CommSec's 5 most-traded ASX shares last week
Zip Co Ltd (ASX: ZIP) shares dominated investor attention last week after they crashed following the company's half-year FY26 results announcement.
At the close of the ASX on Thursday afternoon, Zip shares had dropped 33.87% to $1.865 a piece. The share price has continued tumbling this week too. At the time of writing the shares have fallen 41.13% since its results announcement less than one week ago.
The price crash ignited investor interest though. Zip shares were the most traded among Commsec clients last week, and by a significant margin too. The data shows 76% of activity was from buyers who were, mostly likely, taking advantage of the low trading price.
CSL Ltd (ASX: CSL) were also among the favorite ASX shares last week. The stock was the second-most traded among Commsec clients, with 66% from buying activity.
The biotech stock had a subdued week last week after it crashed 15% following its half-year results and shock CEO exit earlier this month. At the time of writing the shares are down 13.88% for the year-to-date.
BHP Group Ltd (ASX: BHP) shares were the third most-traded among Commsec investors, although most of the activity (55%) was investors selling up their stake in the mining giant.
The miner's share price jumped nearly 6% throughout the course of last week. The gains have continued through to this morning too. BHP shares are now up 20.43% for the year-to-date. This implies the selling activity is likely investors taking strong recent gains off the table.
WiseTech Global Ltd (ASX: WTC) shares were the third most traded last week. Most activity (68%) was from buyers after the shares dropped another 2% throughout the week, even despite a broader tech sector uplift. WiseTech shares are now down 35.62% at the time of writing.
Commonwealth Bank of Australia (ASX: CBA) shares were the fifth most-traded, but most of the activity (76%) was investors selling up their stock. This is most likely investors taking profits after the shares jumped 10% following the bank's surprisingly strong half-year results announcement earlier this month.
What other ASX shares were investors interested in?
There was also a flurry of interest in buying Electro Optic Systems Holdings Ltd (ASX: EOS), Droneshield Ltd (ASX:DRO), Appen Ltd (ASX: APX) and Telix Pharmaceuticals Ltd (ASX: TLX) shares last week.
There was also a lot of selling activity around Woodside Energy Group Ltd (ASX: WDS) shares throughout the week.
