China still wants to buy large yellow construction equipment, and that’s a good thing for the industrial sector’s largest exchange-traded fund.

The US$11 billion Industrial Select Sector SPDR Fund, ticker XLI, took in over US$565 million on Wednesday, its most since November 2016. The fund is the largest industrial ETF and tracks companies such as Boeing Co., Honeywell International Inc. and Caterpillar Inc.

Shares of Caterpillar (CAT.N) climbed Wednesday after the company said China trade issues are not having a meaningful impact on sales and the pace of equipment replacement is back at normal levels in the country. The industry bellwether had posted its biggest quarterly profit shortfall in a decade in the fourth quarter, attributing part of that decline to China.

Industrials, along with technology, are the most sensitive sectors to the ebb and flow of news about the economy and the trade dispute between the U.S. and China, said Randy Frederick, vice president of trading and derivatives at Charles Schwab & Co. Inc. in Austin, Texas.

“You’re talking about companies like Caterpillar and Deere and Boeing,” Frederick said. “They’re big, giant multinational companies -- they sell a lot of things abroad.”

“As we continue to get positive news from Trump and his administration about progress being made with China, that starts to create optimism that big multinational industrial companies will be able to sell there and be able to sell elsewhere,” he said.

Industrials have been the best performing sector of 2019, gaining 18 per cent this year and 26 per cent since their Christmas Eve low. However, industrial sector ETFs have bled close to US$515 million this month so far, on track for another month of outflows. The sector has not seen positive monthly flows since July.
