FTSE 100 shares have finished effectively these days, however as ever, there are exceptions. I’ve picked up three corporations which have all fallen round 33% within the final 12 months. Their shares are considerably cheaper because of this, however does that make them bargains?

Can Spirax shares decide up steam?

The primary is Spirax Group (LSE: SPX), a specialist in steam administration methods and peristaltic pumps. Sadly, its shares ran out of steam a number of years in the past.

To my shock, they nonetheless look comparatively costly buying and selling at a price-to-earnings (P/E) ratio of practically 24. That’s effectively above the FTSE 100 common of round 15. This both suggests buyers nonetheless have excessive expectations for future efficiency, or that Spirax must unwind additional to qualify as a real discount purchase. I believe the latter.

It did get pleasure from a barnstorming begin to 2025, with its shares surging 20% in January. This was powered by hopes {that a} Chinese language financial restoration might enhance demand for its industrial steam methods. However the rally didn’t final. The share price is sliding once more. Dealer Shore Capital lately flagged structural threats, together with the affect of generative AI and lengthening alternative cycles.

Uncertainty within the international economic system isn’t serving to both. Regardless of growing its dividend for 55 consecutive years, Spirax yields simply 2.22%. Hardly compelling. Proper now, I wouldn’t contemplate shopping for.

Ought to I purchase Rentokil shares?

Pest management specialist Rentokil Preliminary (LSE: RTO) grabbed my consideration throughout final 12 months’s short-lived French bedbug panic, as I questioned if it would profit. I’m glad I didn’t scratch the itch to purchase it although, as a result of its shares proceed to stink out the FTSE 100.

They’re down 16% prior to now month alone, after a poor set of outcomes printed on Thursday (6 March). They included an 8.1% drop in full-year adjusted pre-tax revenue to £703m. Income rose simply 1.1% to £5.4bn.

North American operations have been speculated to be an enormous development driver however have underperformed in follow. With the US economic system nonetheless bumpy, a turnaround might take time.

Rentokil is cheaper than Spirax, with a P/E of 16, however after final 12 months’s slim squeak I gained’t let this infest my portfolio now both. The dividend yield is a modest 2.66%.

Croda shares are affected by lengthy Covid

Speciality chemical compounds firm Croda Worldwide (LSE: CRDA) is the third of my 33% fallers. Full-year outcomes, printed on 25 February, upset, with adjusted pre-tax revenue down 11.6% to £273m. Working margins slipped from 18.9% to 17.2%, prompting the board to launch a £25m cost-cutting plan.

Croda’s shares spiked above 10,000p throughout the pandemic, as panicked clients stockpiled chemical compounds, pulling ahead demand. However right now, they stand at 3,242p, with buyer demand nonetheless “subdued”. Regardless of the droop, Croda nonetheless isn’t in deep-value territory, buying and selling at a P/E of 23.

That is one other dividend stalwart, having hiked payouts for 27 consecutive years. Immediately, it yields 3.4%. It nonetheless doesn’t tempt me.

All three might effectively get well when the broader economic system picks up, however they don’t look primed for a fast rebound right now. I can see higher worth elsewhere on the FTSE 100 proper now.
