script doubt

[L.V.Gandhi <lvgandhi@gmail.com>]

I have a scipt as follows.
#!/bin/bash
cd /home/lvgandhi/stock
tf=modbhav
rm -f AngelGoldPrice
for symbol in $(cat AngelGoldHoldings.txt)
do
grep "$symbol,"  $tf >> AngelGoldPrice
done
in the forloop if I put echo $symbol, i get all the lines of file
AngelGoldHoldings.txt. Each line in this file has a word without space
all letters. modbhav dfile exists in /home/lvgandhi/stock. It contains
lines having symbol and other parameters in addition to other lines.
But I get empty file AngelGoldPrice. Where am I going wrong?
