Soitec stock drops 21% in one week and slides below its 50-day moving average

The Isère-based semiconductor substrate manufacturer extends its profit-taking phase on Monday. The decline occurs in a Paris market clearly oriented downwards, following weekend violence and renewed tension over French debt.


Soitec stock drops 21% in one week and slides below its 50-day moving average

A week of correction that erases the gains made on moving averages

Soitec stock declines 1.71% to €126.35 during the session, while the SBF 120 falls 1.33%. The stock has lost 21% over seven days and now trades below its 20-day moving average (€151.50) as well as its 50-day moving average (€135.09), a gap of 6.5% with the latter. It nevertheless remains 28% above its 200-day moving average, at €98.71, a legacy of a surge of more than 230% over one year.

The RSI at 38.6 reflects buyer exhaustion over recent sessions, while the €123 support level is less than 3% below the current price. The MACD, which has crossed below its signal line, accompanies this movement.

In a Paris market under pressure following weekend violence, the CAC 40 loses 1.36% and the ten-year OAT remains close to 4.8%, with a spread of 1.37 percentage points over the German Bund. Soitec is not among the largest declines in the index, but continues a retreat that began last week. According to the consensus of analysts surveyed, the stock is trading at approximately 160 times expected earnings for the current fiscal year and 35 times those for the following fiscal year.

The group announced on July 29 a share buyback program worth €358 million. The €123 support level is the next level to watch.
