After that, leadership can mean enormous growth or catastrophic failure. The companies listed for 2012 are worth studying. Growth in online shopping is hurting same store sales for Best Buy. Its Price of Profitability (as measured by Kapitall) now stands at just 5. Avon (AVP) did not improve shareholder value after turning down a takeover offer this year. The company is now worth $6 billion. In the resource sector, the natural gas price plunge that continued from 2011 turned leveraged assets into liabilities for Chesapeake (CHK). Unsurprisingly, Zynga (ZNGA)’s CEO made the list after its shares lost investors an enormous amount of money. The ill-timed strategic divesture from Facebook (FB) is putting pressure on the company to grow in other markets. Zynga now needs to grow in the mobile space, at a time when profits in this space is itself a challenge – unless the game is a hit. In the Spanish market, Bankia (BNKXF) earned a worst CEO title. The chairman, Rodrigo Rato, is being investigated for fraud. Written by KAPITALL’s Chris Lau .
