Backtest Analyses

Stock Backtest: ISSC's Negative Earnings Momentum

Following an earnings miss, Innovative Solutions and Support has historically seen a sharp and consistent drop in stock price. According to the provided backtest data, ISSC has recorded a 0% win rate in the 3, 10, and 30-day periods post-earnings miss, with a severe 30-day return of -26.06%. These results indicate that the market reacts poorly to ISSC's earnings underperformance, typically triggering investor sell-offs and prolonged weakness in the stock. The data suggests a clear pattern of investor disappointment, likely rooted in unmet expectations and recurring performance inconsistencies.

Industry Backtest: Aerospace & Defense Sector Shows Resilience

In contrast to the sharp ISSC decline, the broader Aerospace & Defense sector demonstrates a more resilient and muted response to earnings misses. The backtest of 109 industry-wide earnings events shows no significant impact on stock returns, with a maximum return of 3.62% observed 53 days post-event. This suggests that the market in this sector either anticipates or absorbs earnings shortfalls without major repricing, potentially due to stable demand, long-term contracts, or macroeconomic insulation.

Driver Analysis & Implications

ISSC's earnings shortfall appears to stem primarily from its high operating costs, particularly in sales and general administration, which are eating into margins. While the company continues to invest in R&D ($3.03 million), the financials do not yet reflect a strong payoff from these investments in terms of higher revenue or profit growth. The lack of improved operating leverage and the failure to exceed revenue expectations likely triggered the negative market reaction.

At a macro level, the Aerospace & Defense sector remains relatively insulated from broader market volatility, as evidenced by the industry's backtest results. However, this resilience does not translate to ISSC, which may be lagging behind due to operational inefficiencies or a lack of competitive differentiation.

Investment Strategies & Recommendations

For short-term investors, the data suggests caution when it comes to ISSC. The historically poor returns following earnings misses imply that the stock may remain range-bound or continue to underperform in the near term. Short sellers or those with exposure may consider hedging or reducing positions until the company shows signs of operational improvement or better-than-expected guidance.

Long-term investors may want to wait for clearer signals before committing. ISSC’s continued investment in R&D could position it for future growth, but this requires management to effectively control costs and demonstrate consistent earnings performance. Watching the next earnings report and any guidance for Q4 2025 will be key for reassessing the company’s trajectory.

Conclusion & Outlook

Innovative Solutions and Support’s Q3 earnings miss has triggered a clear and historically consistent negative market reaction, contrasting with the broader sector’s resilience. While the company maintains a positive earnings base, the drag from high operating expenses and underwhelming revenue performance has dented investor confidence.

The next catalyst for ISSC will be its Q4 2025 guidance and earnings performance. Investors should monitor whether the company can stabilize costs, grow revenue more effectively, and deliver on its R&D-driven growth strategy. Until then, a cautious approach is recommended given the historical volatility seen in the wake of ISSC’s earnings reports.
