#1 Steve Ballmer, Microsoft. Without a doubt, Mr. Ballmer is the worst CEO of a large publicly traded American company today. Not only has he singlehandedly steered Microsoft out of some of the fastest growing and most lucrative tech markets (mobile music, handsets and tablets) but in the process he has sacrificed the growth and profits of not only his company but ecosystem companies such as Dell, Hewlett Packard and even Nokia. The reach of his bad leadership has extended far beyond Microsoft when it comes to destroying shareholder value and jobs.
When Mr. Ballmer took over as CEO in 2000 the stock price was $60. Today, the stock trades at the low $30 range. Not all of that loss is Mr. Ballmer's fault as the tech bubble had something to do with the initial loss of value, but it is true that Microsoft completely missed the smartphone explosion and was very late to the party.
Although hes #19 on Forbes list of billionaires, Mr. Ballmer should not be allowed to take such incredible risks with investor money and employee jobs. Best he be retired to enjoy his fortune rather than deprive investors and employees of building theirs.
Bring back Bill Gates!
