Variety Is the Spice of Investing
Above all, diversify. You wouldn’t fill your closet with all one brand, would you? Similarly, accessorize your portfolio with a variety of companies and industries. That will protect you from losing 100% of your money if one company or industry flames out.

You can do this by investing in an index, like the S&P Global Luxury Index, which tracks the luxury industry as a whole. Putting your money in both small and large companies can help, as can investing in foreign markets instead of just in American companies. And, there are plenty of other fields — tech, banking, real estate, energy, to name a few — that can be smart investment choices.

Now, you’ve made it through our crash course in designer investing. Go celebrate with a glass of Moet & Chandon champagne — and, if you're a LVMH stockholder, that bubbly will taste extra-sweet.
