Active vs Passive
Portfolio implementation concepts distinguishing manager discretion, index tracking, holding behavior, costs, and benchmark exposure.
Portfolio implementation approaches distinguish investment selection, benchmark tracking, factor exposure, timing, and long-short positioning.
Portfolio implementation turns an investment objective into holdings, position sizes, and trades. Active Management uses investment selection to pursue a mandate, while Index Investing seeks to track a specified benchmark. Trading frequency alone does not identify either approach.
Factor, Smart Beta, and Risk Parity introduces another set of portfolio-construction choices. Evaluate the rule, the resulting exposures, the risk assumptions, and the costs rather than treating a systematic process as a promise of better results.
Tactical Timing and Long-Short Implementation considers changes in market exposure and the combination of long and short positions. Keep the management objective, holding behavior, implementation method, and risk measures separate when comparing strategies. A portfolio can combine several approaches and still lose money.
Choose a subsection first. Deeper term pages live inside each subsection, which keeps large topic hubs readable.

Systematic portfolio approaches that change security weights, target factor exposures, or balance modeled risk contributions.
Timing and long-short strategies change when exposure is held and how it is constructed, with different forecasting, financing, and execution risks.
