Industrials businesses quietly power the physical things we depend on, from cars and homes to e-commerce infrastructure. Still, their generally high capital requirements expose them to the ups and downs of economic cycles, and the market seems to be baking in a prolonged downturn as the industry has shed 20.6% over the past six months. This performance was worse than the S&P 500’s 12.8% fall.

Investors should tread carefully as timing cyclical companies is a challenging task, and any misstep can have you catching a falling knife. Taking that into account, here are three industrials stocks we’re passing on.

Market Cap: $394.3 million

Playing a large role in the Integrated Pipeline (IPL) project in Texas to deliver ~350 million gallons of water per day, Northwest Pipe (NASDAQ:NWPX) is a manufacturer of pipeline systems for water infrastructure.

Why Should You Sell NWPX?
