Several new regulations came to spotlight with MiFID II regulative, one of them is the requirement to report before the end of a business day if investors portfolio has dropped for more then 10% when compared against the valuation at the beginning of a quarterly reporting period. Or if further 10% depreciation happened within the same period. Even though last such event happened almost a decade ago, this part of the EU regulation is made so that investors get a better glance on information about their portfolio in case any more massive turn on happens.
