A friend notified me last week of a new concern (new to me anyway). Perhaps others are in a better position to evaluate his concern. At minimum you should be aware of a big potential problem likely to affect the stock market (and ADVDX).
Bahrain recently had big demonstrations and Saudi Arabia sent troops to intervene in the crisis. The US did nothing. This made the Saudi's realize the US may not come to their rescue even though the US has historically agreed to defend Saudi Arabia. In return for US support the Saudi's have always agreed to price oil in US dollars. Any country that wants to buy Saudi oil must own US dollars. As a result of the Bahrain incident a Saudi prince said it may be time to reevaluate this agreement. If Saudi Arabia decides to drop pricing oil in US dollars it is likely to have a big impact on the US economy and stock market.
If that happens a quick exit from ADVDX (to cash) may be in order.
