Man Behind Noble Group's Collapse Claims 'Bad Companies Have to Die'

The video discusses the rise and fall of Noble, a major commodities trading firm in Asia, whose market cap plummeted from $18 billion to nearly zero due to accounting fraud. Arnold Wagner, the whistleblower, exposed the fraud, aided by journalists Javier Blas and Andy Hoffman. Despite suspicions, Wagner claims he did not short Noble's stock but did short others to cover legal costs. The story is compelling enough to inspire a movie.
