STMicroelectronics returns to growth, shares lose 20% in a month
On 5 November 2026, two media outlets reported that STMicroelectronics had returned to growth and, at the same time, that its shares were at the bottom of the CAC 40. The available information does not give details of the group's figures.

The facts
On 5 November 2026 at 10:56, mesinfos headlined that STMicroelectronics was returning to growth in the “third half-year 2026”. The headline refers to a half-year, which is probably an error for quarter, but the source does not allow us to confirm this. The headline alone gives no revenue, margin or pace of recovery.
The same day at 11:29, Idéal Investisseur described the shares as the CAC 40’s “lanterne rouge” (wooden spoon), down 20% in a month. In the material provided, the outlet does not state the starting date of this decline or the share price reached.
The two sources complement each other without contradicting each other: one refers to the growth of the business, the other to share price performance. Neither explains, in the extracts available, why the shares are falling despite this recovery.
Our take
My take: the contrast is striking, but it is not necessarily contradictory. A return to growth can disappoint if investors expected more, or if the outlook for the coming period is worrying. These are hypotheses; the sources do not confirm them.
A 20% fall in a month and last place in the CAC 40 on the day of publication show considerable nervousness around the stock. Without the quarter’s figures, management’s guidance or analysts’ views, it is impossible to say whether the sell-off is justified or excessive.
My opinion therefore remains without a firm view. I am not setting a price target, for lack of figures that could justify one.
Risks to watch
The information rests on two article headlines, with no detailed figures: a misinterpretation is possible, notably on the period (half-year or quarter). The recent sharp fall may continue if the group's outlook disappoints. Conversely, a rapid rebound remains possible if the recovery is confirmed, which makes any short-term reading fragile.
