On the back of its recent earnings call and bold 2019 predictions, AMD’s stock has had its best day in around three years. But Dr. Lisa Su is positive it’s not setting itself up for a fall by being so ambitious. The announcement that its 2018 full year revenue had grown 23% year-on-year, and represented a second year of double digit revenue growth, has seen AMD’s share price go up by 20% in a single day.

Considering the Nvidia competition has revised its guidance down for its own upcoming earnings call, wiping off half a billion dollars from its Q4 revenue, that’s a quite remarkable performance from the red team. Especially given that Uncle Jen-Hsun saw his company’s share price drop by 15% in a single day. But some industry analysts have suggested that AMD’s 2019 outlook is maybe a little over-ambitious, or simply just “too aggressive,” as Jim Cramer says.

But Dr. Lisa Su, AMD’s popular CEO, has countered that opinion in an interview about the company’s earnings and its 2019 guidance figures. She suggests that while there are definite headwinds to the technology markets still driving hard throughout 2019, the fact the company has a huge range of new products releasing this year will keep pushing AMD forward, swallowing up market share, and continuing momentum.
