The impact of shareholder share reduction on the valuations of small and mid-cap pharmaceutical and chemical stocks can be analyzed from the following five dimensions:

A 3% share reduction will add approximately

worth of tradable shares to the market. For Lanfeng Bio-chemical, which has an average daily trading volume of about 24 million shares, this is equivalent to adding approximately . Concentrated selling in the short term will break the original supply-demand balance, exerting direct pressure on the stock price.

Shareholder share reduction is usually interpreted by the market as the following signals:

• Insider Signaling Theory
  : As insiders of the company, shareholders may possess unfavorable information unknown to the market
• Signal of Lack of Confidence
  : Even neutral reasons such as “capital needs” will arouse market suspicion about whether shareholders are “bearish” on the company
• Herd Selling
  : Share reduction announcements often trigger panic selling

|

The liquidity characteristics of small and mid-cap stocks make the impact of share reduction more significant:

• Lanfeng Bio-chemical has an average daily turnover of approximately RMB175 million
• The 3% share reduction amounts to approximately RMB0.82 billion, accounting for
  47%
  of the average daily turnover
• Insufficient liquidity may lead to a
  liquidity discount
  , and the actual reduction price may be 3%-5% lower than the market price

|

During the share reduction period, the market usually assigns a certain valuation discount to the relevant stock:

• Information Asymmetry Discount
  : The market is concerned that the reducing party holds undisclosed information
• Time Pressure Discount
  : The reducing party needs to complete the sell-off within the specified timeframe
• Block Trading Discount
  : Block trades are usually executed at a 2%-5% discount

|

Lanfeng Bio-chemical currently has weak fundamentals, which will amplify the negative impact of the share reduction:

• The company is in a state of sustained losses, with an ROE of -2413%
• Both the current ratio and quick ratio are below 1
• Weak fundamentals make the stock price more susceptible to sentiment and capital flow influences
