Investors curious about the next move in the broader market would be wise to pay extra attention to shares of multinational tech giant Apple (AAPL).

"One of the reasons that has been helping sentiment, particularly in industrial stocks and things like that, is the idea that China is going to be reopening," Interactive Brokers chief strategist Steve Sosnick said on Yahoo Finance Live (video above). "If there is another wave of lockdowns in China, that really upends that story. It upends global growth potential. And so, yes, Apple could be the canary in the coal mine."

Apple stock has gained about 2% in the past month, underperforming the S&P's nearly 7% gain.
