Again I ask a most important question: When does the Federal Reserve, like ZNGA, lose all credabilty?
Faith in the dollar can and will turn on a dime. Current strength is by default only, as the problems in Europe are well known and well documented. This will not persist, and things will turn rapidly as they did for Greece, Italy, Spain, Portugal, and Ireland. I think 2013 is the key year. The Mayan calendar is only generally accurate. Its precision is not exact, as those who drew it up were frequent users of peyote.
There are a host of alternatives to the dollar as a storage unit of value. Gold/silver/oil/walnuts (huge rally)/soft commodities in general/agricultural land/guns(check out the chart for Smith&Wesson)/ammunition/ ....and so on.
One can also make a good argument for beaten down real estate. It might be wise to take out a 30 year mortgage right now--it must be fixed rate--and pay it back with increasingly worthless currency. You never pay the loan off early. Just stay current with your all time low interest rate. The problem with most of the above alternatives, the exception being pre-1965 silver coins, is one of liquidity. That is simply the price one must pay to guarantee purchasing power.
How does ZNGA stock behave in this scenario? Well, not good, because the silly inane games have ZERO utility. People will of necessity crawl out of their virtual world, and might even plant a real tomato garden. ZNGA will be erased from the landscape. These thing will come to pass.
