There is a word for people like Roubini and that is hypocrite
"We'll admit to being a bit perplexed at Nouriel Roubini's personal investment strategy and how it compares to the advice he gives on the pages of his RGE Monitor. Last we heard, Dr. Doom was 100% long, and invested in index funds. That was apparently true as recently as February, when it was reported in the
Financial Times." - Bussines Insider March 19 2009

I even dubbed this strategy the "Roubini barbell". There is the Taleb barbell which is go keep 80-90% of your wealth in safe assets (say developed market gov bonds, plus some gold) and 10-20% in extremely risky assets, like startups, or tech stocks. The idea is that by mixing high risk with safety you are balanced.
The Roubini barbell works as follows, go long a risky market (say equities) then make a CAREER based on bashing that market. If that market soars, you make a fortune off your investments, but your career will struggle. If the market collapses, you career will skyrocket but your portfolio will struggle. So its a HEDGE, you get rich either way.
A lot of people behave like that, they will talk in opposite ways that they are positioned to HEDGE. To me its completetly unethical to do that
A smaller version of that, but that drives me crazy, is when people talk with authority and conviction but they do not have that same conviction in POSITIONING their portfolio. If someone is utterly convinced BTC is worthless, they need to be short. If they are not doing that in their trading account, they need to TONE DOWN their conviction.
What all these people have in common is the lack of integrity, how they present themselves to the real world is not how they really are. You can probably count in your hands how many financial 'gurus' you will see that have true integrity not to do those things. The more 'macho' a guru sounds, the more likely he is engaging in this misleading sort of behavior
When you listen to people without integrity, dont be surprised if they mislead you.
