Subtitled A Long Short Story; foreword by Joel Greenblatt; 2010 edition adds an epilogue.
Einhorn runs Greenlight Capital and documents his six-year short position in Allied Capital, a business development company he argued was overvaluing its illiquid investments and whose lending subsidiary was defrauding a federal loan programme. The book reproduces his analysis in detail, including the valuation methodology Allied used for assets with no market price, the specific loans he examined, and the arithmetic behind his conclusion. He first stated the position publicly at a charity investment conference in 2002, and the book covers what followed.
The more consequential material concerns the response. Allied hired investigators who obtained Einhorn's telephone records through pretexting. The company attacked him publicly and to regulators. The Securities and Exchange Commission investigated Einhorn rather than Allied. Analysts and journalists largely accepted the company's account. The lending subsidiary was eventually found to have defrauded the Small Business Administration and paid a settlement, years after Einhorn had documented it.
His broader argument is that short sellers provide information the market will not otherwise produce, that the structural and regulatory environment treats them as suspects rather than as sources, and that this asymmetry allows misrepresentation to persist.
The book is written by an interested party with a position, which Einhorn states throughout. It is long and the level of financial detail will lose readers without accounting familiarity. Allied disputed the account. Its value is the documented record of what happens to someone who publicly identifies a problem before the institutions do.
Investors interested in analysing illiquid asset valuations and in the practical experience of holding a public short position against an active opponent.
