The Mispricing of Complex Derivatives: A Recipe for Disaster

Financial markets have seen an increase in the trading of complex derivatives, including speculative securities that offer high returns but also come with significant risks. Procter & Gamble's purchase of a portfolio of these securities from Bankers' Trust in the early 1990s and the Scottish Life international income and growth bonus bond, which lost two-thirds of its capital, are examples of the potential pitfalls. Zero-preference shares in split-level investment trusts have also come under scrutiny, with Britain's Financial Services Authority demanding compensation for buyers. These complex financial instruments are mispriced, making them appealing to sophisticated investors, but valuing them requires advanced mathematical models and historical data. The people best equipped to assess their value are the sellers, who create products that are difficult for buyers to understand.

Key Takeaways:

  • Procter & Gamble purchased a portfolio of complex derivatives from Bankers' Trust in the early 1990s, which has raised concerns about the mispricing of these securities.
  • The Scottish Life international income and growth bonus bond lost two-thirds of its capital, affecting small investors who received guaranteed income but also took on significant risk.
  • Zero-preference shares in split-level investment trusts have been criticized, and Britain's Financial Services Authority is demanding compensation for buyers.
  • Valuing complex derivatives requires advanced mathematical models and access to long series of historic data, making it difficult for many investors to understand their risks and rewards.
  • The sellers of these complex financial instruments are often the only ones equipped to assess their value, creating a conflict of interest.
  • The problem lies not with regulation but with the lack of trust in the financial market, which can be re-established by businesses demonstrating integrity and reliability.
  • Investors should not buy financial services products they do not understand, a maxim that has served Warren Buffett well enough.
