LPKF Laser: The All-Time High, the Short Attack, and the Earnings Reality

LPKF stock skyrocketed 294% year-to-date on LIDE technology hopes, but short sellers are increasing bets as Q1 revenue slumped and volatility remains extreme.

LPKF Laser & Electronics has become one of the most dramatic stories on the German market this year. The stock surged from penny-stock territory to an all-time high of EUR 29.20 on Monday, only to give back roughly 17 percent of that peak by Thursday. In a volatile session, the shares swung between EUR 23.70 and EUR 24.20, ending with a net loss of 5.2 percent on the day. Yet even after the pullback, the year-to-date gain stands at a staggering 294 percent.

That rally rests on soaring expectations for LPKF's LIDE (Laser Induced Deep Etching) technology, which is being pitched as a key enabler for glass substrates in advanced chip packaging. This week the company is showcasing LIDE at the iTGV Forum in Wuxi, China, and also at the SPEXA space fair in Tokyo. The market, however, is showing signs of impatience: the conference tour alone has not been enough to confirm the story.

Short sellers are growing bolder. Voleon Capital Management has increased its net short position to 2.13 percent, up from 1.70 percent at the end of April. Marshall Wace also holds a registered short position. The pattern suggests that at least some sophisticated investors are betting that the stock's price has outpaced the company's operational reality.

The first-quarter numbers give ammunition to the bears. Revenue slumped 32 percent year-on-year to EUR 17.1 million, while EBIT swung to a loss of EUR 6.9 million from a loss of EUR 3.9 million in the prior-year period. Adjusted EBIT came in at minus EUR 5.7 million. The "North Star" restructuring program added costs, and the legacy solar business remained a drag.

Order input, though, offers a counterpoint. LPKF reported EUR 24.1 million in new orders, yielding a book-to-bill ratio of 1.4 — a reading above 1 that normally signals growth momentum. Management sees particular progress in the semiconductor and advanced packaging segments. The full-year guidance targets revenue of EUR 105 million to EUR 120 million, with an adjusted EBIT margin ranging from minus 3 percent to plus 4.5 percent. Notably, the guidance excludes any potential volume orders from the advanced packaging space.

The technical picture adds further caution. The 14-day Relative Strength Index has dropped to 25.5, deep in oversold territory after a rally that lifted the stock sixfold from its December low of EUR 5.35. Annualized volatility stands at 150 percent, meaning daily swings of 5 to 10 percent are routine. The 200-day moving average sits at EUR 8.88, while the 50-day average of EUR 15.31 is already far below the current price. Such extreme divergence often presages a sharp consolidation.

Several events will test the narrative. The annual general meeting takes place on June 4 (registration closes today at midnight CEST), followed by CEO Klaus Fiedler's appearance at the SdK investor forum on June 18. The half-year report is due on July 23. Until then, the market will be watching for concrete LIDE contracts — not just trade-show presence — to justify the valuation.

For now, LPKF finds itself in an unusual tug-of-war. The stock has delivered a life-changing return for early buyers, but the fundamental proof points are still being assembled. Short sellers are betting that the hype has run ahead of the numbers. The next few weeks will show whether the company can convert its technology roadshow into revenue that matches the newfound gravity of its share price.
