Few would argue that achieving the right balance between change and control is one of management's key tasks. But after several years of declining stock prices, conservative modes of corporate governance appear to be in vogue, belying the belief that management's real responsibility is to create — not preserve — long-term value.To investigate how a focus on maximizing stock-market valuation delivers superior returns over the long term, CFOs from publicly quoted companies based in 19 countries were surveyed. Among the 100 respondents (mainly small-to mid-cap companies along with several major multinationals — all of which managed for value), researchers found that the companies whose stock outperformed the average for their industry sectors in their domestic stock markets (so-called “outperformers”) placed their emphasis on the strategic, the external and change; underperformers focused on the tactical, the internal and control.This survey, which explored each company's understanding of value, the impact of value on strategy, and approaches to operational implementation and to mergers and acquisitions (M&A), revealed three interrelated characteristics of outperformers: a new approach to M&A, a focus on strategy and an enhanced understanding of risk and value.Mergers and acquisitions.
