Top-Down, Bottom-Up, and Due Diligence

Top-down, bottom-up, and due-diligence terms used in investment research process design.

Top-Down, Bottom-Up, and Due Diligence terms describe investment styles based on valuation, growth expectations, factor exposure, momentum, contrarian signals, and research process.

Use this branch when a style label changes screening criteria, expected return drivers, benchmark fit, valuation discipline, turnover, capacity, or due-diligence evidence.

What to Check

Check the screening rule, valuation input, growth assumption, factor exposure, benchmark, turnover, capacity, drawdown behavior, and whether the style is implemented consistently.

Common Mistakes

  • Assuming a style label explains performance by itself.
  • Ignoring valuation, factor exposure, turnover, capacity, and benchmark fit.
  • Calling a security cheap or high growth without checking the underlying assumptions.
  • Treating historical style success as a promise of future results.

Bottom-Up Investing

Bottom-up investing starts with company-level fundamentals rather than macroeconomic forecasts, sector calls, or broad market timing.

Top-Down Investing

Top-down investing starts with macro, market, country, or sector views before selecting securities that fit the broader thesis.
