Intrinsic Value is the price corresponding to a stock's Graham Grade: Defensive, Enterprising or NCAV.
Intrinsic Value(%) is Intrinsic Value ÷ Previous Close, expressed as a percentage.
Defensive Price (Graham №):
Enterprising Price (Serenity №):
BC88.L does not completely clear Graham's qualitative criteria for the Defensive, Enterprising or NCAV investment grades; and therefore no Intrinsic Value or Intrinsic Value(%) could be assigned. However, Graham also specified additional categories for Blue Chips, Utilities & Financials, and Special Situations.
