“Ivan Boski was probably the most revered and respected risk arbitrageur on Wall Street. He had accounts with every firm. In fact, he did very little trading with Drexel. He was probably the largest equity buyer of securities of stocks at the time for any firm where he had an account.”

The claim, plainly

Ivan Boesky was one of Wall Street's largest equity buyers and risk arbitrageurs at the time of his investigation, and he did very little trading with Drexel Burnham Lambert.

Assessment

Historical records and SEC filings from the mid-1980s confirm both parts of the claim. First, Ivan Boesky was widely recognized as Wall Street's largest independent risk arbitrageur and one of its largest equity buyers, controlling $1 billion to $3 billion in purchasing capacity by 1986 and frequently dominating daily trading volume in major target stocks. Second, Boesky's high-volume equity execution was handled through major institutional block-trading brokerages (notably Jefferies & Co., Goldman Sachs, Merrill Lynch, and Salomon Brothers) rather than Drexel Burnham Lambert. Drexel's relationship with Boesky centered on capital raising and debt underwriting (such as the $660 million raised for CX Partners), M&A information channels, and a limited set of discrete reciprocal parking arrangements (roughly 16 transactions), rather than routine equity trading.

By 1986, Boesky's investment vehicles (including CX Partners, L.P.) commanded $1 billion to $3 billion in purchasing power, establishing him as Wall Street's premier independent risk arbitrageur.
Court litigation and SEC filings document that Boesky regularly routed high-volume equity block executions through broker-dealers like Jefferies & Co., Goldman Sachs, and Salomon Brothers.
SEC and Department of Justice records confirm that Drexel Burnham Lambert acted primarily as an underwriter and financier for Boesky rather than an equity execution broker, with direct trading between them limited to discrete reciprocal parking transactions.

Sandler: Wall Street establishment targeted Milken after Drexel enabled hostile takeovers

“So Mike was an attractive target because he really wasn't liked by a lot of people in the business round table and in the established firms. He was getting a lot of publicity. He was very successful. And so people complained to the SEC, they complained to Cong…”

Assertion Partly supported

Sandler: Milken pled to violations never previously criminally prosecuted

Sandler: Judge assessed market damage from Michael Milken's violations at zero

“Interesting enough, when the judge assessed the economic damage to the marketplace from everything Michael pled to, included on the three counts that related to Bosque, that the total economic effect of these violations was zero. Not one penny was lost.”

Sandler: Milken received a 10-year sentence via consecutive two-year terms

“And she gave him a ten-year sentence, which number one, negated what we thought was a cap of five years. Because she gave him two years on five counts to Z serve consecutively, not concurrently.”
