In afternoon trade, the S&P/ASX 200 Index (ASX: XJO) is on course to end the week with a small decline. At the time of writing, the benchmark index is down slightly to 8,519.3 points.

Four ASX shares that are not letting that hold them back are listed below. Here's why they are charging higher:

Domino's Pizza Enterprises Ltd (ASX: DMP)

The Domino's share price is up almost 22% to $35.99. This follows the release of an upbeat trading update and the first outcomes of a detailed operational and financial review. The latter is aiming to create a simpler and better Domino's. Among the outcomes announced today is a plan to close 172 stores in Japan. These closures are expected to generate $10 million to $12 million annualised EBIT uplift while incurring one-off restructuring costs of $61.8 million. It is also worth noting that as one of the most shorted ASX shares, it is possible that a short squeeze is taking place today amid the good news.

Nick Scali Limited (ASX: NCK)

The Nick Scali share price is up 13% to $18.37. Investors have been buying the furniture retailer's shares following the release of its half year results. While the company posted a 22.8% decline in underlying net profit to $33.2 million, this was ahead of expectations. Also going down well with investors was the announcement of a 30 cents per share fully franked interim dividend.
