Episode notes
Early Tech And Accounting Roots
- Tim Guinness studied engineering then went to MIT and used computing early in his career to analyse company data.
- He credits those experiences with teaching him to read financial reports better than many accountants.
Thirty Equally Weighted Stocks
- Guinness runs concentrated, equally weighted portfolios of about 30 stocks to balance diversification and conviction.
- He enforces a one-in, one-out buy/sell discipline to maintain conviction and avoid slow position drift.
Four-Factor Screening Framework
- Guinness uses four screening factors: value, quality, earnings improvement and momentum to reduce the data glut.
- Momentum helps surface names but deep fundamental work completes the final investment decision.
