Lam Research Corp. (NASDAQ:LRCX) 

The share price has demonstrated a long-term exponential growth trajectory, increasing from 2.93 US$ in 2005 to 311.35 US$ by 2026. Operating profit per share followed a similar, albeit more volatile, upward path, rising from 0.29 US$ in 2005 to 6.55 US$ in 2026. The Price to Operating Profit (P/OP) ratio serves as the primary indicator of market valuation relative to operational efficiency throughout this period.

Initial Volatility and Valuation Spikes (2005-2013)

The period between 2005 and 2013 was characterized by significant instability in the P/OP ratio. A notable trough in operational performance occurred in 2009, resulting in a negative operating profit per share of -0.22 US$. This volatility culminated in a valuation peak in 2013, where the P/OP ratio surged to 64.12. This spike was primarily driven by a compression in operating profit per share to 0.07 US$ while the share price continued its upward trend to 4.64 US$.

Operational Stabilization (2014-2019)

A period of relative stability in valuation multiples is observed from 2014 to 2019. During these years, the P/OP ratio generally fluctuated within a range of 8.67 to 16.98. This phase reflects a more synchronized growth pattern between the share price and operating profit per share, with profits increasing from 0.42 US$ in 2014 to 1.71 US$ in 2019.

Recent Valuation Expansion (2020-2026)

From 2020 onward, there is a clear shift toward higher valuation multiples. The P/OP ratio moved from 20.40 in 2020 to 47.51 by 2026. While operating profit per share grew substantially to 6.55 US$ by 2026, the share price grew at a significantly faster rate, reaching 311.35 US$. This divergence indicates that market expectations have expanded significantly relative to the actual operating profit growth in the final years of the period.
