Consequently, the dearth in available inventory and rising home prices may spur homebuilders to step up construction. So far, housing starts have increased 9.8% to 1.17 million annualized rate, the second-highest level since November 2007.

Even with those encouraging data points, it pays to remember PKB is not a dedicated homebuilders ETF. Over 26% of the ETF’s weight is allocated to the consumer discretionary sector, including giants like Home Depot (NYSE: HD) and Lowe’s (NYSE: LOW).

Nearly 21% of PKB’s lineup is allocated to infrastructure-related materials names, including Martin Marietta Materials (NYSE: MLM) and Vulcan Materials (NYSE: VMC), indicating increased infrastructure spending could be a positive fundamental catalyst for PKB.
