If you live on the West Coast, near the technology hubs of Silicon Valley, you are very likely to be overweighted in technology by 9.5 percent or so. Live in the Northeast, and you are overexposed to finance by 9 percent. Investors in the industrial Midwest are likely to have 11.8 percent more industrial companies in their portfolio than the rest of the country. The greatest overexposure is in the South, where energy holdings are 13.7 percent above the average.
Some of this overweight might be due to employee stock option plans. After all, Google’s founders, and most of its employees, live in or around Mountain View, California. Their portfolios are likely to be filled with Google shares and/or options. The same is true for JPMorgan and Goldman Sachs in New York and Boston, Exxon Mobil in Texas, and 3M in Minnesota.
