***UPDATE June 11th @ 10:31 am EDT: The sell-off in Greece continues...
Although the following Daily chart of the Greek (Athens) General Share Index doesn't yet show today's (Tuesday's) candle, you can see that the current price has fallen below the 200 sma...major support sits at 800.
***UPDATE Tuesday, June 11th:
- See today's Bloomberg article entitled "Greece First Developed Market Cut to Emerging as UAE Raised." The article goes on to say that Greece has become the first developed nation to be cut to emerging-market status by MSCI Inc. after the local stock index plunged 83% since 2007.
- See today's NY Times article -- Greek government is closing down its state-run TV and radio broadcaster to cut costs.
