MRNA seasonality — average by calendar month

November carries the highest average at +20.6%, but the median November is +2.3% and 5 of 7 have finished green: +126% in 2020 does most of the lifting. The steadier month is July — positive in 5 of 8 years, median +3.8%. February is the soft spot, down in 5 of 8 with a median of -9.0%. Across its full record it has closed 54% of months higher, swings ±28.9% in an average month and has fallen 95.4% peak to trough.
