WATERLOO, Canada — August 6, 2014 — The severe crash of alternative energy stock prices in 2008 was not likely the result of a bursting speculative bubble and more likely due to the high market risk associated with such stocks. These are among the main conclusions in a new paper published by the Centre for International Governance Innovation’s (CIGI) Essays in Financial Governance project.

In What Drove the Mid-2000s' Explosiveness in Alternative Energy Stock Prices? Evidence from US, European and Global Indices, Martin T. Bohl, Philipp Kaufmann and Pierre L. Siklos write that while US alternative energy stock prices did not exhibit any signs of explosiveness in the mid-2000s, there is “strong evidence of such behaviour for European and international indices.”

But the authors note that the stocks’ idiosyncratic components did not collapse simultaneously with their underlying price indices during the 2008 stock market crash.

They write: “Instead, they continued to increase until May 2009, when the global stock markets had already begun their recovery from the preceding bear market. This finding is suggestive of a substantial reassessment of alternative energy stock prices against the background of intensified sector competition and shrinking profit margins and does not provide conclusive evidence of a speculative bubble.”
