eh BirdMan bro, i ain't no sifu lar, still have not millions to swim in (like Uncle Scrooge McDuck )

1. what is the meaning of 25 percentile data to u? what decision can be make based on this data.
Just a simpleton statistical trigger for me to "vulture" a bit more at it.
The "25th percentile NAV" means a point in the historic NAVs, at the 25th percentile (ie. way below the 50th percentile, AKA Median or true average).
I'd "vulture" more if it was below 5th percentile (another trigger)
General idea: Buy more NAV is run-over by train/road kill AND it is something i'm looking for to fill up a position in my Asset Allocation / team of players.

NOTE:
Pls don't buta trigger "just like that" yar, i've filtered the fund/stock based on my own needs first, THEN setup the triggers of 25th & 5th percentile for "vulture-ing" on (extra from my quarterly DCA+VCA).
2. what is the use for "3 years MA - Std Deviation"? I am creating it with "1 year EMA - std deviation" since no enough data.
Another simpleton stats to trigger me that a fund has fallen hard to be "vultured on"
i took 3 years as a historic point in time and its standard deviation coz i wanted a mid-term trigger (as opposed to the above which is since inception)

Note:
Std Deviation = how far left or right of the average (ie. outliers).
Thus, if say something has an Average returns of 10%pa & std deviation of 6%, we can generally say that generally, the returns ranges from 4% (10%-6%) to 16% (10% avg + 6%)

er.. statistical gurus & mathematical geniuses, please correct if i'm in lalaland yar.
