Key takeaways:

• Eagers, Inghams, and Origin make the winners list, while Domino and Qantas headline the week underperformers

With more earnings reports behind us, the ASX is staring at its third weekly loss in a row, as investors weigh up an expected economic slowdown over the coming months.

Which shares excelled?

On the back of a record profit, Eagers Automotive (ASX: APE) is among the top mid-to-large-cap ASX stocks this week. The nation largest automotive sales group recorded $405.2 million in underlying operating profit before tax, with strong demand for new and used cars driving the result. The company investment in technology and reducing its cost base also helped. Shareholders have been rewarded with a final dividend of 49 cents per share.Poultry producer Inghams (ASX: ING) is in the spotlight this week, days after the company announced its earnings. And it is those earnings that have provided encouragement to some onlookers, specifically, major brokers. The stock received an upgrade from Morgans and Macquarie, with the former upgrading the stock to an add' rating, and the latter slapping the share with an outperform' rating on positive signs from the half-year figures.Outside of earnings season, Origin Energy (ASX: ORG) made the news. It appears that the proposed takeover for the major gas player is back on track once again. After its suitors revised their bid lower, albeit by just 10 cents per share, Origin Board has decided to back the proposal. Shares in the company surged in response, with the $8.90 per share offer deemed fair in light of changing government policy.Arafura Rare Earths (ASX: ARU) is also charging higher this week, even though the company hasn't been the subject of any price-sensitive news. It appears as though this jump has been driven by some broad-based interest in battery metals stocks, including Pilbara Minerals (ASX: PLS) and Lynas Rare Earths (ASX: LYC). Following its gains this week, ARU shares are up more than 50% year-to-date.There is also a positive story brewing over at Johns Lyng Group (ASX: JLG). The company, which specialises in integrated building services, published its first-half results for FY23. Investors cheered the update, with the stock up nearly 16% at one point. In the absence of large-scale activity by the company in the commercial construction sector, news of upgrades to both revenue and earnings were the catalyst for the positive trading session, with management citing the benefits of a record volume of business as usual and catastrophe work.The winners list also features Perenti (ASX: PRN), Ooh!Media (ASX: OML), and Weebit Nano (ASX: WBT).

Which shares dragged on the market?

A company that has faced a series of setbacks over the last year or so, namely related to inflation, shares in Domino Pizza Enterprises (ASX: DMP) tumbled this week. The company net profit fell short of expectations, down 21% to $71.7 million. 

Although headline sales increased by 1.2% across the Group, new-store sales largely masked organic growth, whereas online sales fell 4.5%. Operations across the ANZ region fared relatively well - EBIT even increased 5.2% -  but the extreme inflationary environment in Europe proved a major headwind for that segment.

With its interim profits down nearly 40%, there was no escaping a brutal sell-off for Platinum Asset Management (ASX: PTM). Like a number of other fund managers that struggled last year, the company average funds under management were down about 21% year-over-year for the half, which translated into a comparable decline in revenue to $102.3 million. Net profit came in at $37.6 million, versus $60 million a year prior.Engineering firm Monadelphous (ASX: MND) reported a 10.5% decline in revenue for the December half, with net profit after tax sliding 3.1% to $29.1 million. Those figures, and a flat dividend, were enough to unsettle shareholders, with the stock sold off on the back of the result. Despite the company maintenance and industrial services division delivering record revenue, the tail off for its engineering construction segment left a big hole on the company income statement.Although revenue was up 66% for coal exporter Coronado Global Resources (ASX: CRN), translating into higher profits by more than 300%, the stock still finds itself on the list of underperformers this week. A huge jump in coal prices was responsible for the uplift, however, investors focused on one area the company can control - production - where saleable volume fell 7%.Australia national airline Qantas (ASX: QAN) also released its earnings report this week, with the company delivering strong numbers. Bouncing back to profit, Qantas recorded $1.43 billion in underlying net profit, with net debt declining to $2.4 billion. Thanks to cost cutting, elevated airfares, and high yields, operating profit margins reached the impressive level of 16%. 

CEO Alan Joyce also made clear the airline has put some of the company operational gremlins behind it. However, shareholders honed in on one key remark. The company suggested that it will bring more capacity online, with airfares forecast to moderate from current levels in the second-half. A $500 million buyback was not enough to soothe the concerns of some sellers.
