Rough finish to the week: Stocks testing another support level

S&P 500 down 22 points to 2067

I highlighted this level of support earlier and now it's being tested. It's a band of support that extends down to the late-October low of 2017.

If you go back to the August stock market swoon, it started with some selling on a Thursday and Friday and a close on the lows to end the week. That episode was a significantly more dramatic with the S&P 500 down about 35 points around this time of day and extending to nearly 60 points in the final hour or so of trading.

I just don't see the market as ultra-skittish at the moment but if those support levels crack, it could begin to cascade.
