Investors in different parts of the US favour different types of stocks

Openfolio, an app that allows people to share investment portfolios, compiled data from its more than 40,000 subscribers and found some surprising regional bias in people’s stock-picking preferences.

The company examined the top 2,000 stocks that users owned and then separated them by industry, looking to see who owned what companies based on where they lived.

From there, Openfolio calculated the relative probability that investors in a region were likely to be invested in a particular industry.

Looking at the maps below, you can see that people exposed to a lot of “home bias.” In other words, they love investing within their own backyards.

West Coast investors are 10% more likely than average to invest in the tech industry. The region is home to tech giants Facebook, Google and Apple.

Investors living near the banking centres on the east coast are 23% more likely to own financial stocks than those in the Midwest and 9% more than the average investor.

The South, home to large amounts of the country's oil reserves, favours energy stocks such as Exxon and Chevron at over 20% more than in the Northeast and 14% more than average.

General Electric, Caterpillar and other industrial heavy-lifters are found in Midwesterners' portfolios 11% more than average and 20% more than those living on the West Coast

The one thing all investors can agree on is healthcare stocks with only a -/+3% variance across all four regions.

Here are the full numbers from Openfolio, also showing the top stock picks in each of the industries.
