We've come beyond the threshold of absurdity even for Charedi shenanigans. It seems that it has become Assuer to own any stocks, lest they be involved in Chillul Shabbos or other Halacha compromising activities.
But wait! This is not all. The Gedoilim always have a Refuah Kodem L'Makoh. So there are Hechsherim for ETFs and bonds etc.
And so the contest is on! Who can correctly predict the next thing to be Assur. The winner gets to monopolize the Hechsher ensuing from that Issur.
