Lam Research (LRCX) is back in focus after Barometer Capital Management flagged the stock as a key positive contributor in Q2 2026, citing strong exposure to memory equipment tied to AI demand.
Lam Research shares have cooled in recent weeks, with the 30-day share price return down 8.6% and the 90-day move down 18.7%. The stock still carries a strong year to date share price gain of 61.2% and a one year total shareholder return of 156.4%. Momentum has therefore eased near the US$298.22 level as investors digest the raised wafer fabrication equipment outlook, heavier AI related spending, and the step up in dividends and buybacks.

Most Popular Narrative: 29.6% Undervalued
Lam Research is priced at $298.22 while the most followed narrative on the stock points to a fair value of $423.85. This frames the recent pullback very differently.
Lam has greater operating leverage to memory and layer-count growth than any of them, and it owns the specific process steps, high-aspect-ratio etch, through-silicon via formation, copper electrofill, that HBM stacking and 3D NAND scaling physically require. When the constraint is vertical scaling, Lam is the constraint.

If you want to understand why that fair value comes out so far above the share price, focus on three things. The revenue path that narrative sketches through the wafer equipment cycle. The margin structure it assumes stays in place. And the valuation multiple it uses on those earnings that links Lam Research to some of the most highly rated chip equipment stocks.
Result: Fair Value of $423.85 (UNDERVALUED)

Still, Lam Research’s AI memory pitch can weaken if hyperscaler capex slows or if policy changes hit China demand and disrupt that upgrade path.

Another View on Lam Research Valuation
There is a very different read of Lam Research at $298.22 when the focus shifts from that $423.85 narrative fair value to the current P/E. The stock trades around 51.4x earnings, compared with roughly 46.4x for the US semiconductor group and 46.2x for peers, while the fair ratio sits lower again at 44.2x.
That gap means investors are already paying a premium to both the sector and similar stocks, and even to the level our fair ratio suggests the multiple could drift toward over time. The key question is whether the growth and AI exposure justify accepting that valuation risk.
