I feel “talking your own book” is a poor critique.
People are not forced to own or short any stock. They choose to do so. So “talking your own book” is merely explaining that choice.
Now if we want to say they are making false claims or worse knowingly false, that’s another story.
But if what they say regarding a position they are in is true i have zero issue with that in fact i welcome it. .
I don't think it's a poor critique at all. You start with a premise and whether short or long, look for any nook (big or small) you can find to push that premise. Whether things end up true or not is besides the point.
I saw it with GE in a sense even. There was an analyst from JPM who was always against GE before it tanked and he was right in his critiques of the company. His comments would move the stock. But he kept on pushing that negative skew on everything long after things started to get righted and kept his price target artificially low for longer than it should have been. He was in a sense "talking his book," not that he (or anyone he knew) had a short position in the stock (that we know of) but he kept going about things that were being or had been corrected. So in a sense he "was talking his book" was it because he liked the notoriety of being right and wanted to be right again or did or anyone he knew have positions in it...who knows but for sure these kind of things happen both long and short. Later on after he was eventually disregarded, he dropped coverage of GE...shocker.
I don't trust any of them, regardless of whether things turn out right or wrong but with Hindenberg I've seen instances of a lot of nothing in the last 2. They released another report again on that Indian company just a little while back after the first time but not sure that much came of it the 2nd time around as opposed to the first time.
