SPY Approaching Long-term Resistance

We can see that SPY is nearing in on a long term ascending support->resistance level. This circled area has the potential to bring some volatility back into the markets in the near future. Combined with Ending/Beginning of year, a red month or 2 in near future would not be at all surprising to see. Fundamentally speaking, not sure what would be the catalyst here, only speaking technicals.
