ECB researchers studied, 21 market moving U.S. indicators and third of them shows evidence of inside trading. Researchers studied price movement ahead of data release (known as price drift) and found prerelease price drift accounting for half of the price impact from the release. Researchers have worked on S&P 500 and 10 year treasury notes and it shows millions of Dollar can be made each year from S&P 500 alone.
These infamous sevens are - Conference Board’s consumer confidence index; the National Association of Realtors’ existing and pending home sales; the Bureau of Economic Analysis’ preliminary gross domestic product announcement; the Federal Reserve Board’s industrial production; and the Institute of Supply Management’s manufacturing index.
After the report, regulators and data providers are likely to tighten their grips over the releases but still without sophisticated gadgets and algorithms, retail traders can hardly profit from data trading.
