Westlake Corporation reported a non-GAAP EPS of $2.01, exceeding market expectations of $1.89 by $0.12, and announced a revenue of $3.27B, surpassing the forecast of $3.25B by $20M, resulting in an earnings surprise. Following a 9% surge during intraday trading on August 4, the stock underwent a two-day correction on August 5-6. The direct catalyst was the 8-K (Item 2.02 earnings announcement) filed on August 4. A 10-Q regular report was filed on August 5, along with a 8-K (Item 8.01 other events) on July 29, but no unusual risks were detected, classified as INFO alert level. A significant increase in industrial goods theme news (171 cases vs. 35 cases, rising) and an S-Class conversion rate of 25.7% created a favorable environment. The entry point closing price of $79.57 on August 6 is just below the resistance level of $79.84 and more than 16% above the support level of $68.48. The RSI at 23.6 indicates oversold conditions, with a misalignment of moving averages and a trading volume of 1.77 times, interpreted as an attempt to rebound from oversold conditions within a downtrend, accompanied by volume. The profit-taking target is set at $79.84 (resistance level), and the stop-loss at $68.48 (support level). The actual performance recorded an OVERHIT of 13.8% compared to the forecast of 2.5%. The failure to transition to a trend-following strategy after breaking through the resistance level led to an underestimation of profits. In future earnings surprise stocks, upon breaking through resistance levels, a trailing stop or partial profit-taking will be applied instead of a fixed profit target, and the betting weight for trend transitions will be increased when volume and theme momentum are strong, even if the moving averages are misaligned. The condition of 'confirmation of breakout' will be maintained before entry, but the holding strategy will be expanded from 'day trading' to 'swing trading' after the breakout. The shallow correction following the earnings surprise on August 4, which was supported by the 20-day moving average and subsequently rose again, needs to be corrected from the view of 'stopping at the resistance level after a short-term rebound.' The trading volume of 1.77 times and the theme momentum suggested continued buying interest, but the profit-taking target was set conservatively. From the next trade, upon confirming the breakout of the resistance level, a first profit-taking of 30% will be executed, with the remaining 70% using a trailing stop based on the 20-day moving average or the previous high. Until the moving averages align positively, the position size will be limited to 50%, but additional entries will be allowed upon confirming strength after the breakout. A significant increase in theme news (rising) and a conversion rate of over 25% will be weighted for sector momentum. If there are no unusual matters other than the Item 2.02 earnings announcement in SEC filings, a neutral stance will be maintained, and the stop-loss will be adjusted upward immediately upon insider selling/dilution disclosures. A gap analysis of 'forecasted return vs. actual return' will be mandatory during daily reviews. Cases of OVERHIT will be reflected in the evolution of profit-taking strategies by reviewing 'why it rose more.' In cases of FAILED, the focus will be on detecting exit signals before touching the stop-loss. Weekly updates of personal trading statistics (win rate, profit-loss ratio, OVERHIT ratio) will be established to automate strategy weight adjustments. Technical interpretation at the entry point on August 6: The RSI at 23.6 suggests a possibility of a short-term rebound, while the misalignment of moving averages indicates a continuation of the medium-term downtrend, and the trading volume of 1.77 times confirms concentrated buying interest post-earnings. In summary, it is a phase of 'attempting to rebound from oversold conditions within a downtrend, accompanied by volume.' Basis for entry judgment: The current price of $79.57 is positioned just below the resistance level of $79.84, signaling an imminent breakout, with a 16% margin of safety from the support level of $68.48. The increase in volume during the correction phase following the earnings surprise is interpreted as an attempt to rebound. However, due to the misalignment of moving averages, it is reasonable to enter only after confirming the breakout of the resistance level. Scenario: If the resistance level of $79.84 is successfully broken, a first profit-taking at $79.84 will be executed, followed by a transition to trend-following (trailing stop at the 20-day moving average), and a stop-loss at $68.48 will result in a complete sell-off if the support level is breached. Confirmation of the breakout is essential before entry. Regulatory disclosure: The stock price surged directly due to the earnings announcement in the 8-K (Item 2.02, 7.01, 9.01) on August 4, while the 10-Q regular report on August 5 and the content of the 8-K (Item 8.01) on July 29 are unknown, but no unusual risks were detected, classified as INFO alert level. As it is a routine disclosure, no strategic changes are necessary due to risks (neutral). Theme momentum: The number of news articles related to industrial goods has increased significantly in the past 7 days to 171 (from 35 in the previous 7 days, rising), and the S-Class conversion rate of 25.7% indicates favorable conditions for both news growth and stock price transition probability. Reference cases: No similar successful cases provided. There are no comparable top-performing cases available. Diary title: I thought it would end with a failure to break through the resistance level after the earnings surprise, but it closed with a 13.8% big profit. Diary review: The actual return of 13.8% compared to the forecasted return of 2.5% (assuming a 0.3% increase based on the resistance level of $79.84) resulted in an OVERHIT. The potential for further gains after breaking through the resistance level was underestimated. The shallow correction following the earnings surprise on August 4, which ended and was supported near the 20-day moving average, was mistakenly viewed as 'stopping at the resistance level after a short-term rebound.' The trading volume of 1.77 times and theme momentum (surge in news, conversion rate of 25.7%) indicated continued buying interest, but the profit-taking target was set conservatively. Future plans: In earnings surprise stocks, upon immediate breakout of the resistance level, 'trailing stops' or 'partial profit-taking (30% at the first resistance level, 70% for trend following)' will be applied instead of a 'fixed profit target.' Even if the moving averages are misaligned, the betting weight for trend transitions will be increased when there is a surge in volume and strong theme momentum. The condition of 'confirmation of breakout' will be maintained before entry, but the holding strategy will be expanded from 'day trading' to 'swing trading' after the breakout.
