Notorious Stock Scams of Recent Years

Notorious Stock Scams of Recent Years

From the Dutch Tulipmania to the South Sea bubble to the Mississippi Company scam, history is rife with instances of investors falling victim to fraud. In more recent times, stock scams have evolved, ranging from accounting fraud that manipulates financial records and conceals losses to pyramid and Ponzi schemes involving fictitious companies.


To prevent future investment disasters, it is important to examine past cases where companies deceived their shareholders. These notable instances shed light on the magnitude of these betrayals. Let's explore some of the most significant cases from a shareholder's standpoint, acknowledging the astonishing nature of these events. Tragically, the shareholders affected were unaware of the deceit and fell victim to manipulation in their investment decisions.

ZZZZ Best: Carpet Cleaning Scam

Barry Minkow, the owner of a carpet cleaning company in the 1980s, deceived auditors and investors by forging more than 20,000 documents and sales receipts. Despite the fraud, he leased and renovated an office building in San Diego with over $4 million. His company, ZZZZ Best, went public in December 1986 and reached a market capitalization exceeding $200 million. Surprisingly, Minkow was just a teenager at the time. However, he was eventually sentenced to 25 years in prison for his crimes.

Centennial Technologies Scam

Emanuel Pinez and his management team at Centennial Technologies engaged in deceptive practices in December 1996. They falsely claimed $2 million in revenue from PC memory cards but were shipping fruit baskets. Employees created fake documents to support their false claims. As a result, Centennial's stock skyrocketed by 451% to $55.50 per share on the NYSE. However, the Securities and Exchange Commission (SEC) discovered that between April 1994 and December 1996, Centennial overstated its earnings by about $40 million. The company reported profits of $12 million while incurring losses of approximately $28 million. The stock then plummeted to less than $3, causing over 20,000 investors to suffer significant losses. Emanuel Pinez was found guilty of five counts of securities fraud, including insider trading and reporting fictitious sales to inflate revenue.

Bre-X Minerals Scam

Bre-X, a Canadian company, was involved in one of the largest stock swindles in history. They claimed to have an Indonesian gold property with over 200 million ounces, supposedly the richest gold mine ever. This caused Bre-X's stock price to soar to a peak of $280, making them instant millionaires. However, on March 19, 1997, the gold mine was revealed to be fraudulent, and the stock crashed to mere pennies. The Quebec public sector pension fund lost $70 million, the Ontario Teachers' Pension Plan Board lost $100 million, and the Ontario Municipal Employees' Retirement Board lost $45 million in the aftermath of the scam.

Enron Accounting Scam

Enron, an energy trading company headquartered in Houston, was at one point the seventh-largest company in the United States by revenue. However, Enron engaged in deceptive accounting practices involving shell companies to conceal significant debts, misleading investors about its financial stability. The company's executives used these shell companies to fabricate revenues by recording one dollar of income multiple times, creating an illusion of impressive earnings. Eventually, the truth came out, causing Enron's stock price to plummet from over $90 to less than 30 cents. This scandal not only led to Enron's downfall but also resulted in the collapse of Arthur Andersen, its auditor, due to the destruction of documents ordered by Enron's chief auditor. The Enron debacle brought the term "cook the books" back into the public consciousness.

WorldCom Accounting Scam

Following the collapse of Enron, another significant accounting scandal shook the equities market. WorldCom, a telecommunications giant, came under scrutiny for engaging in serious "book cooking." The company recorded ordinary operating expenses as long-term investments, considering office supplies as investments in the company's future. This accounting trick involved treating $3.8 billion in normal expenses as investments spread over multiple years, which inflated profits. In reality, WorldCom's business was increasingly unprofitable. The consequences were severe, with tens of thousands of employees losing their jobs, and investors witnessing the stock price plummet from over $60 to less than $1.

Tyco International Scandal

Following the misconduct of WorldCom, Tyco, once considered a safe investment, became embroiled in a scandal in 2002. Led by CEO Dennis Kozlowski, the executives engaged in an elaborate scheme involving unauthorized loans and fraudulent stock sales. Kozlowski, along with CFO Mark Swartz and CLO Mark Belnick, received $170 million in unapproved loans and orchestrated the sale of 7.5 million unapproved Tyco shares, totaling around $430 million. These funds were disguised as executive bonuses and benefits, enabling them to finance lavish lifestyles, including extravagant properties and a $2 million birthday party. When the scandal unraveled in early 2002, Tyco's stock price plummeted by nearly 80% within six weeks. While initially escaping conviction, the executives were eventually found guilty and sentenced to 25 years in prison.

HealthSouth Service Scandal

In the late 1990s, HealthSouth, one of America's largest healthcare service providers, faced a scandal involving CEO Richard Scrushy. Scrushy instructed employees to manipulate earnings reports by inflating revenues and overstating net income. The first sign of trouble emerged when Scrushy sold $75 million worth of HealthSouth shares before announcing an earnings loss. Later, it was revealed that HealthSouth had exaggerated revenues by $2.7 billion. CFO William Owens, cooperating with the FBI, recorded Scrushy discussing the fraud. Consequently, the stock plummeted by 97% in a single day. Although Scrushy was initially acquitted of fraud charges, he was later convicted of bribery. It was discovered that he arranged political contributions of $500,000 to secure a seat on the hospital regulatory board.

Bernard Madoff's Ponzi Scheme

Bernard Madoff, former chair of the Nasdaq and founder of Bernard L. Madoff Investment Securities, was arrested on December 11, 2008, after his two sons turned him in for operating a widespread Ponzi scheme. Madoff, then 70 years old, concealed hedge fund losses by using new investors' money to pay off earlier investors. For 15 years, his fund consistently reported an 11% annual gain. Madoff attributed these consistent returns to a strategy involving proprietary option collars aimed at minimizing volatility. However, this scheme defrauded investors of around $50 billion. He was sentenced to 150 years in prison and passed away in prison on April 14, 2021, at the age of 82.


These scams blindsided investors and resulted in convicted fraudsters serving prison terms, imposing additional costs on investors and taxpayers. While the SEC strives to prevent such incidents, the vast number of public companies in North America makes it challenging to completely avoid future disasters. The moral of the story is to invest with caution and prioritize diversification. Maintaining a well-diversified portfolio helps navigate through such challenges, ensuring that they are mere speed bumps on the path to financial independence.
