After a rough 2018, Mattel, Inc. ( MAT -0.63% ) is off to a strong start. The company reported results that beat estimates on both the top and bottom lines as strong sales and cost savings of $521 million last year helped it generate its second consecutive quarter of profitability. In many ways, Mattel produced its best quarter since 2009. Investors cheered the results, sending the stock up more than 20% on Friday.
