No One Would Listen: A True Financial Thriller. And while I've enjoyed many books more, it's still intriguing to learn of the extent Markopolis went to alert the SEC of Madoff's Ponzi scheme. For roughly ten years he repeatedly alerted them of his findings, providing enough details to justify his beliefs, but he was ignored.
There are many "must read" (or often in my case, listen) books that those involved in investing should pursue and this is one of them, given the impact Madoff has had and Markopolis' long pursuit. You'll not only gain insights into Madoff but Markopolis, himself! In his own words he is a bit of an eccentric. I think you'll enjoy it.
By the way: The Spaulding Group's May webinar will be dedicated to the topic of Madoff, with a guest presenter! Details to follow.
In the spirit of full disclosure, I want to alert you that I've signed up to be an Amazon Associate, meaning that if you make a purchase from my blog I will be compensated. I don't expect to retire on any money raised, but feel you should at least know of this new relationship. Note also that I would be recommending the book even if I didn't participate in Amazon's program.
