Transactions valued at $1 billion or more are running above longer-term norms, but deal volume for small-cap and midcap transactions remains below historical levels even before inflation adjustments. BCG's M&A Sentiment Index rose to 83 from 79 at the start of the year, still well below its long-term average of 100.
