I cant understand this. I may be new but this is rediculous. Why cant they have one ticker like DUK for Duke power or PGN for progress energy for christs sake?
Keep in mind that all ETF except the Perth Mint's collect their fees by selling ounces behind each share. For example, the US listed GLD is not 1/10th of an ounce, but 0.097531 ounces (http://www.spdrgoldshares.com/sites/us/value/).
So if you see GLD's price as $1400, it actually equals a spot gold price of $1435.40. Also, because they are deducting each month, the ounce backing is different for each month so you can't just apply 0.097531 to all values on a chart of GLD over a time period (without which technical analysis on a raw GLD price chart is meaningless).
The Perth Mint's ASX listed product (code: PMGOLD) is fixed at 1/100th of an ounce. The only one I think that works that way.
