2% isn't really a story. VIX is under 30 right now. There's nothing crazy going on in terms of volatility yet. Maybe tomorrow things will be bad but... lets not go chasing after scary stories yet.
I think if VIX spikes to 100 (as it has in the past: when crisis start to happen), then we can talk. But for now, its premature to cast any doom or gloom about this situation.
If you think the Chinese loan company is going to be a problem, feel free to discuss that as the core topic. But looking at the US stock market when the Chinese Bond market is erupting is a bit of a non-sequitur, don't you think?
Given the low value of VIX, the US investors seem rather calm about the event right now. It is news if VIX spikes, as options are bought when investors are scared. But 2% movements and under 30 VIX is rather ordinary, as far as US stock markets go.
