Asset investment philosophy:
I invest in tech value stocks or platform enterprises with substantial network effects, scale economies, and information cascades etc such as Facebook, Apple, Microsoft, Google, Amazon, Nvidia, and Tesla (FAMGANT). All of these platform enterprises reap rewards in the form of both exponential user growth and revenue generation. The long-term fundamental intrinsic value steadily rises over time. One of my favorite stock investment strategies involves buying tech value stocks with competitive moats and first-mover advantages when their share prices fall below the respective book values.
