Eh, this article is only discussing the US markets.
While the US has been vocal in these geo-political events they haven't declared war or carried out military actions. The US has issued sanctions but received relatively little fallout and backlash from russia in return.
The US is still receiving QE and investors are quite happy.
The markets in Russia have been highly affected by events in Ukraine. On Friday interest rates were raised again from 7.5% to 8%. Inflation is rising and foreign capital is still leaving that country.
Edit:
the sanctions on Russia are not yet going to affect wall st. If any of those sanctions occur (e.g. Investment and banking fields) the markets will react more.
Also, at least the first two levy of sanctions the markets dipped the days before in anticipation of how the US would react. As it hasn't been dramatic the markets aren't holding their breaths right now.
