Listen to the news

Last week, South Manganese Investment Limited (HKG:1091) insiders, who had purchased shares in the previous 12 months were rewarded handsomely. The shares increased by 12% last week, resulting in a HK$247m increase in the company's market worth, implying a 114% gain on their initial purchase. As a result, the stock they originally bought for HK$328.3m is now worth HK$701.5m.

Although we don't think shareholders should simply follow insider transactions, logic dictates you should pay some attention to whether insiders are buying or selling shares.

The insider Xuming Chen made the biggest insider purchase in the last 12 months. That single transaction was for HK$184m worth of shares at a price of HK$0.22 each. Although we like to see insider buying, we note that this large purchase was at significantly below the recent price of HK$0.47. Because the shares were purchased at a lower price, this particular buy doesn't tell us much about how insiders feel about the current share price.

In the last twelve months insiders purchased 1.51b shares for HK$328m. But they sold 151.00m shares for HK$47m. In total, South Manganese Investment insiders bought more than they sold over the last year.
