Dingyi Group Investment's recent revenue performance may not meet market expectations, causing a dip in the P/S ratio. The company's medium-term revenue trends are less appealing compared to the industry's projected 20% growth. Shareholders might be uneasy holding a stock they believe will lag behind the industry.

Despite Dingyi Group Investment's share price rise, its P/S ratio still trails most firms due to disappointing revenue trends over the past three years. Investors believe the potential for revenue improvement doesn't warrant a higher P/S ratio. If recent revenue trends persist, a share price reversal seems unlikely.

Investors doubt Dingyi Group's sustainable growth potential despite robust revenue, anticipating future revenue fluctuations which press down the P/S ratio.
