Options activity in utility stocks signals potential end to bond sell-off

The U.S. bond market showed signs of stabilization on Thursday, marked by a strong intraday surge in the iShares 20+ Year Treasury Bond ETF (TLT), which recorded its best session in over a month. However, equally significant movements occurred in the options markets, particularly within the utilities sector.

Data from CBOE LiveVol and SpotGamma indicates that trading volume in the State Street Utilities Select Sector SPDR ETF (XLU) spiked to ten times its 30-day average shortly after the market opened. This unusual activity centered on a $1 million position designed to protect against further declines or profit from a potential rally in utility stocks.

The relationship between bonds and utilities has been strained as interest rates climb. Historically, dividend-heavy utility stocks compete with fixed-income instruments for investor capital; as bond yields rise, utilities often suffer. Consequently, XLU has maintained a steep negative correlation of -0.94 with the 10-year Treasury yield over the past 30 days, according to ThinkOrSwim data.

The specific trade structure involved selling 5,000 put options with a strike price of $39 expiring in mid-January for $695,000, while simultaneously purchasing 5,000 call options with a $42 strike for the same expiration date for $400,000. With XLU trading just above $39 at the time of execution, the strategy offers a maximum payout range between $39 and $42.

While analysts note this is not an aggressive bet on a sharp rally, it represents a cumulative shift in options flows throughout the week. Market participants appear to be positioning for the possibility that rate hikes have exhausted themselves and that the utilities sector may have found its floor.
