Silicon Motion Technology (SIMO) has drawn fresh attention after its share price crossed above the 20 day moving average. This coincided with recent upward earnings estimate revisions and a Strong Buy rating from third party research.

Over the past month Silicon Motion Technology has seen a 15.2% 1 month share price return, even after a 1 day share price decline of 3.05%. This sits on top of a very strong 172.06% year to date share price return and 212.48% 1 year total shareholder return, which suggests recent momentum has been building as investors react to the earnings revisions and technical signals rather than any major new corporate events.
