LightOn Stock Rebounds by 13% but Remains Down Over the Year

LightOn stock surged by 12.39% to €3.81 at mid-session on Euronext Paris, after closing at €3.36 the previous day. The stock is rebounding from its support level, while the CAC 40 is down by 0.49% and the SBF 120 has fallen by 0.44%. Over the year, the stock is still down by 81.49%.


LightOn Stock Rebounds by 13% but Remains Down Over the Year

Technical Rebound from Support in a Pronounced Oversold Zone

The stock has rebounded from the support level at €3.36, which was Wednesday's closing price. The 20-day RSI indicates significant overselling, consistent with the bearish momentum over the last few weeks (-34.45% over three months).
The rebound today must be viewed within a deteriorated technical context. The price is still below its three moving averages: the MM20 at €4.33 (a gap of -12.64%), the MM50 at €5.17, and the MM200 at €6.95. The identified resistance at €5.92 remains distant. The MACD is still in negative territory, with a line at -0.47 and a signal at -0.40. Today's surge improves the weekly performance (7 days +1.60%) but is not enough to reverse the underlying trend.

The rebound occurs as Nvidia reported a first-quarter revenue of $81.6 billion, up 85% year-over-year, with an adjusted gross margin of 75%. The data centers segment, at $75.2 billion (+92%), highlights the scale of investments in artificial intelligence infrastructure.
LightOn, specializing in generative AI for businesses, indirectly benefits from this positive signal sent to the entire European AI ecosystem. The stock had already attempted a rebound on May 14 at €3.84 before falling back to its support. The crossing of the MM20 at €4.33 will be the next technical level to watch.
