The strategy of buying ADCT shares after they reached a recent high and holding for 1 week yielded moderate returns over the past 5 years, with a 4.61% annualized gain.

Market Context: The performance of ADCT shares is influenced by upcoming data catalysts related to ZYNLONTA combinations, which are expected to drive future growth and foster positive investor sentiment. Additionally, analyst ratings have been upgrading, supporting the stock's recent performance and indicating a bullish sentiment towards the company's future prospects.

In conclusion, while the strategy of buying ADCT shares after they reached a recent high and holding for 1 week provided some stability and gained 4.61% annually, it underperformed the broader market's gains over the past 5 years. The company's future growth prospects, however, appear positive due to data catalysts and analyst sentiment.

ADC Therapeutics' stock price has been significantly influenced by recent regulatory approvals. The company's CD19-directed antibody-drug conjugate (ADC) ZYNLONTA (loncastuximab tesirine-lpyl) received accelerated approval from the FDA and conditional approval from European authorities. These approvals are expected to enhance market access and generate revenue, positively impacting ADCT's stock price.

Additionally, ADC Therapeutics has been highlighted as one of the best penny stocks to watch in June 2025, with a price of $2.50 and a one-month return of 88.0%. This recognition indicates substantial interest and trading volume, which could further drive the stock price upward.

Anticipation of upcoming clinical trial news and a potential biotech breakout are also contributing factors to the stock's recent performance. Investors are eagerly awaiting developments that could further bolster ADCT's market position and financial prospects.
