It’s an old story, from 6 months ago, which has been pretty well corroborated by many other news channels since then. It’s good to be skeptical, but this one is spot-on.
Robert Peston covered it in his book WTF? which is more than a year old.
If the Supermicro story is the only example where Bloomberg has been inaccurate then it still has a far, far better track record than any other press outlet on Earth.
Better than Reuters? I'm not sure about that...
For financial news? Absolutely. There is a reason why Michael Bloomberg is worth $50b.
For financial news, is Bloomberg better than WSJ?
In terms of tradable information, absolutely. Bloomberg is known for being first, not for long narrative stories (of which the WSJ may have an edge?).
