M2 supply seasonality - sell in may & go away until October

Using this formula:
(FRED:M2SL+ECONOMICS:EUM2+ECONOMICS:JPM2+ECONOMICS:CNM2+ECONOMICS:INM2+ECONOMICS:GBM2+ECONOMICS:CAM2)/100000000000000

This formula includes US, EU, GB, CAN, JP, In & CN M2 money supply.

You can clearly see M2 money supply seasonality changes, rounding consolidation from June1st & going up starting from October. Every time - for the last 5 years very clearly.
More global liquidity should drive the markets up.
