It absolutely does effect anyone's portfolio if invested in anything of widespread accepted value. Oddly enough since this has been going on, crypto has really spiked probably not a coincidence, especially altcoins, a lot. I have read and listened to people that any kind of serious slowdown, or the possibility of a worst case scenario is not at all being priced into markets, which I totally agree with when US markets are hitting all time highs in the middle of this. Millions of people that have access to this story regardless to how limited the information being spread about it are thinking twice about ordering anything from China at the moment. Even if this lasts for say another month or two that is a majorly affected fiscal quarter of the year gone for the Far East's number one economy and the physical producer of many of the planet's goods with any significant resource input. Yes, this will cause a stir and slow down at some point probably sooner than later when the excuse will be "It was a bigger deal than we thought." I will almost guarantee that being the explanation in markets across the world, especially in the US where we are in complete denial of economic reality.
