The Direxion Daily Homebuilders and Supplies Bull 3X Shares ETF (NAIL) attracted just over $500 million in net inflows during 2025, making it one of the top leveraged sector funds after technology. Assets under management stand at $541 million, up from $315 million at the start of the year. This surge underscores investor conviction in a housing recovery, with the underlying Dow Jones U.S. Select Home Builders Index led by D.R. Horton, Lennar and PulteGroup, plus suppliers such as Lowe’s and Sherwin-Williams.

The primary macro driver for NAIL is the direction of 30-year mortgage rates, currently above 6%. Prediction markets assign a 42.5% probability that rates will fall below 6% by the end of January, a decline that would likely spur homebuying and lift homebuilder shares. Conversely, sustained rates above this level could continue to constrain affordability and dampen demand. Investors should monitor Freddie Mac’s weekly Primary Mortgage Market Survey, monthly Consumer Price Index releases and Federal Reserve statements for insights on rate trends.

NAIL’s triple leverage magnifies moves in its largest holdings, which together account for over 18% of the fund’s equity exposure. Key earnings dates include PulteGroup on January 29, NVR on January 30, Toll Brothers on February 23 and Lennar on March 19. A 5% earnings-driven move in any of these names could translate into a 15% swing for NAIL. Metrics to watch include order backlogs, cancellation rates and margin guidance, which will signal whether builders can balance promotional incentives with profitability.
