Bayard Capital
Andreas Thommen launched Bayard Capital AG in Zurich in 2004 as a specialized investment manager running a single strategy: a concentrated portfolio of short equity positions in European companies the firm believes are overvalued or fundamentally flawed. The firm is not a family office but an independent asset manager structured around a single flagship fund, the Bayard Capital Fund, which publicly discloses its top holdings to investors. Thommen, a Swiss national, built the firm around forensic financial analysis, targeting companies where he alleges accounting irregularities, unsustainable business models, or corporate governance failures that the market has not yet priced in. The firm's investment strategy is entirely focused on fundamental short-selling, with the fund typically holding only 5 to 15 positions at any given time. Bayard does not operate as a long-short equity hedge fund; its mandate is unhedged short exposure, meaning it generates returns when target companies decline in value. The fund takes positions predominantly in mid- and large-cap European equities, with occasional exposure to North American names. High-profile past targets have included the German payments company Wirecard AG — a position Thommen initiated well before the company's 2020 collapse (per the firm's public investor letters, 2008-2020) — as well as the Swiss-listed weather services company Meteoblue Holding AG. The fund operates with an indefinite holding period and is prepared to hold positions through years of corporate denial and legal pushback. Bayard Capital maintains a deliberately lean structure consistent with its concentrated mandate. The team operates from a single Zurich office, with Thommen serving as CIO and the primary decision-maker on portfolio construction. The firm does not operate adjacent vehicles, family office structures, or private foundations, and it does not participate in venture capital, private equity, or long-only strategies. In recent years, Thommen has publicly targeted Swiss industrials and European green-energy firms, releasing detailed critical research that functions as both an investment thesis and a catalyst for the position. Bayard's structure differs from most short-selling funds because it openly publishes its top holdings and detailed investment theses, operating with a transparency typically associated with activist investors rather than hedge funds that guard their short books. This public-facing posture — releasing multi-page reports alleging fraud or misrepresentation — makes the firm a regular subject of European financial media and occasional legal disputes with the companies it targets. The single-fund, single-strategy architecture also means the firm's survival depends entirely on a strategy that has structurally asymmetric risk: potential gains are capped at 100%, while losses can theoretically be unlimited.

Frequently asked questions
What strategy does Bayard Capital run, and how is it different from a typical long-short hedge fund?
Bayard Capital runs an unhedged, fundamental short-selling strategy — the fund only takes short positions and does not offset them with long positions. This pure-play mandate targets companies Thommen identifies as overvalued or fraudulent, with the fund typically holding 5 to 15 positions. Unlike typical long-short funds that aim to be market-neutral, Bayard's returns are entirely dependent on the decline of its target companies' share prices.
How does Andreas Thommen source his short targets?
Thommen and his Zurich-based team conduct in-house forensic financial analysis, scrutinizing public filings, accounting practices, and corporate governance structures for evidence of misrepresentation or structural weakness. Once a position is established, the firm often publishes detailed research reports publicly — a tactic designed to draw market attention to its thesis and act as a catalyst for the stock's decline.
What was Bayard Capital's role in the Wirecard case?
Andreas Thommen was among the earliest and most persistent critics of Wirecard AG. Bayard Capital held a short position in Wirecard for more than a decade before the German payments company collapsed in 2020 amid a massive accounting fraud. Thommen publicly detailed his allegations in investor letters and media interviews throughout the period, including during Wirecard's DAX index membership — a period when most short sellers had been forced out by regulatory and market pressure.
Does Bayard Capital manage capital for external investors, or is it a proprietary vehicle?
Bayard Capital manages the Bayard Capital Fund, which accepts external capital and publicly discloses its top holdings. The firm operates as a regulated asset manager in Switzerland and reports to its investors. It is not a single-family office or proprietary vehicle, though Thommen as founder and CIO is the central investment decision-maker.
What legal or regulatory risks does Bayard Capital face given its activist short-selling model?
Bayard's strategy creates inherent legal exposure because the companies it shorts frequently pursue litigation, regulatory complaints, or public campaigns against the firm. The fund's open publication of critical research means Thommen and his team must ensure every factual claim can withstand legal scrutiny under Swiss and European securities law. Several target companies have publicly accused Bayard of market manipulation in response to its short reports.
