The strategy of buying PubMatic (PUBM) shares after they reached a recent high and holding for 1 week yielded moderate returns over the past 5 years, with a 7.56% annualized gain.

Recent High Point Identification: The backtest assumes that the recent high point was identified correctly, allowing for entry at an optimal price.

Short-Term Volatility Capture: Holding PUBM shares for 1 week captured short-term volatility, as evidenced by the 7.56% annualized gain. This suggests that the strategy benefited from normal market fluctuations.

Missed Broader Rallies: The strategy missed the broader rallies in PubMatic's stock, which could have led to higher returns if held for longer periods. This is a common limitation of short-term holding strategies in high-growth tech companies.

Annualized Return Calculation: The 7.56% annualized return was calculated based on the assumption that the strategy was executed on a weekly basis, taking into account the compounding effect of returns over the 5-year period.

In conclusion, while the strategy of buying PubMatic shares after they reached a recent high and holding for 1 week provided a modest return, it may not have fully captured the potential of the company's growth. Investors should consider both short-term and long-term perspectives when evaluating high-growth tech stocks like PubMatic.

PubMatic's recent stock price movements can be attributed to several key factors highlighted in its Q1 2025 earnings report. The company exceeded its guidance with a 21% year-over-year revenue growth, driven by significant increases in Connected TV (CTV) and Supply Path Optimization (SPO). Despite a 4% decline in total revenue due to the impact of a large DSP buyer and political advertising, PubMatic demonstrated financial resilience with no debt and a strong financial position.

CTV revenue surged by over 50% year-over-year, while SPO accounted for a record 55% of total activity. This strategic focus on efficient and high ROI solutions positions SPO to potentially reach up to 75% of the business in the long term. The company's share repurchase program was also increased by $100 million, reflecting confidence in its future and commitment to enhancing shareholder value.

While the earnings report was well-received, with the stock closing up 9.56% and continuing to rise in after-hours trading, there are concerns about macroeconomic uncertainty and its potential impact on ad spend, particularly in verticals like technology and automotive. These factors collectively contribute to the changes in PubMatic's stock price, reflecting both the company's strong performance in key areas and the challenges it faces.
