The Insider | Kangda and Tech Pro bosses boost stakes in active week

Buying by directors rose for a fifth week last week, based on filings to the exchange, while selling surged for a third week.

A total of 37 companies recorded 154 purchases worth HK$208 million against 23 firms with 103 disposals worth HK$513 million.

The number of companies and trades on the buying side were up from the previous week's five-day totals of 25 firms and 124 purchases. The buy value, however, was down from HK$324 million. The sales side, on the other hand, was sharply up from 12 companies, 28 disposals and HK$64 million the week before.

Meanwhile, buy-back activity was high for the fourth consecutive week with 20 companies posting 71 repurchases worth HK$111 million. The number of firms and trades were consistent with the previous week's five-day totals of 24 firms and 94 trades. The value, however, was sharply down from HK$222 million.

There were several significant purchases last week with insider acquisitions in Kangda International Environmental and Tech Pro Technology Development. There were more bullish signs in Ozner Water International Holding and Playmates Holdings with buy-backs and director purchases in them.

Chairman and founder Zhao Juanxian recorded the first trade by a director in wastewater treatment facilities investor Kangda since the stock was listed in July with 900,000 shares purchased on March 27 at HK$3.37 each. The trade increased his holdings to 53 per cent of the issued capital.
