How traders prepare for Core CPI
- Core CPI has landed at 8:30 New York on most of these releases. Every window on this page is measured from that minute.
- The 4 hours before the print drifted the same way as the move after it on 11 of 22 releases, so the drift in has said little about the move after.
- The typical first-hour range, high to low, has been 0.80%. A stop or a limit order closer than that to the price at the print has usually been reached by the release noise alone.
- Over the longer run, since 20 Jan 2016: on 36 releases hotter than forecast Nasdaq 100 closed the day higher 20 of 36 times; on 47 releases cooler than forecast Nasdaq 100 closed the day higher 28 of 47 times. That is the whole day, other news included.
- The prices are mid quotes from intraday bars, not a broker's fill: spreads widen around a release, so a real order can fill worse than these numbers.
