b) II, III
c) I, II
d) I, IV
correct answer is d.
A head and shoulders chart, top formation,
is a chart of a stock’s movement that resembles
the outline of a person. As the stock first moves
up, then flattens out forming the first shoulder,
and then moves up again for a brief time, then down
(forming the head), then flattens out to form the
other shoulder the pattern is formed. It is a bearish
chart, indicating the reversal of an uptrend.
