Tobias Carlisle
WATCHAcquirers Funds
Intellectually rigorous quantitative deep-value investor whose books and free screener tools are more valuable than his fund track record; strong philosophical alignment but lacks qualitative depth and AGI awareness.

Investment Philosophy & Portfolio Style
Philosophy
Carlisle's core insight is that 'buying cheap' alone — without quality filters — historically outperforms 'buying cheap-and-quality' (the Greenblatt Magic Formula approach). This was the central thesis of 'Deep Value' and 'The Acquirer's Multiple.' The Acquirer's Multiple is defined as Enterprise Value / Operating Earnings, which he argues is a more robust valuation metric than P/E because it accounts for debt, cash, and is harder to manipulate through accounting tricks. His philosophy draws on mean-reversion: companies that are deeply undervalued and out-of-favor tend to revert toward fair value, often because they attract activist investors, get acquired, or simply recover operationally. He uses quantitative methods to identify these candidates systematically, reducing behavioral biases (anchoring, loss aversion, narrative attachment). He employs forensic accounting screens (Beneish M-score for earnings manipulation, Piotroski F-score for financial health, Altman Z-score for bankruptcy risk) to filter out value traps. His approach is explicitly contrarian — buying what others are selling, and doing so systematically rather than through individual judgment calls.
Portfolio Style
Runs concentrated, quantitative deep-value portfolios. Manages two primary strategies: a Mid Cap Deep Value Fund and a Small/Micro Cap Deep Value Fund. Typically holds approximately 30 positions in the best deep-value opportunities identified by his quantitative screens. While 30 positions is not extremely concentrated by absolute standards, it is concentrated relative to quantitative value strategies (which often hold 100+ positions). Holdings are rebalanced systematically based on the Acquirer's Multiple ranking — stocks enter when they screen as deeply undervalued and exit when they no longer qualify. This creates natural portfolio turnover. The strategy is long-only, no leverage, no shorting, no derivatives — purely systematic equity selection. Holdings tend to be out-of-favor, beaten-down companies across various sectors. The quantitative discipline means he does not override the model based on qualitative judgment, which is both a strength (removes emotion) and a limitation (misses context a human would catch).
Background
Australian-born investor, author, and fund manager. Graduated from the University of Queensland with degrees in Law (2001) and Business Management (1999). Began his career as a corporate advisory lawyer specializing in mergers and acquisitions across multiple countries, then served as general counsel at an Australian Stock Exchange-listed company. Worked as an analyst at an activist hedge fund before founding Acquirers Funds LLC, an SEC-registered investment adviser headquartered in Rolling Hills, California. Author of four influential investing books: 'Quantitative Value' (2012, co-authored with Wesley Gray), 'Deep Value' (2014), 'Concentrated Investing' (2016), and 'The Acquirer's Multiple' (2017, #1 new release in Amazon's Business and Finance category). Also created The Acquirer's Multiple screener (acquirersmultiple.com) as a free quantitative stock-screening tool. Hosts 'The Acquirers Podcast,' interviewing value investors and quantitative researchers. His intellectual evolution tracks from Graham-style net-nets through activist/event-driven investing to systematic quantitative deep value.
Track Record
Carlisle's published backtests in 'The Acquirer's Multiple' and 'Deep Value' show that the acquirer's multiple strategy outperformed the S&P 500 and Greenblatt's Magic Formula over long historical periods (1973-2017 backtesting). However, live fund performance has been more mixed. His Acquirers Fund (ZIG ETF, later restructured) launched in 2019 but was closed after underperforming during the growth-dominated 2019-2021 period when deep value significantly lagged momentum and growth. The DEEP ETF was also launched as a small/micro-cap deep value product. Quantitative deep value as a strategy suffered a historically bad stretch from roughly 2017-2020, with growth and momentum dramatically outperforming. Since 2022, value has staged a comeback, and Carlisle's strategies have fared better. Overall, his real-money track record is shorter and more uneven than his backtested results would suggest — a common issue with quantitative strategies where live implementation faces real-world frictions (liquidity, trading costs, behavioral challenges of investors pulling money during drawdowns). The intellectual contribution (books, research, screener tools) is arguably more valuable than the fund track record itself.
Notable Holdings
Holdings are systematically selected based on the Acquirer's Multiple (EV/Operating Earnings) and rotate regularly. Typical holdings are deeply undervalued, out-of-favor mid-cap and small-cap stocks across diverse sectors. The portfolio does not have permanent 'notable holdings' in the way discretionary managers do — positions enter and exit based on quantitative ranking. Historically, the portfolio has been heavy in sectors like energy, financials, industrials, and materials — sectors that tend to trade at lower valuations. Tech and high-growth stocks are structurally underweight because they rarely screen as deeply cheap on EV/Operating Earnings. This sector tilt is a feature of the methodology, not a deliberate choice.
Transparency & Integrity
Transparency(Score: 9/10)
Very high. Carlisle is one of the most transparent investors in the deep-value space. He has written four detailed books explaining his methodology, publishes a free stock screener (Acquirer's Multiple) that anyone can use, hosts a podcast where he discusses his thinking openly, writes regular blog posts, and shares his quantitative research publicly. His investment process is fully systematic and well-documented — unlike discretionary managers, there is no 'black box.' His forensic accounting filters (Beneish, Piotroski, Altman) are published and replicable. He regularly discusses the limitations and drawdowns of his approach honestly, including periods of underperformance. This level of transparency is unusual in the fund management industry.
Integrity(Score: 8/10)
High. Carlisle is intellectually honest about the challenges of deep-value investing, including periods of significant underperformance. He has been transparent about his funds' difficulties during the growth-dominated market of 2018-2021. He does not oversell his strategy or hide behind cherry-picked timeframes. His books present backtested data with appropriate caveats. He acknowledges the emotional difficulty of holding deeply unpopular stocks and the behavioral challenges this creates for investors. He has been consistent in his philosophy over many years rather than style-drifting to chase performance. His fee structure for the funds is reasonable relative to active management peers. The free screener tool represents genuine value provided to the investing community without direct monetization pressure.
Relevance to Us
Moderate relevance. Carlisle's philosophy aligns well with our emphasis on downside protection, contrarian thinking, and buying cheap. His focus on enterprise value rather than just price, and his use of forensic accounting screens to avoid value traps, are directly applicable to our approach. However, there are meaningful differences: (1) His approach is quantitative/systematic rather than fundamental/qualitative — he buys statistical cheapness, not deeply understood businesses. (2) His 30-position portfolio is less concentrated than our ideal. (3) His holding period is tied to rebalancing cycles rather than multi-year conviction. (4) He has no framework for assessing AGI impact or technological disruption — the quantitative approach is sector-agnostic and backward-looking by nature. His intellectual contributions (books, screener) are more useful to us than his portfolio holdings. The Acquirer's Multiple screener could be a useful tool for initial screening in our floor-price analysis pipeline. His work on 'Deep Value' — the mean-reversion tendency of deeply undervalued stocks — provides empirical support for our floor-price approach.
