At his peak, Dr. Sun held substantial positions in Zentalis' stocks, reflecting his deep commitment to the company. His insider trading showed fluctuations in his holdings, peaking at around $210.94 million in December 2020. Following that, over the next couple of years, the value dropped significantly, with values reaching as low as $30.21 million by late 2023. This decrease illustrates the volatile nature of the biotech field, but it also underscores Dr. Sun's hands-on investment in Zentalis, playing a critical role in its growth and challenges. After his departure, he retained some vested interests, indicating a continued belief in the company's potential.
