SunEdison at risk of bankruptcy, unit says; shares plummet 60 percent

- complex accounting structure that includes many sub companies funneling money and debt from one to another, check

- late on filing their financials, in fact today is the last day they have to file to be in good standing with the SEC, check

- huge amount of debt relative to revenue, check

- SEC investigation into their accounting practices, check

- rapid growth in the past that was mostly due to heavily financed acquisitions, check.

- high short interest ratio, check.

Though to be fair to the last point their SI has come down alot in the past couple of months as the stock became too expensive to hold borrow, and now that its at 50 cents/share, its not longer a good short target as the upside/downside is no longer that compelling. People probably have KBIO still fresh in their minds:)

Edit: https://www.reddit.com/r/wallstreetbets/comments/4clo1y/i_to... seems many of them lost

Wonder if that's related to this?

there are probably a couple dozen such energy,mining ,drilling, etc companies that may fall 50% in a week.

A 4 cent investment ($4 per contract) can turn into $1-1.5 ($150) if the timing is right
