What to Check

Check the benchmark, holdings, factor exposure, tracking error, turnover, costs, tax impact, leverage, short exposure, rebalance rule, and whether the implementation matches the stated mandate.

Common Mistakes

  • Assuming passive, active, factor, and smart-beta labels are self-explanatory.
  • Ignoring tracking error, turnover, tax drag, and implementation cost.
  • Using market timing without defining evidence and risk limits.
  • Comparing active results without checking benchmark fit.

Active Management

Active management is a portfolio strategy in which managers select securities, weights, and timing decisions to try to outperform a benchmark.

Closet Indexing

Closet indexing describes an active fund that closely tracks a benchmark while charging active-management fees.

Index Investing

Index investing tracks a market index through funds or portfolios designed to match benchmark exposure with low turnover and cost.

Passive Investing

Passive investing seeks benchmark-like returns by holding broad market exposure instead of frequently selecting individual securities.
