I believe there is a misunderstanding.
The posts that you are referring to are not part of the The Daily Brief newsletters, rather they are part of a totally different initiative by Zerodha called In The Money, with traders being its primary audience.
And the post under In The Money are opinions/views of Mr. Sandeep Rao, a SEBI registered Reasearch Analyst. So if they appear to be flawed/biased in your opinion, it is probably because they are just views of this person and doesn’t necessarily have to be backed by facts.
So, don’t confuse In The Money with The Daily Brief.
