Lam Research (LRCX) shares have rallied a massive 139.25% so far this year, massively outperforming the broader market. This critical AI supplier is cashing in by supplying the deposition, etching, and wafer fabrication equipment needed to manufacture the advanced chips and memory devices powering AI. After a rally like this, investors would be assuming that most of the upside is gone. But Lam’s story is far from finished.
