Index-tracking funds are better for those who don't have time to monitor the market frequently. It's already diversified.
Trading can be done in different horizons. If long term, usually the term being used is 'investing'. Everyone is encouraged to invest, so I think it's just a matter of setting the reminder on when to look at one's portfolio to recalibrate.
For example, if you put in Php10k on a balanced fund account, revisit it after a month (or 6 months, or year, your choice). Do you continue to hold or pull out?
There is no 'one size fits all' strategy. So it's really dependent on the operator what style is best. :)
