentals. This guru and insider ownership flow is a critical differentiator for GuruFocus users, providing a nuanced view beyond traditional data providers like Simply Wall St or Morningstar. What This Means for Investors While Micron Technology's strong GF Score™ and financial fundamentals paint a picture of a healthy and growing semiconductor leader, the GF Value™ analysis and valuation ranks caution that the stock is trading at a substantial premium to its intrinsic worth. The combination of significant insider selling and a majority of gurus trimming positions suggests that market participants are wary of the current price level. Investors should weigh these valuation concerns carefully against the company's operational strengths before considering new positions.
