Re: 10Ks are uninformative
So far, so normal. WorldCom's leverage was outwardly normal, ie borrow money, build network or other businesses, get your mugshot on Forbes before the DoJ takes one. So detecting shenanigans really needs an understanding of the market before you can try doing comparisons. At the time WorldCom imploded, Sprint was equally fsck'd and for much the same reasons.
Problem was entities that should have been on the side of investors, weren't. So ratings agencies would give telco paper AAA, investors would buy that paper, then find out later it was junk and the rating was just an opinion. And investment banks wanted high ratings so they could sell a few billion of bonds and collect the fees.
And then of course there were the auditors, who should have spotted problems, but preffered to collect fees. Much of the telco stuff was fairly obvious and involved how things like IRUs and access lines were treated. I once got into big argument with sales. Customer wanted to get a decent chunk of capacity between 2 premium countries in exchange for an IRU between 2 cities we weren't connected to, and had no forecasts for. So basically the IRU on offer was essentially worthless, or a liability.
But swaps like that were common. Then contagion spread and other sectors did much the same thing, as Vanity Fair described it. My bank has a cat, your bank has a cat. Mine's worth $10bn, so is yours. So let's swap cats and we'll both have $10bn to spend. And it took the market quite a to figure out the security was just a pair of Icelandic moggies.
And then there was mortgage backed (in)securities, or DotCom2.0 with valuations waaaay out of line with value, or fundamentals. And much the same risks, that sometimes aren't. Like pretending something is new and disruptive when it fundamentally isn't. Or the risk of larger-than-Ebbers sized margin calls influencing CEO behavior. Or journalists baffled by bs. Musk asks twatter if he should flog $10bn shares. MSM goes wild! A few even notice the sale was filed before the poll. Or that there was a $15bn tax bill due.
But such is political. At least regulators have powers to compel. Or ignore given the revolving doors beween regulators and investment banks.
