President Donald Trump's new tax plan could cause a tidal wave of internationally held cash to flood back into the US.
The repatriation tax holiday outlined in the plan, for which details were released on Thursday, is designed to incentivize US-based companies that do big business overseas to bring those profits back home.
By Goldman Sachs' calculation, S&P 500 companies hold $920 billion of untaxed overseas cash, and the firm estimates that $250 billion of that would be repatriated. Looking at all US-based companies, Citigroup says there's a whopping $2.5 trillion of capital stashed internationally.
Once a company brings that money back to the US, it has a few options for how to use it. The first is reinvestment into core businesses — this is most likely the avenue policymakers would prefer, as it holds the most direct bearing on economic expansion.
Another option is for a company to repurchase its shares — this would be beneficial to stock prices and, by extension, the market as a whole. Buybacks are a good way to achieve immediate share appreciation and signal to investors that a stock is viewed as undervalued.
And regardless of how the cash is used, a tax break for multinational companies at least partially addresses what a recent World Economic Forum survey identified as the most problematic factor for doing business: tax rates.
So with that established, which companies stand to benefit most? Goldman says it's those holdings the most post-tax cash overseas relative to their market cap — a group heavily concentrated in the tech and healthcare sectors.
Back in late September, after the initial tax plan framework was released, the firm put together a handy list of the stocks that fit the bill. Here are the ones it has identified as the top 13 beneficiaries.
