Stocks have come all the way back to a record, ending one of their fastest and fiercest round trips in history. Here are the front-runners in this epic comeback.

Strong earnings pushed to a record close Tuesday. The index surged nearly 600 points in the span of four months, from a Christmas Eve low of 2,351.10 all the way to 2,933.68 at Tuesday's close.

The comeback is being led by the technology sector, the best performer among S&P 500 sectors with a nearly 37% gain since Christmas Eve. The consumer discretionary and industrial sectors have also scored returns of more than 30% since the late-2018 plunge.
