- Top-down and bottom-up research are two approaches for narrowing the large universe of stocks to focus on for potential trading or investment.
- Top-down starts with analyzing sectors and industries for relative strength compared to the overall market, then identifying leading stocks within those outperforming groups.
- Bottom-up starts with an investor screening for stocks that meet specific criteria they deem attractive, such as valuation metrics or technical patterns.
- Both approaches aim to efficiently filter the thousands of stocks down to a more manageable watchlist for further analysis of individual opportunities.
