A 'V' and a 'W' and Now a 'Square Root' !!

As the "green shoots" of the economic recovery supposedly became visible, the guessing game on the shape of things to come hottened up.

Some said it will be a 'V' - shaped recovery.
Some proffered a 'W' shaped one.
Some others say a double dip recession is in the offing after the initial euphoria.

Now a new theory has come in. Liz Ann Sonders says , its more likely be a 'Square Root shaped one. That sounds quite plausible.
