When there are 4 in a TAG, a fast rule of thumb is that the difference between the 5th and the current TAG, divided by 5 is the change in TAG.
Not mentioning names, but there is a star of a "disappointing movie." THe MovieStock price is still about 70 more than the StarBond;s TAG. The extra 70, divided by 5 is about 14 added to TAG (dROI is a healthy 1.20)
Might be a StarBond pick of the Day.
