Apologies to all readers who may have jumped on the CSL train in the past 5 years due to Slack Investor continually ‘bigging up’ this grand old stock. He has always been impressed with companies that spend a good portion of their profits in Research and Development.

Slack Investor has been a holder of this company since the ‘good old days’ (before 2020). But has occasionally topped up when the price dipped below $300. So, he does share some of the recent pain.
The latest price slump was on the back of the FY 2025 results and the announcement that one of CSL’s components, CSL Seqirus, was to be demerged. The markets were not that impressed with the planned restructure and slowing growth momentum.
However, some sectors of the business are doing well. CSL Behring and CSL Vifor reported strong growth.
This CSL horse should have some good riding ahead
The 2025 AGM indicated that management were taking the knife to costs and staff in a restructure of the business that is underpinned by the Seqirus spinoff and $500 million in pre-tax savings.
‘Despite all the headwinds from competition and regulatory price cuts, they’re (CSL) still growing double digit. I think that’s a pretty good business.‘ Daniel Moore – IML, reported in Livewire
When nervous … Slack Investor will always go back to the numbers. Market Screener – Finance Tab for CSL supplies some of the answers. The Income chart looks healthy.

Looking at the projected PE, ROE and growth from Market Screener – future predictions look OK.

Perhaps the big growth days of CSL are in the past due to the more competitive environment in some sectors of the business. However, Slack Investor is a long-term investor in CSL and happy to hold. He would buy more – if CSL wasn’t already 8.1% of portfolio.
September 2025 – End of Month Update
Another wild month. The S&P 500 (+3.5%) and the FTSE 100 (+1.8%) remain in all time high territory. The ASX 200 sputtering and down 1.4% for the month.
Slack Investor remains IN for all markets.
The recent strength of the US market has pushed the closing monthly value to more than 15% above my old stop loss. I adjusted the stop loss upwards to a new ‘higher low’ of 6212 for the S&P 500.
All Index pages and charts have been updated to reflect the monthly changes – (ASX Index, UK Index, US Index).
The quarterly updates showing the current holdings and cash position of the Slack Portfolio have also been completed.
