[LITE]

Shares of LITE, COHR, and AAOI surged after the Lumentum CEO announced that AI components are sold out through early 2029. If the stock price rises driven by favorable news on AI component demand and a bullish moving-average alignment, I will take full profit upon reaching the take-profit target of $1137.2. Conversely, if support breaks amid short-term volatility and the price falls below the stop-loss level of $832.11, I will immediately execute a stop-loss. I considered entering a long position in anticipation of the continuation of the upward trend, driven by a powerful positive catalyst—the Lumentum CEO's statement that AI components are completely sold out—as well as favorable technical indicators, including a closing price of 756.17 as of October 23, 2026, a +7.7% return over the past 7 days, an RSI of 65.4, and a bullish alignment of moving averages. At the time of entry, the RSI (14) stood at 65.4, indicating further upward momentum remaining before entering the overbought zone, while the moving averages maintain a bullish alignment. Trading volume came in at 1.04 times the 20-day average, representing average inflow, and the 7-day volatility recorded +7.7%. I entered the position based on the strong positive catalyst of the complete sell-out of AI components, a bullish moving average alignment, and an upward trend with an RSI of 65.4. However, the actual result fell far short of the projected 4.5% return, recording a -27.9% loss and receiving a FAILED rating. Although it was judged that the upward momentum would continue based on a volatility of +7.7% and 1.04x volume over the 7 days immediately prior to entry, it appears that the position failed to defend against volatility near the short-term peak and breached the stop-loss criteria. The failure of this trade demonstrates that even when accompanied by strong positive news and a bullish aligned moving average indicator, the volatility risks stemming from short-term surges were not sufficiently taken into account. In future trades, rather than relying solely on positive news, I will adjust to more conservatively observe price movements near stop-loss levels and support lines during periods of heightened volatility and strictly apply risk management.

Shares rose following the news that Lumentum, Qualcomm, and Corning have formed a partnership in the field of AI optical technology. To state the conclusion first, upon a rebound accompanied by increased volume, we will take profits if it reaches the resistance level of $1026.76, and cut losses if it breaks below the 20-day low support level of $784.47. To give you the conclusion first, the current stock price is positioned between the 20-day low support line and the high resistance line, so I considered entering with the expectation of a rebound accompanied by an increase in trading volume. RSI (14) stands at 53.4, indicating neutral momentum, moving averages are in a bullish alignment (short-term above medium/long-term), trading volume is at 2.25 times the 20-day average, and the fluctuation rate over the past 7 days recorded -5.9%. To give you the conclusion first, we entered the position targeting an expected return of 2.5%, anticipating a rebound based on the positive catalyst of an AI optical technology partnership, a 2.25-fold increase in trading volume compared to the 20-day average, and a bullish moving average alignment (정배열). However, the actual result was a loss of -11.5%, resulting in a FAILED rating. Although we aimed for a rebound between the 20-day low support line and high resistance line as the stock price plunged rapidly from 1,067.03 to 824.13 with a volatility rate of -5.9% over the 7 days immediately preceding the entry, we failed to account for the fact that the downward pressure and volatility already underway could not be fully overcome, ultimately leading to the stop-loss level. To begin with the conclusion, in future trading, even if trading volume increases and favorable news emerges, we will adopt a more conservative approach when evaluating expectations of a rebound from support levels during periods of sharp short-term declines, such as the downward trend (-5.9% volatility) observed over the past 7 days. In particular, rather than focusing solely on the position between support and resistance lines, we will adjust our execution plan to enter positions only after confirming that rebound attempts amid a downward trend technically lead to a definitive trend reversal.

The emergence of optical component-related stocks Lumentum and Coherent as top gainers in the S&P 500 demonstrates that investors continue to search for signs of demand along the AI data center supply chain amid concerns over a slowdown in spending. At the current stock price level, if short-term upward momentum leads to a test of the resistance level at $1026.76, we will consider taking profit; conversely, if the stock breaks down and shows signs of breaching the support level at $784.47, we will respond with a stop-loss. A buy may be considered given the recent 7-day steady candle flow and market interest in AI data center supply chain demand. Currently, the price is between the support and resistance lines shown; short-term upward momentum could lead to a test of the resistance line, but caution is required due to low trading volume. RSI(14) is at 45.5, indicating a neutral phase, and the moving averages are in a positive alignment. Trading volume is relatively low at 0.69 times the 20-day average, and the 7-day change recorded -1.0%. Although a projected return of 1.5% was anticipated, the actual result recorded a 14.1% increase, resulting in an OVERHIT rating. At the time of entry, we judged that caution was warranted due to a neutral RSI(14) of 45.5, a bullish moving average alignment (bullish fanout), and a relatively low trading volume at 0.69 times the 20-day average; however, the market's strong momentum regarding AI data center supply chain demand pushed past the resistance level and led to a sharp actual price surge. Despite the low volume, we failed to fully account for how the increasing trend in thematic news and expectations of supply chain benefits would drive stronger-than-expected buying pressure. In this trade, we approached the market conservatively because trading volume fell short of the 20-day average, causing us to miss a portion of the upward move. Moving forward, in phases where theme-related news trends are on the rise and supported by S-Class conversion rates, rather than simply being wary of low figures when interpreting volume indicators near resistance levels, we will more flexibly evaluate the overall supply-demand strength of the theme and the ripple effect of supply chain-related positive news, and apply this to the next trade by adjusting the profit-taking target price more dynamically.

Lumentum Holdings rose 10% amid a rally in optical networking stocks. Amid the optical networking rally, the upward trend will continue; once the take-profit target of $1026.76 is reached, I will take partial profits, and if the support collapses based on the candlestick pattern and falls below the stop-loss price of $784.47, I will cut losses for risk management. Prompted by Lumentum Holdings' 10% surge amid the optical networking rally, we are considering an entry. Looking at the technical indicators at the entry point, the RSI (14) is at a neutral level of 45.5, and the moving averages are in a bullish alignment (right-ordered array). Trading volume is at 0.69 times the 20-day average, and the volatility over the past 7 days recorded -1.0%. At the time of the prediction, a 3.5% return was forecasted based on news of a 10% surge amid the optical networking rally, positively aligned moving averages, and a neutral RSI of 45.5. However, it actually recorded a high return of 13.7%, resulting in an overheat determination. Even though trading volume was somewhat sluggish at 0.69 times the 20-day average, it was confirmed that the increasing trend of news across the theme and positive momentum pushed the stock price up much stronger than expected. Through this trade, we learned that the overall rising trend in theme-related news and S-Class conversion rate data can serve as a powerful booster during actual surges, going beyond mere numerical significance. In future similar theme upturns, even if trading volume is somewhat low, we will consider a strategy of slightly more flexibly raising split take-profit target prices when news momentum within the theme is strong.

Lumentum expects sales to more than double due to surging AI demand, and announced a positive earnings outlook and forecast. If I hold the position, I will take profit at $937.0 if the price breaks through the resistance line 937.00, and cut loss at $594.84 if the price drops to the support line 594.84 (based on the report's calculated values). Current price $820.59 is positioned midway between support and resistance lines, and considering the 7-day volatility rate of +17.3% and a 1.34x increase in trading volume, I considered buying on the judgment that upside potential exists. RSI(14) 48.2(Neutral), Moving averages misaligned (Low reliability), Trading volume 1.34 times the 20-day average, Recent 7-day price change +17.3% (Upward momentum) Compared to the predicted return of 3%, it recorded an excess return of 19.2%. The AI demand catalyst and upward momentum that served as the basis for the buy judgment were accurate, but the target return was set too low, leading to underestimation. It overlooked a strong rise near the resistance line, and excessively reflected the neutral alignment of RSI and MA. In the next trade, AI-related positive factors are assigned a higher weight, and the initial target profit target is raised to a more realistic level. Sudden trading volume surge and 7-day volatility are used as key entry signals, while position size is adjusted when moving average alignment is uncertain. The stop-loss line is maintained near the existing support line, while a partial profit-taking strategy is introduced for quick profit realization. TASK(2026-08-06) also shared AI demand keywords, resulting in similar buy judgments, and the stock recorded a 29.7% return. LITE(2026-09-09) also achieved a 19.2% return using the same AI demand-related keywords and associated market catalysts. VEEE(2026-07-16), while not directly similar, demonstrated a high return of 451.7% and serves as a top-performing case for reference.
