Shell Scripting Question: Here is my code, it runs. In my stocks.txt file (also found below) I have 4 stock symbols that I need to output. I get 4 outputs but it is the same one for all 4 boxes as you see when you run the code.

#
# for loop to process stock list
#
clear

while true
do
for stock in `cat stocks.txt`
do
wget -qO- http://finance.yahoo.com/d/quotes.csv?s=$stock&f=nl1c1v >data1

cat data1 | sed s/", "/" "/g >data2
mv data2 data1

change=`cat data1 | awk -F, '{print $3}'`
negative=`echo $change | grep "-" | wc -l`
positive=`echo $change | grep "+" | wc -l`

if [ $negative -eq 1 ]
then
#
# 1 = red, 0 = black
#
tput setab 1;
tput setaf 0;
else
if [ $positive -eq 1 ]
then
#
# 2 = green, 0 = black
#
tput setab 2;
tput setaf 0;
fi
fi
