It's a dynamic system.
Rosenberg did finally, after four or so years, get bullish but there are guys like Bob Janjuah who still haven't.
From See It Market:
The last two years of the U.S. stock market’s relentless bid has been, to say the least, at thing of wonder – especially for traders who have been around for more than a couple of decades. From the vantage point of many fundamental/macro analysts, it has repeatedly pushed the upper bounds of value and has yet to take time to even catch its breath. One can argue that the fundamentals looking forward combined with a very low interest rate environment and reduced share float through buybacks have efficiently discounted the risk premium.
That said, it’s hard to reconcile the momentum of this market in the context of 2% – 2.5% economic growth with virtually flat median household income and shallow consumer credit growth. The market has also walked straight through any and all geopolitical risks as “noise”. I cannot remember a market performing so strongly with such a backdrop. To the extent it is or is not supported by fundamentals, it seems appropriate to look to other theories which support the market’s recent momentum.
The basis of The General Theory of Reflexivity
Although Reflexivity Theory is widely attributed to George Soros, it was originally developed as a sociological construct by William Thomas in the 1920s, known as the Thomas theorem, and built upon by sociologist Robert Merton in the late 1940s. The outcome of their work was to define the idea of the “self-fulfilling prophecy” where in predictions often lead component actors to behave in ways that make the “prophecy” become true. As defined in Wikipedia:
“…that once a prediction or prophecy is made, actors may accommodate their behaviours and actions so that a statement that would have been false becomes true or, conversely, a statement that would have been true becomes false – as a consequence of the prediction or prophecy being made. The prophecy has a constitutive impact on the outcome or result, changing the outcome from what would otherwise have happened.”
In the 1950s, philosopher Karl Popper took up the idea in his treaties on fallibility (the uncertainty of knowledge) where the act of studying a scientific phenomenon can affect the outcome. That is where a young George Soros was introduced to the construct while Popper acted as his mentor at the London School of Economics....MORE
