Summary
The post is a discussion prompt asking users to share common investing quotes or adages they disagree with.
The author's thesis is that some classic investing wisdom, particularly the anti-diversification quote attributed to Warren Buffett, is flawed. They argue that combining broad market diversification with selective, well-researched conviction picks is a valid and sophisticated strategy.
Quality assessment: This is a philosophical discussion about investment principles. It is noise in terms of providing specific, actionable investment research or analysis.

There are many great quotes, that can guide a mindset. I do like some common wisdom like:
"I think the worst mistake you can make in stocks is to buy or sell based on current headlines"
"If you don't feel comfortable owning something for 10 years, then don't own it for 10 minutes."
"Invest in as much of yourself as you can, you are your own biggest asset by far."
But some other quotes I relate less to.
For instance, I cannot relate much to the following quote:
"Wide diversification is only required when investors do not understand what they are doing."
There are investors, and investors. People who can combine a diversified market exposure with some conviction picks after doing their homework absolutely know what they are doing.
What quotes have you heard or seen, with which you do not agree, or at least can't relate t ?
This is intended to be a light thread, no controversies intended!
