It was another big week for many ASX shares.
Despite the public holiday on Monday shuttering the ASX, numerous companies had defining weeks.
Here are five that really jumped out at me.
ASX shares making big moves lower
Domino's Pizza Enterprises Ltd (ASX: DMP) leapt onto investors' radars on Tuesday. This came following a cost-cutting update from the S&P/ASX 200 Index (ASX: XJO) fast-food pizza retailer.
As part of its efforts to deliver a $55 million increase in annualised underlying performance, the ASX share said it was closing all of its 27 stores in Denmark. Domino's reported it would also shutter 65 to 70 underperforming corporate-owned stores, or some 2% of its global network.
With the company also forecasting slower-than-expected H2 earnings growth, the ASX share was down as much as 12% in intraday trading. The Domino's share price closed down 5.9% on Tuesday.
Another stock that defined the week, with a big move lower on Wednesday, is ASX 200 biotech share CSL Ltd (ASX: CSL). This came after CSL reported a higher-than-expected negative impact of foreign currency moves.
CSL's cut its FY23 profit forecast, citing foreign currency headwinds of US$230 million to US$250 million. The biotech company had previously forecast an impact of US$175 million.
The ASX share closed down 6.9% on Tuesday, having posted intraday losses of 8.6%.
The third stock that made my top five list this week for posting an outsized daily loss is Appen Ltd (ASX: APX).
The AI stock closed down 9.9% on Thursday as approximately 16 million new shares hit the market. That was part of Appen's retail entitlement offer to raise $38 million. This followed an earlier $21 million institutional placement.
The capital raising put the ASX share under pressure, as new shares were issued at an offer price of $1.85 apiece. That was well below the $3.14 per share Appen stock was trading for at Wednesday's close.
Meanwhile, these ASX stocks shot the lights out
Fortunately, there were some very big winners amongst ASX shares as well.
Leading that charge was ASX lithium stock Greentech Metals Ltd (ASX: GRE).
The microcap ASX share closed up a whopping 214.3% on Thursday, having posted intraday gains of 286%.
Investors overheated their buy buttons after the ASX lithium explorer reported on encouraging results at its Ruth Well Project, located in Western Australia.
Results from 22 initial reconnaissance rock chip samples returned grades of lithium mineralisation measuring up to 1.65% Li2O.
Executive director Thomas Reddicliffe was clearly stoked by the results, saying the discovery "positions Greentech as a rapidly emerging critical metals business with an advanced project pipeline".
Rounding off our list, the fifth company that defined the week with a big move higher is ASX 200 energy share AGL Energy Limited (ASX: AGL).
The AGL share price was up more than 15% in intraday trading on Friday, closing the day up 9.7%. The early-day gains saw the stock trading at a new 52-week high.
Investors bid up the ASX share after the company upgraded its FY23 earnings guidance and forecast a bumper year for earnings in FY24.
AGL revised its earnings before interest, tax, depreciation and amortisation (EBITDA) guidance for FY23 to a range of $1.33 billion to $1.38 billion. That was up from the previous guidance range of between $1.25 billion and $1.35 billion.
AGL was even more bullish on its FY24 earnings outlook.
The ASX share also got a big lift from management's forecast that next year's underlying EBITDA will be some 50% higher, expected to be in a range of $1.88 billion to $2.18 billion.
