Insiders Could Have Profited By Holding onto Uni-Bio Science Group Shares Despite 11% Drop

Simply Wall St · 1d ago

Even though Uni-Bio Science Group Limited (HKG:690) has fallen by 11% over the past week , insiders who sold HK$187m worth of stock over the past year have had less luck. Insiders would probably have been better off holding on to their shares given that the average selling price of HK$0.12 is still lower than the current share price.

While insider transactions are not the most important thing when it comes to long-term investing, we do think it is perfectly logical to keep tabs on what insiders are doing.

The Last 12 Months Of Insider Transactions At Uni-Bio Science Group

Over the last year, we can see that the biggest insider purchase was by insider Yi Wah Lau for HK$185m worth of shares, at about HK$0.12 per share. That means that an insider was happy to buy shares at above the current price of HK$0.079. While their view may have changed since the purchase was made, this does at least suggest they have had confidence in the company's future. We always take careful note of the price insiders pay when purchasing shares. As a general rule, we feel more positive about a stock when an insider has bought shares at above current prices, because that suggests they viewed the stock as good value, even at a higher price. Yi Wah Lau was the only individual insider to buy shares in the last twelve months.

Kingsley Leung sold a total of 1.58b shares over the year at an average price of HK$0.12.
