Not exact matches
This
narrow logical style, says Kinsbourne, admits only «a
few members to any one
category» and attends «to detail in small differences.»
When we added a
few preferences from the many
categories, (height, weight, education level, ethnicity, and career type, etc) our options for potential matches
narrowed significantly, but offered the opportunity to fine - tune matches according to specifications.
Limiting an ad to a
narrow list of interest
categories can also affect performance as there will be
fewer auctions.
For
narrow ETF
categories, or even country - specific products that have relatively small amounts of assets and are thinly traded, ETF liquidity could dry up in severe market conditions, so you may wish to steer clear of ETFs that track thinly traded markets or have very
few underlying securities or small market caps in the respective index.
