Vincent Chen had built his hedge fund from nothing. He had started at twenty-four with two hundred thousand dollars that his father had left him and with the kind of conviction that only young men who have not yet been tested by failure can sustain. He had made his first million by thirty, his first hundred million by forty, and he had reached his fiftieth birthday with a net worth that was estimated, by the publications that tracked such things, at just under two billion dollars. He had done this through a combination of talent and luck and the willingness to take risks that other people were not willing to take—the same combination that produced most fortunes, in the end, regardless of what the people who had accumulated them chose to believe about their own genius.

The strategy that had made Vincent’s fortune was not complicated, in the sense that most successful financial strategies are not complicated. He identified companies that were undervalued by the market, companies whose stock price did not reflect their true earnings potential, and he bought large positions in them. He then used his influence—the analyst reports, the media appearances, the private conversations with other investors that were not illegal but that existed in the gray zone between information and manipulation—to raise awareness of the companies he had bought. The stock prices rose. Vincent sold. He repeated this process dozens of times a year, generating returns that were consistently above the market average.

The strategy required information. Vincent needed to know things before the market knew them—about company earnings, about regulatory decisions, about the private plans of the executives who ran the businesses he invested in. He cultivated sources inside corporations and government agencies. He paid for information that was not always obtained through legitimate channels. He did not break the law, or at least he did not believe he broke the law, but he operated in the space just adjacent to legality where most successful finance was conducted.

The target was a pharmaceutical company named Meridian Therapeutics. Meridian had a drug in development—a treatment for a rare form of leukemia that had shown extraordinary results in clinical trials. The drug was not yet approved. It was not yet on the market. It existed only in the data that Meridian’s executives had compiled from their trials, data that was supposed to be confidential until the company was ready to announce results.

Vincent had learned, through one of his sources, that Meridian was preparing to file for accelerated approval with the FDA. This meant that the drug would likely be approved within months, based on the trial data that the company had already collected. When the approval came, Meridian’s stock would skyrocket—everyone who understood the significance of the data knew this. Vincent intended to be positioned to benefit from that skyrocketing.

He began buying Meridian stock in January. He bought slowly, carefully, through a series of accounts that he controlled and that were designed to be difficult to trace. He did not want to alert the market to his interest. He wanted to own a significant position before anyone realized what he was doing, and he wanted to sell that position after the approval announcement, when the stock price would reflect the drug’s true value.

By March, Vincent owned 8.4 percent of Meridian’s outstanding shares. This was below the threshold that would have required him to disclose his position publicly, but it was enough to generate significant profit if the stock price moved the way he expected it to move. He waited. He watched. He monitored the news for any sign that Meridian was ready to make its announcement.

The leak came from Meridian’s legal department. One of Vincent’s sources told him that the FDA had received Meridian’s application and was preparing to schedule an advisory committee meeting. This was ahead of schedule—Vincent had expected the meeting to be announced in April, but it appeared to be happening in March. He needed to accelerate his timeline.

He made the mistake that would eventually destroy him. He placed a large order for additional Meridian shares, more than he could acquire without moving the market. The order was noticed by the trading algorithms that monitored unusual activity in thinly traded stocks. Within hours, Meridian’s share price had jumped by fifteen percent on volume that was four times the daily average. The jump was reported in the financial news. Analysts asked questions. Meridian’s executives, who had not yet planned to announce anything, realized that something was happening in their stock and launched an internal investigation.

The investigation found evidence of insider trading. The evidence was passed to the Securities and Exchange Commission. The SEC opened a formal inquiry. Vincent learned, through his lawyers, that his trading in Meridian stock was being examined as part of a broader investigation into potential securities fraud.

The inquiry took eighteen months. During those eighteen months, Vincent’s fund lost thirty percent of its value as investors withdrew their money and as the legal costs mounted. The hedge fund that had taken forty years to build was dismantled in the way that all such structures were dismantled: slowly, painfully, with each day bringing new revelations and new expenses and new reasons for the people who had trusted him to stop trusting him.

Vincent was charged with insider trading and fraud. He pleaded not guilty. The trial lasted four months. The evidence was overwhelming—his trading patterns, his communications with his sources, the testimony of the Meridian employees who had leaked information to him. The jury deliberated for three days before finding him guilty on all counts.

His sentence was twelve years. He served seven. When he was released, he was sixty-eight years old, and his fortune was gone, and his name was synonymous with the kind of financial crime that the public used as an example of everything that was wrong with the system.

Vincent wrote a book in the years after his release. The book was about what he had done and why he had done it and what he wanted to say to the people who had been affected by his actions. He did not claim to be innocent. He did not claim that what he had done was anything other than what the courts had determined it to be. He claimed only that he wanted to explain, in his own words, the psychology of someone who had believed, for so long, that the rules that applied to other people did not apply to him.

The book was published by a small press. It sold poorly. The people who might have been most interested in reading it—the people who had lost money in Vincent’s fund, the people who had trusted him with their retirement savings—were not interested in his explanations. They were interested in justice, or in something that resembled justice, and Vincent’s explanations did not provide it.

He lived quietly after that, in a small apartment, on a pension that his lawyers had negotiated as part of a settlement with his former investors. He did not manage money. He did not give advice. He spent his days reading and walking and thinking about the choices he had made and the person he had been when he made them. He was not sorry, exactly. He was something more complicated: a person who understood, at last, the true cost of what he had done, and who wished that he had understood it before the cost had been paid.
