The Art of Short Selling

3 ideas

1. Read filings against management's public story

   The most productive short-selling research compares what a company says in press releases, conference calls, and promotional interviews with what it discloses in its SEC filings and footnotes. Management controls the narrative but faces legal liability for the filings, so bad news is often disclosed quietly in the filings, including related-party deals, changed accounting policies, and contingent liabilities. The gap between the two sources is itself the signal.

2. Balance sheet divergence as earnings warning

   Reported earnings can be manipulated more easily than the balance sheet and cash flow statement, so an analyst should check whether the other statements corroborate the income statement. Accounts receivable or inventory growing faster than sales, operating cash flow persistently trailing net income, and rising capitalized costs or deferred charges all suggest revenue is being pulled forward or expenses pushed out. Frequent accounting changes, auditor switches, and CFO turnover strengthen the suspicion.

3. Being right early can still ruin a short seller

   A short position has unlimited theoretical loss, and borrowed shares can be recalled. Promoters, momentum buyers, and short squeezes can keep an overvalued or fraudulent stock rising far longer than fundamentals justify. Because of this, a short seller needs position sizing that survives adverse moves, and ideally a foreseeable catalyst such as a debt maturity, an audit, or a filing deadline that forces the truth into the price.
