The award-winning New York Times bestseller about the American women who secretly served as codebreakers during World War II--a "prodigiously researched and engrossing" (New York Times) book that "shines a light on a hidden chapter of American history" (Denver Post).

While their brothers and boyfriends took up arms, these women moved to Washington and learned the meticulous work of code-breaking. Their efforts shortened the war, saved countless lives, and gave them access to careers previously denied to them. A strict vow of secrecy nearly erased their efforts from history; now, through dazzling research and interviews with surviving code girls, bestselling author Liza Mundy brings to life this riveting and vital story of American courage, service, and scientific accomplishment.

Instead, concentrate on what’s important: how to construct your own bulletproof portfolio by finding the best individual stocks and mutual funds for you. This timely book is your guide to volatile markets. We live in a world saturated with the short-term: Who’s up, who’s down? Which stocks rose yesterday, which fell?

They’re relaxed—calm, cool, and collected—because the secret code provides the foundation for making superior investments, the kind that generate wealth to fund more interesting pursuits, provide for their children’s education, and fund retirement. Superior investors * Are not outsmarters—people who try to beat the system through inside advice and superior brainpower—but partakers. They know that the best way to make money is to share in the profits of successful businesses. * Own a portfolio that looks like the U.S. economy ten years from now. * Know the kind of investments they should be making (e.g., pharmaceuticals, for-profit education, mind-numbingly boring but extraordinarily profitable companies) and those they should not (e.g., corporate bonds). * Understand when to start selling the stocks they’ve bought: almost never . . . only when the fundamental reasons why they bought in the first place change. * Understand how to pick the companies that will make them superior investors. * See that bear markets are for buying.
