The shares of Cambridge-headquartered pharma giant AstraZeneca Plc (LON: AZN) tumbled by more than 9 per cent to an eight-month low on Monday after the company announced a $39-billion deal to acquire Boston-based drug maker Alexion Pharmaceuticals Inc (NASDAQ:ALXN).
The stocks got hammered in the early morning trades on Monday with the benchmark FTSE 100 index opening largely flat.

AstraZeneca Plc slips to 8-month low
As per the data available with the London Stock Exchange, the stock of AstraZeneca slipped by as much as 9.19 per cent to an eight-month low of GBX 7,410 from the previous closing price of GBX 8,160 as on 11 December. Today’s steep decline in the share prices has wiped out a considerable gain realised during the recovery period in April from the multi-month bottom levels seen after the Covid-19 pandemic rattled the stock markets globally.
