Hubris

noun
  1. pride or arrogance
  2. (in Greek tragedy) an excess of ambition, pride, etc, ultimately causing the transgressor’s ruin.

Slack Investor possesses all the human frailties – try as he might, even after decades of investing, some of these failings will occasionally surface. Recently flushed with pride with his good performance figures for the past 15 years, he let a few stock plunges go too far – on the mistaken premise that the market will quickly correct itself to reinforce Slack Investor’s view of the world.

A bit of history here … Slack Investor is disciplined in his investing in many ways. However, a trait that he struggles to shake is the sin of hubris. So convinced is Slack Investor of his magnificent stock picking abilities – he sometimes will persuade his inner self that, after a stock price fall, the ‘market’ has got this one wrong! He was so happy while his healthcare stock prices were going up that he brushed aside the unmistakable signs of decline over the past 6 months.

Slack Investor waded into Telix Pharma last year on the strength of its very impressive projected growth figures which led to a very high Slack Factor score. What he didn’t account for is the huge effect of any regulatory problems on potential growth. During reporting season, just the suggestion of problems with the regulators causes great panic.

The Telix share price plunged 18.8% on the day after the company revealed it had run into a snag with the United States Food and Drug Administration (FDA). From Motley Fool, reporting on just one of the TLX shocks that has led to a 30% stock price drop in August 2025.

With hindsight, Slack Investor wishes he had acted more quickly with his stop loss levels, but the falls were so dramatic that only the day traders would be able to get out with some dignity. Slack Investor is not a day trader and looks at his stocks weekly.

What to do about Telix now?

The FDA concerns with TLX were about some future products in the pipeline and the actual 2025 reporting season results were quite goodhopefully, all the bad news is already priced in! It is time to rationally have another look at the stock to decide whether to dump TLX and look for other opportunities. I go to the Market Screener Finance tab for TLX.

Slack Investor first looks at the Income/Projected Income chart to ensure that the income over the past few years and the projected income are showing a rising trend. The next chart down is the Balance sheet. He is looking for debt levels that are well covered by sales. No red flags here.

He then collects a few numbers. PE levels at 170 (December 2024) are frighteningly high … but, if the projected sales growth comes to fruition, the predicted 2027 PE Ratio is a more comforting 21.

A look further down the financial page reveals the predicted profitability (ROE). The forecast ROE for 2027 is a healthy 21.53%. Further down on the page is the predicted Earnings Per Share (EPS). Slack Investor is interested in how these earnings are predicted to grow. For 2025, 2026 and 2027, the forecast EPS growth is 26.04%, 97% and 91.62%

Combining all this data together with other healthcare stocks in my portfolio that had big falls over the past few months helps me determine whether to hold onto these stocks – or not!

WherePE (2027/28) is the forecast P/E Ratio for 2027/28; ROE (2027/28) is the forecast ROE for 2027/2028); EPS Growth is the forecast EPSG for the next three years (EPSG AV). The Slack Factor is a combination of these metrics using the formula defined in previous posts.

Lessons?

Markets can remain irrational longer than you can remain solvent John Maynard Keynes

There is no doubt that Slack Investor should have parked his hubris and let his healthcare stocks go at a much earlier stage in their decline – but for all sorts of human reasons, Slack Investor has found this very hard to do.

However, we are here now … and what should he do? Would he buy these stocks now at the current price? Given these forecast growth figures above … probably! So, for now, I’m being patient and hanging on.

Healthcare stocks often seem to have heroic growth estimates that are easily thwarted for regulatory reasons or the efficacy of competing products. These forecast growth figures can distort simple measures like the Slack Factor.

Mental note to Slack Investor … weather this crisis … and then, reduce exposure to speculative healthcare stocks.
