Talk about following the money.
Investors looking to beat the need only track the companies that are spending the most money lobbying Washington.
Doing so would have generated profits that easily beat the index—generating alpha, as it's known among investing pros—every year for more than a decade, according to data from Strategas, which uses a proprietary measure it calls the Lobbying Index to track those companies.
"This Index has outperformed the S&P 500 for 15 consecutive years. Not only has the Index outperformed the S&P 500 in the first year, but holding that same Index leads to outperformance in the second and third years as well," the firm said in a research note Wednesday. "In our opinion, this consistent outperformance suggests that the market cannot properly value the return from company lobbying activities."
