10 Famous Investment Scams (2024)

This month, the trial of Bernie Madoff’s former secretary Annette Bongiorno is expected to wrap up. Bongiorno is one of five former employees on trial for abetting Madoff’s fraud. Bernie Madoff was sentenced in 2009 to 150 years in prison after his investment firm Bernard L. Madoff Investments Securities fell apart, costing investors an estimated $65 billion in losses – one of the biggest frauds ever seen in America.

Despite working closely with Madoff for 40 years, Bongiorno denies any wrong doing. She believed Madoff’s business was legitimate, and claimed to not understand financial terms like Ponzi scheme, treasury bond and the Standard & Poor’s 500 index, or events like the collapse of Lehman Brothers.Bongiorno allegedly used proceeds from the fraud to finance a luxurious lifestyle, which included a Bentley and plans to purchase a high-end condominium in Boca Raton, Florida, for $6.5 million.

Sadly, victims of Madoff’s Ponzi scheme don’t exist in isolation.

Each year, more than 30 million consumers fall victim to investment frauds. The average loss for an investor stands at $15,000, with individual losses running into millions of dollars. What’s most surprising is that investment fraud victims score higher on financial literacy measures (av. score 58%) than non-victims (av. score 41%).

So why do so many investors get duped? Because the very nature of investment fraud is to not raise any suspicion. High returns and seemingly legitimate financials can go undetected for years. However, as the case of Bernie Madoff highlights, it can all catch up with you in the end. In 2012 alone, the SEC filed 734 enforcement actions for investment fraud.

In light of Ms. Bongiorno’s ongoing trial, Firmex has brought together some of the most famous investment scams of all time. Some you may remember. Others you may wish to forget. We’ve also found some pretty interesting facts about each scandal, which you might not already know.
