Welcome to Substack! I discovered your writing via Amrita, who is a supportive fellow finance/wealth writer :-)!

Diversification is most investor professionals still do and recommend. As you said, they have access to data, investment universes, and tools to put together a more "optimized" and diversified portfolio. Hedge funds, as you may know, need to lower overall portfolio volatility but still make consistent performance, so it is hard to be as concentrated as say Buffett's portfolio, which is both concentrated (50% in Apple!) and has very long holding period. It is important for individual investors to research why they put on a stock/position and decide on how much to buy, else investor behaviour, which is sell where there is bloodbath. Now cash is also a wonderful alternative!

Hi Marianne! Thanks for your thoughtful comment. Diversification is indeed important for most investors, but lately I've been exploring this contrarian view that you can concentrate more and still do well. I will elaborate on it on my future posts and I'd love to read your feedback.

Interesting read. Thanks, Alejandro.

Last week we sent out a piece on position size that talked about how investing constantly in your best idea naturally leads to a healthy balance of concentration vs diversification.
