Micron Stock Rockets on AI Memory Boom Despite Insider Sales

Micron ( (MU) ) has been popular among investors this week. Here is a recap of the key news on this stock.

Micron Technology (MU) is drawing intense market focus as record AI-driven demand for its high‑bandwidth memory propels the stock while fresh insider selling stirs debate about how far the rally can run. Executive vice president and chief business officer Sumit Sadana unloaded 24,000 shares for about $10.1 million in April, following a $10.75 million sale in February, trimming but not denting a remaining stake valued near $96 million.

These moves come against a backdrop of extraordinary share-price gains, with Micron up roughly 500%–520% over the past year and around 130% in six months, as its HBM4 capacity is already fully sold out through 2026 and demand stretches into 2027. Some analysts argue the memory industry is nearing a cyclical peak and warn that rising capex by Micron, Samsung, and SK Hynix could trigger future oversupply, putting pressure on today’s 70%+ gross margins and elevated valuation.

Others see a lasting AI “super‑cycle” that alters the classic boom‑and‑bust pattern, pointing to multi‑year supply agreements with hyperscalers, long‑term HBM contracts, and expectations of DRAM shortages potentially extending to 2028. Bulls highlight Micron’s massive revenue growth, stronger earnings power, and rising tangible book value, with some forecasts calling for more than $100 billion in cash and EPS far ahead of current consensus by 2027–2028.

Despite short-term volatility and insider sales that have triggered brief pullbacks of 2%–6%, Wall Street sentiment remains firmly positive. MU carries a Strong Buy consensus, with most analysts projecting mid‑ to high‑teens upside over the next 12 months and average price targets clustered around the low‑ to mid‑$500s, suggesting investors still see meaningful room for further gains if AI memory demand continues to outstrip supply.
