Background of OISolution's Surge
On May 4, 2026, OISolution's stock price exhibited significant volatility by surging over 20% during trading hours. This is interpreted not simply as the announcement of positive news, but rather as a rise driven by expectations surrounding optical communications, AI data centers, and external light sources for CPO, resulting in a supply-demand-driven increase.
The current stock price is 46,500 won, a 20.16% increase. The trading volume surpassed 1.65 million shares, with the trade value reaching approximately 72.9 billion won. Following a significant rise from the lows, this is a typical surge pattern as it attempts to break through the previous high, reflecting a concentration of short-term trading funds.
Expectations for Earnings Turnaround
The primary reason for this increase is the expectation of a recovery in earnings in 2026.
As highlighted by securities experts, the following factors are noteworthy: recovery in FTTH optical transceiver sales, cost improvements through the internalization of LD chips, and an increase in revenue related to data centers.
The outlook for future earnings is optimistic, with expected sales ranging between 80 billion to 120 billion won and operating profit projected at 6 billion to 7 billion won. The possibility of a shift to profitability is also raised.
In particular, the market is showing a trend of reassessing the company from its previous image as a 5G equipment stock to a candidate for the optical connectivity value chain of AI data centers.
Benefits from AI Data Centers
The current industry environment is exhibiting positive trends. Big tech companies like Alphabet, Meta, and NVIDIA are aggressively increasing their investments in AI infrastructure.
Key changes include a shift in bottlenecks of data center networks from GPU-centric systems, with an expansion of optical communication-based connections instead of electrical signals. Furthermore, a transition from traditional transceiver structures to CPO (Chip-based Photonics Integration) structures is taking place.
The essence of the AI era is shifting from simple computational capability to connection performance between servers. This trend suggests a new direction for technological advancement.
Optical transceivers, laser light sources, and switching networks are emerging as key infrastructures. These elements are further enhancing OISolution's investment attractiveness.
Global Optical Communication Trends
Global optical component companies are showing positive results.
Lumentum reported a 65% increase in revenue, with a significant increase in demand for CPO and OCS observed.
Coherent also completed 72% of its business in data centers and continues to see steady growth in its telecommunications division.
In particular, the transition from 800G to 1.6T transceivers, expansion of InP-based light source production, and rising demand for optical interconnects for AI servers are happening simultaneously. This change indicates that the entire optical communication sector is entering a structural growth phase.
Investment Risk Assessment
The current stock price reflects significant expectations.
The primary risk factors are as follows: first, the supply situation is still unconfirmed. Second, actual supply contracts with big tech companies have not been verified.
Additionally, there have been warnings of overheating in the short term, and investment alerts have been repeatedly designated and reassigned, which should be noted.
Verification of earnings is essential.
First, attention should be paid to how much the first quarter loss will reduce.
Second, an improvement in gross profit margins is expected in the second quarter.
Third, there is a possibility of order acquisition through customer testing in the third quarter.
The current situation is based on a rise driven by potential, and the verification through actual figures and contracts will be a key factor.
Conclusion and Investment Strategy
OISolution's recent surge is the result of multiple contributing factors. The recovery of the FTTH market, internalization of LD chips, growth of data centers, and the global increase in AI investment have all had a positive impact.
To summarize the key points, there are expectations for benefits in AI data centers and optical communications in the mid to long term. On the other hand, in the short term, there is a possibility of entering a heated cycle, which could increase volatility. Ultimately, how earnings and orders materialize will be crucial.
In conclusion, OISolution is not just a simple communication equipment company but an important candidate for re-evaluation in the transition to AI infrastructure. At this point, rather than pursuing aggressive buying, a strategy to verify earnings and respond to market corrections is needed.
