Is Dow 23,000 a reason to celebrate or a warning signal of a stock market correction, or even worse, a crash? Perhaps it's a little bit of both. The International Monetary Fund recently upgraded its global growth projections, but also issued a caveat, noting that the economic bounce back was breeding “complacency,” that was “spawning financial excesses...While the waters seem calm, vulnerabilities are building under the surface [and] if left unattended, these could derail the global recovery.” Amazingly, these words could have been the exact same warning from ten or thirty years ago.
