Thought I'd post up a bit of an update from those stocks listed in the OP, a couple have seen some good increases based on announcements and so forth.
Start 18/02/10 AUD Gold Close $1237 US Gold Close $1100
Update 01/04/10 AUD Gold Close $1222 US Gold Close $1126
If hypothetically you'd invested $1000 into each stock at the start price, you would currently be $5770 (around 57%) in profit overall. Not bad considering the dismal performance I've seen in most of my holdings and the performance of the Gold price over the same time :)
Please note I have not updated anything except entering updated share price (as of April 1st) and percentage increase/decrease since the starting price (so market caps & other info will not be up to date).
