For investors who have been jockeying for the right way to play the U.S.-China trade deal, here's your game plan if the light at the end of the tunnel gets here.

A resolution on trade between the world's two biggest economies could be a big catalyst for a relief rally in the stock market. BlackRock Chairman and CEO Larry Fink said Wednesday on CNBC's "Squawk Box" that there would be "a surge in investment sentiment" if both sides call off tariffs on each other's goods.

Washington and Beijing reached a 90-day truce last month to halt any new levies as they seek to work up a long-term deal through negotiations. There has been mixed feedback on the trade talks — Sen. Chuck Grassley, R-Iowa, said recently that U.S. Trade Representative Robert Lighthizer saw no progress on key issues, while President Donald Trump tweeted about "big progress" with China. In the latest development, China's vice premier, Liu He, has accepted an invitation to Washington this month for trade talks.
