I
invested
almost
$7,426
for
71
shares
of
PKX
stock
on
July
18.
From
the
day
I
bought
the
shares,
the
price
per
the
share
of
PKX
kept
increasing
until
nearly
$113,
which
is
the
highest
point
on
July
25.
According
to
Zacks
Investment
Research,
POSCO
reported
its
second
quarter
2011
financial
results.
The
revenue
POSCO
got
on
the
second
quarter
has
gradually
increased
22.6%
compared
to
the
year-‐ago
quarter.
Nevertheless,
you
can
see
that
price
per
share
of
PKX
stock
rapidly
went
down
on
July
29
and
went
up
again
in
a
day.
According
to
REUTERS,
Steel
Authority
of
India
Ltd,
which
is
the
largest
domestic
steel
producer,
may
reduce
the
costs
of
its
raw
material.
Conversely,
the
price
per
share
increased
till
the
price
on
the
day
before
it
went
down.
REUTERS
reported
that
POSCO
is
going
to
join
the
lithium
battery
business,
which
is
international
between
South
Korea
and
Bolivia.
So,
this
factor
causes
the
movement
of
stock
price.
Consequently,
the
difference
of
price
between
opening
date
and
closing
date
is
almost
$6,
so
I
was
able
to
earn
$426.71
in
total.
The
profit
is
quite
fine
till
now,
and
I
can
expect
that
POSCO
have
various
potential
and
it
can
bring
profits.
For
these
reasons,
I
will
buy
more
shares
on
this
company
if
I
have
more
money
to
enable
to
invest.
