These 10 companies have reaped the biggest capital gains over the past year – and Biden’s tax plan could send them tumbling, Goldman says

A proposed capital-gains tax hike by President Joe Biden is nothing the stock market can't handle, according to a Friday note from Goldman Sachs' David Kostin.

But some stocks would be more susceptible to losses than others if the proposed tax hike to 39.6% for those making more than $1 million went into effect, according to the note.

"High-momentum 'winners' that had delivered the largest gains to investors ahead of the rate hike have usually lagged," Kostin explained. Over the last few years, stocks within the technology and consumer discretionary sectors have been that largest source of capital gains, meaning those sectors might lag if the tax hike is approved.

These are the ten S&P 500 companies that have delivered substantial capital gains over the past year and would likely lag the broader market if Biden's capital gains tax hike is enacted, according to Goldman Sachs.
