I'm not bullish on gold because it's a great asset. After all, it doesn't generate cash flow which is why it differs from other assets like real estate (e.g. rent). I'm bullish on gold simply because there is no better alternative. Treasuries, bonds, equities?? I would have none of these except gold and silver ETF's and gold mining stock, among a few other energy plays and only for day trading purposes and very short-terms.
All my other money is tied up in the Norwegian Krone, the Canadian dollar, the Australian dollar, bullion, and commodity based equities in the countries previously noted. I even have cattle on my fathers ranch. Trade King offers the lowest transaction costs on the 'net, as far as I know, and it suits my needs of getting in, taking short-term gains, and getting out fast while I sit at work with hours of nothing to do as an accountant.
Furthermore, gold and silver are the only asset class that also act as a currency and have over a 5000 year track record. Aside from the fundamental aspects of the metals, look at gold for example from a technical aspect. Gold is still trading above it 50 and 200 day moving average. That alone without looking at RSI and other indicators gives me confidence. If you want to make higher gains on speculation, take a look at gold mining stocks. I made a killing on junior gold mining ETF...
I believe my success in analyzing the markets, my approach to investing and trading has been because of the teachings of the Austrian school of economics. I highly encourage people to visit www.mises.org and learn more about it.
