Comments
Centurion stands out, with two executive directors purchasing 1.08 million shares worth approximately S$1.49 million. Nam Cheong and GuocoLand also saw insider accumulation. Meanwhile, BlackRock’s stake in Hutchison Port Holdings Trust reached the 5% substantial unitholder threshold.
However, insider buying is a signal, not a guarantee. Purchases do not automatically mean shares are undervalued. Buybacks can support earnings per share, but effectiveness depends on valuation and financial strength.
My takeaway: Watch insider purchases, earnings growth, and valuations. The opportunity lies not in following insiders blindly, but in understanding why they buy.
