When you have a company like Vystar that reported in its last 10K that they had supply chain issues. Combined with likely hanging their largest revenue source on a manufacture in China, than its a big deal.
You are correct, it would be a bad game plan to have a large position in Vystar or any other company with a China profile or manufacturing ties IMO.
We are already at war with the CCP, it's only going to get real from here.
