Dow Jones says it can measure economic sentiment by reading the press.
By Nancy Miller of The Big Money
Just as a technological revolution is blowing up newsrooms across the country, Dow Jones has come up with an algorithm
to prove that yesterday’s newspapers are useful for more than just fish wrap. According to the publishing giant, you can plumb the language and tone of newspapers to finger turning points in the economy.
The news, it seems, is a moderately reliable economic compass. And today, Dow is quantifying that assertion with the release of its newly minted Economic Sentiment Indicator, a monthly assessment of the “tone” of content in 15 metropolitan dailies. The ESI, informally known as the Optimism Index, is a simple barometer based on a scale of zero to 100—the higher the number, the more upbeat the news and, by extension, the stronger the economy. Dow Jones back-tested the indicator to 1990 and found that it could signal critical turning points in the economy, sometimes a bit earlier than other economic measures.
