As President Joe Biden's infrastructure plans grow, so too does the potential upside for a handful of materials, construction and machinery stocks, according to Goldman Sachs analysis.

While the brokerage said last week that its infrastructure basket has already made sizable returns since it became clear Democrats would hold majorities in both congressional chambers, Goldman's calculations were based on the White House floating a plan worth $2 trillion.

Now, given reports that the Biden economic team is working on a $3 trillion proposal and a gradual introduction of higher tax rates in the future, Goldman's infrastructure plays could be set for gains in the months ahead.
