I recently prepared a further expert report in a market abuse matter concerning the price sensitivity of equity placing announcements.
The work examined whether announcements relating to proposed share sales or new share issues were likely to have had a significant effect on the relevant share prices. The analysis considered market capitalisation, liquidity, transaction size, discount levels, volatility, peer-company performance, index movements and the wider impact of Covid-era market conditions.
A key theme was the distinction between an immediate “close-to-open” price reaction and a fuller “close-to-close” assessment after the market had time to digest the information. The report also considered whether observed price movements were genuinely unusual, or whether they sat within a wider pattern of volatility already affecting the relevant shares, sectors and indices.
The exercise was a reminder that price sensitivity is not always answered by the headline movement alone. In market abuse and insider dealing cases, context matters: transaction structure, prevailing volatility, sector conditions, liquidity and comparable market behaviour all need to be examined carefully.
