I write the Investing For A Living blog. I have been living off my investments as my main source of income since 2006. I focus on developing and managing quant portfolios (TAA based and Individual stock based) targeting high risk adjusted returns which is particularly important for investors in the withdrawal phased of their lives. See my blog for plenty of free info on these topics.
Quant. I run TAA style and individual stock quant models. “Models AND Humans”
