The leg amputation depicted above was supposedly done in under 30 seconds. Dr Liston not only managed to kill the patient (Sepsis), but one of his assistants (Sepsis) – and also one of the audience (shock). A 300% mortality rate! Slack Investor hopes for a better outcome after some recent portfolio surgery.
SaaS-pocalypse
The ‘SaaS-pocalypse’, a trending term to describe the recent and dramatic sell-off in global Software-as-a-Service (SaaS) shares, is based on the idea that AI becomes so advanced that software becomes redundant. – The Guardian
Slack Investor went into a bit of detail last post on the sell off in tech and healthcare stocks due to the release of AI tools such as Claude. This wasn’t just some tale in a distant land, the ‘SaaS-pocalypse’ was having a very direct affect on the Slack Portfolio.

Is this really a disaster for the Slack Portfolio? Slack Investor prides himself on getting things ‘mostly right’. However, this 2026 Financial Year has been testing – it seems that he has been getting things ‘mostly wrong’! However, Slack Investor knows that only long-term results count.
It is certainly a setback, as Slack Investor has attached himself to 5 of these ‘Biggest Fall’ ASX companies set out above. Some remedial action is required.
Slack Investor has been in this game long enough to not panic. He has however given the Slack Portfolio a ‘very hard look’ and has been gradually building up his cash position by selling companies that have not a convincing story to tell in these frothy times – particularly those with an extended PE Ratio. Future incomes may not be enough to justify their expense (high PE Ratio). He is mindful that the recent sell-off might be overdone in some cases.
But the companies being indiscriminately sold are often those whose actual protection was never in the codebase to begin with. The durable moats live outside the software entirely, in proprietary data rights, regulatory licences, institutional relationships, deep workflow embedding, and sustained frontier research. None of these can be prompt-engineered into existence. – Mark Gardner, MPC Markets –Livewire
Since his last published quarterly portfolio, Slack Investor has reduced his exposure to the US market (Sold NVDA, NDQ, JNDQ) and sold off some of his more speculative holdings (TLX, MP1 and CXL). His cash position is healthy and waiting for some future opportunities. His Stable Income pile plus Slack Portfolio dividends are enough for living expenses and holidays. Slack Investor should never be forced into a sale of his stocks.
Rules of thumb when bad things happen
Slack Investor has general rules of thumb for when stock prices have a fall of 20%. These questions must be asked.
- Has something fundamentally changed with the company? Such as sustained falling earnings, new competitors, etc.
- After running the numbers for predicted PE Ratio, predicted ROE and predicted growth. Would Slack Investor buy this company at the current price?
As well, for SaaS stocks, Slack Investor has another question.
- Does the company produce proprietary software and embedded relationships with its clients that would provide a durable moat?
These three questions were enough for me to hang on to my battered software-based stocks TNE, CAR, REA, and WTC – and hope for a recovery.
February 2026 – End of Month Update
Slack Investor remains IN for Australian index shares, the US Index S&P 500 and the FTSE 100.
Despite the turbulence in the Slack Portfolio, it was a good month for the ASX 200 (+3.7%). The FTSE 100 is in record territory with 6.7% February growth. A well deserved rest for the US markets (S&P 500: -0.9%).
All Index pages and charts have been updated to reflect the monthly changes – (ASX Index, UK Index, US Index).
