Flickr/ Link576We recently learned a bit of history about hedge fund billionaire Ray Dalio, the founder of the world's largest hedge fund, Bridgewater Associates. It turns out he helped McDonald's launch Chicken McNuggets. In the early years of Bridgewater, which today manages $160 billion in assets, Dalio did some consulting work. At that time, Dalio helped his client, McDonalds, come out with its low-priced Chicken McNuggets. McDonalds was worried about the price of chicken rising, which would either squeeze margins or force the fast-food giant into raising prices.
