SPY, the S&P 500 exchange-traded fund, closed the week at $762.60, essentially flat after Friday's risk-on rebound reclaimed a midweek pullback that had briefly knocked the fund to an intraday low of $749.60. The week started and ended within 0.2% of the prior Friday's $764.29 close, but the path between the two was anything but calm.

The week played out in two acts. From Tuesday into Wednesday, investors de-risked cyclicals hard, and SPY fell three sessions in a row from $764.29 to that $749.60 low. Volume spiked to 59.2 million shares on September 16, the heaviest of the month, as financials and industrials absorbed the selling.

By Friday, the tape had flipped. Growth names led the rebound, with the tech-heavy QQQ fund up 1.7% to $716.92 and the technology sector fund XLK adding 2.3% to $188.06 in the session. The VIX, a gauge of expected volatility, dropped 12.8% to 15.44, a clear risk-on close to cap a VIX Jumps 8.4% as Investors Rotate to Defense defensive week.

Sector leadership for the week skewed defensive. Healthcare (XLV) rose 2.1% and staples (XLP) edged up 0.1%, while financials (XLF) fell 2.4%, Fed Hike Exposes Thin Breadth: Financials and Energy Fall, industrials (XLI) dropped 2.0% and utilities (XLU) lost 1.7%. Technology and communication services finished roughly flat on the week but were the engines of Friday's bounce, underscoring a tape that was defending, not breaking down.

For all the volatility, price never gave up its footing. SPY held above the $749 to $754 SPY Holds $754 After the Fed Hike as Breadth Thins support shelf even on its worst day, and the one-month average sits near $764.70, so the fund closed the week back inside the middle of its September trading band. Next week, the question is whether the defensive bid hands back to renewed cyclical leadership and whether Friday's low-volatility close holds.
