JUSTIFIEDCONFIDENCE5/5Rapport fell 12.9% on the day and another 12.33% in the last five minutes after announcing a $200 million common-stock offering and $150 million convertible-notes offering.

RAPP opened at $25.11, briefly matching its session low, then climbed through the day to reach a high of $28.31 before ending regular trading at $27.53, up 8.7% from the previous close. After the close, TapeRank recorded the stock at $21.50, down 15.1% on the day, and read the reversal as justified by Rapport’s announcement of a $200 million common-stock offering and a $150 million convertible-notes offering, which introduced substantial dilution and conversion overhang. There were no halts, and no filings or news had appeared in the 24 hours before the earlier recording.
