My oh my; quite the rigid statement suggesting an inability of someone not being capable of a combination of emotional, intellectual or intuitive decision making regarding their portfolio.
Simply observing weekly portfolio/other market data does not impel or compel someone to take any actions; but can be part of a meaningful learning and study habit. Malcolm Gladwell would likely agree, yes?
As to those who would do harm to their portfolio from weekly observation of same or market data; I suggest these same folks are not yet fully developed to understand their nature. This further suggests these same folks would have some difficulties with other aspects of their live's and decision making. Of course, these folks exist; and may be observed by simply driving on the roads among them and observing their driving habits.
Living in Michigan, where I have experienced the weather extremes of a
120 degree heat index to a -45 degree wind chill factor; if I didn't pay attention to at least the weekly weather forecast, I would be ill prepared to have any sort of plan for anything I may want or be able to do.
I have reviewed the daily and forward weather forecast and discovered I am able to properly position my "work portfolio".
Lastly, we reviewed our portfolio and other market data on Saturday, as is the norm; and I am able to report that no harm has taken place within our investment portfolio.
