IBM Stock History: 1 Chart You Have to See -- The Motley Fool

Over a century old and recognized the world over, International Business Machines (NYSE:IBM) is the quintessential blue-chip stock. Even its nickname, Big Blue, conjures images of the company's vaunted history among America's business elite. IBM's history contains far more wins than losses; a company couldn't exist for over a century otherwise. However, the current threats facing the company suggest that IBM's stock history is far more complex than it might seem. With the S&P 500 currently trading at a P/E of almost 25, investors should ask why IBM, which 26 sell-side analysts cover, trades at so significant a discount to the market.
