Stocks tend to appreciate when they are added to an index because funds that track that index must now buy the stock. Also, being added to an index results in greater visibility for the stock.

Now what

Envestnet reported a nearly $15 million profit in the first quarter of the year, up from a $7.2 million loss in the first quarter of 2020.

"During the first quarter Envestnet again delivered strong financial results, exceeding our revenue, adjusted EBITDA, and adjusted EPS expectations," CEO Bill Crager said in a statement.

The company looks to be executing on strategies that will enable it to grow fast, putting it in good shape to deliver solid results for the rest of the year.
