managing currency risk is extremely difficult imo

indeed as you say who should do it .The company as a whole or us individually as part owners

how does one measure the exposure especially when a lead/lag effect exists between the underlying share price and in the E25 case the price of Mn

how does one manage the so called tail risk. This is the unrealized gain or worse the unrealized loss on the forex hedge. The institution you have traded the currency with will require you to come up with the cash to cover this unrealized loss.

there are also big leads and lags - i.e correlation between share price and the forex hedge may swing very erratically.

i have looked and traded currencies my entire adult life and have come to the conclusion that what works best for myself is simply managing
the currency risk and the equity risk entirely separately.

good luck to all and wish everyone a healthy 2021
