United Laboratories International Holdings VP & Executive Director Xian Hong Zou Sells 57% Of Holding

We'd be surprised if The United Laboratories International Holdings Limited (HKG:3933) shareholders haven't noticed that the VP & Executive Director, Xian Hong Zou, recently sold HK$2.3m worth of stock at HK$15.11 per share. Equally important, that sale actually reduced their holding by a full 57% which hardly makes us feel bullish about the stock.

The Last 12 Months Of Insider Transactions At United Laboratories International Holdings

Notably, that recent sale by Xian Hong Zou is the biggest insider sale of United Laboratories International Holdings shares that we've seen in the last year. That means that even when the share price was below the current price of HK$15.90, an insider wanted to cash in some shares. When an insider sells below the current price, it suggests that they considered that lower price to be fair. That makes us wonder what they think of the (higher) recent valuation. While insider selling is not a positive sign, we can't be sure if it does mean insiders think the shares are fully valued, so it's only a weak sign. We note that the biggest single sale was 57% of Xian Hong Zou's holding.

Insider Ownership

Another way to test the alignment between the leaders of a company and other shareholders is to look at how many shares they own. We usually like to see fairly high levels of insider ownership. It appears that United Laboratories International Holdings insiders own 0.9% of the company, worth about HK$272m. This level of insider ownership is good but just short of being particularly stand-out. It certainly does suggest a reasonable degree of alignment.

So What Does This Data Suggest About United Laboratories International Holdings Insiders?

An insider sold stock recently, but they haven't been buying. And even if we look at the last year, we didn't see any purchases.
