Patient Capital Management is a Baltimore asset manager founded in 2020 by Samantha McLemore, CFA — Bill Miller's long-time co-manager (working together since 2002, running the flagship Opportunity Equity strategy since 2014). Continuing the Miller-school contrarian tradition, it practices "time arbitrage": exploiting behavioral mispricing to concentrate in controversial growth names (tech, healthcare, Bitcoin-related) at deep discounts to intrinsic value. Its site preserves Bill Miller's complete 1995-2022 market letters, alongside ongoing quarterly letters and webinars.
This article summarizes a webinar by investment firm Patient Capital. The founder argues that the current US stock market bull run, which started in 2009, is still in the “optimism” phase, not the “euphoria” phase that usually marks a top. She advises investors to stay invested rather than trade often. She compares today’s AI boom to the dot-com bubble: semiconductor stocks have risen just as much, but valuations like Nvidia’s are far lower than Cisco’s was in 2000, so the bubble may be smaller. She also explains that value investing means finding gaps between market expectations and a company’s real fundamentals, not just buying low-price stocks. Worth reading to understand how a professional thinks, but note her firm owns many of the stocks she praises.
Samantha McLemore (founder and CIO of Patient Capital, who worked with Bill Miller for over 20 years at Legg Mason and Miller Value Partners) and assistant portfolio manager Christina Siegel Malbon hosted this webinar on July 23, 2026. McLemore opened by introducing the firm's history and value-investing framework—stock prices are driven by fundamentals (the present value of future free cash flow), and value is the disconnect between market-implied expectations and fundamental judgment—before systematically laying out her assessment of the current market. The most consequential judgment in the entire presentation: "We are still in the late stage of one of the strongest, longest secular bull markets in history, which began in March 2009; sentiment is in optimism, not euphoria; the odds favor the bull market continuing; the best strategy is to sit tight rather than act frequently" (Samantha McLemore). Her strongest evidence: the cumulative gain in semiconductors is comparable to the 2000 tech bubble, but valuations and earnings support are completely different.
Samantha McLemore argues that the only long-term effective driver of stock prices is fundamentals—the present value of future free cash flow; the essence of value investing is not a low P/E ratio, but finding the disconnect between the market's implied expectations and fundamental judgment.
Supporting arguments:
Implication: Operationally, it continues to seek points of disconnect between "market pricing vs. fundamentally reasonable levels," positions where expectations are extremely low, and lets winners run. Readers should note: this is a self-positioning narrative from the perspective of an existing holder; the statement early on that "we have done well" carries a marketing element.
McLemore judges that the current market is in an "optimism phase" rather than an "euphoria phase"; the breadth of localized euphoric signs is insufficient to confirm a top; the late stage of a secular bull market often produces the strongest returns and can last for years.
Supporting arguments:
Implication: She admits "no one knows how it will evolve," but judges that the late stage may still have years to run; risk signals include the controversy ratio touching 70%, accelerating IPO/M&A/capital expenditure, and valuations approaching 25.6x. In terms of market structure, retail investors plus quantitative algorithms already account for 60% of trading volume, and single-stock volatility is in a historically extreme range—volatility creates opportunities for contrarian strategies.
McLemore believes that the AI rally centered on semiconductors is comparable in cumulative gain to the 2000 tech bubble, but valuations are far from bubble-like; supply shortages and earnings growth are still supporting the cycle, and the key question is how fundamentals will evolve.
Supporting arguments:
| Metric | 2000 Tech Bubble | This AI Rally |
|---|---|---|
| Starting point | Netscape IPO (August 1995) | ChatGPT launch (November 2022) |
| Semiconductor cumulative gain | 550-600% | 550-600% |
| Core hardware stock valuation | Cisco peak 150x P/E | NVIDIA 21x P/E |
| S&P 500 cumulative gain | ~200% | 94% |
| Technology sector cumulative gain | 564% | 190% |
| Technology sector P/E | Peak 58x | 21.5x |
Implication: The key variable is how earnings/fundamentals evolve; if the current shortage pattern persists, the cycle still has legs. Note: she holds several of these companies (Alphabet, Amazon, Meta, NVIDIA), so her positive reading of AI returns carries a holder's bias; but she also names Tesla/Apple/SpaceX as overheated, so this is not an across-the-board bullish call.
| Name | Stance | Key Data |
|---|---|---|
| NVIDIA | Bullish (held) | 21x forward P/E; only semiconductor holding, lagging YTD |
| Micron | Not stated (market example) | +247% YTD; 6.8x forward P/E; stock around $1,000; earnings up 8.8x vs. stock up 9x |
| SK Hynix | Not stated (market example) | Believed to represent this rally better than NVIDIA; no valuation given |
| Cisco | Not stated (historical comparison) | 150x peak P/E in 2000 |
| Alphabet | Bullish (held) | Cloud +82%, incremental operating margin 54%, incremental profit $6B, $91B capex → after-tax return >20%; first negative FCF in Q2; +120% from Q1 2025 low; 20-plus P/E |
| xAI | Not stated (AI return observation) | Deals with Google/Anthropic imply after-tax return 30%+ |
| SpaceX | Risk warning | "Crazy priced," extreme indicator of euphoria; may acquire Tesla |
| Amazon | Bullish (held) | No specific data given |
| Meta | Bullish (held) | No specific data given |
| Tesla | Risk warning | "Very overvalued" |
| Apple | Risk warning | "Expensive," AI is the first real risk |
1. "We are still in the late stage of one of the strongest, longest secular bull markets in history; the late stage often produces the strongest returns and can last for years; the current phase is optimism, not euphoria, and the odds favor the bull market continuing" — Samantha McLemore (supporting data: 17-year annualized return of 17% vs. the S&P's long-term average of 10%; Citi checklist at only 64% red flags vs. 97% at the 2000 peak; semiconductor gains comparable to 2000 but valuations are vastly different)
2. "A low P/E is not value; it is a marker of low expectations; value is the disconnect between market pricing and fundamentally reasonable levels" — Samantha McLemore
