The stock market isn't always connected to current events. It's more like poker - where a person's bet is based on what they perceive to be true (even if what they have in their own hand isn't good).
Interestingly there are also 2 sides to it - like interest rates -> rates go down, bond prices go up. Stocks go down commodities like gold and silver go up. PS gold and silver seem to be going through the roof!
This is why it is referred to as a house of cards. If you have ever played that game where you just add another card or you and the next player add one at the same time to make things bigger. Each card adds to the next and you just can't stop building. Well, eventually the whole thing goes down under its own weight.
But we have Bible prophecy that states - life will continue even through the worst of it (men marry, women given in marriage, etc Matt 24:38). This tells us that there can't be a total collapse. Also, Revelation shows us that the "False Prophet" (the Anglo-American World Power) is still there all the way to the end - Rev 19:20. Again, showing it is still together and a separate entity that isn't swallowed into nothingness.
Point? Yes, the system is on the edge, but it wont collapse under its own weight. It is just on us to see how and when Jehovah puts an end to it. Meanwhile, the world goes through cycles of awful and then ok, awful and then OK, we can't let those down or up cycles confuse us or get us distracted. Focus on the Kingdom and not the storm.
