The Globe and Mail reports in its Saturday, Feb. 18, edition that Northern Dynasty Minerals ($2.97) directors buy as stock falls on short-seller claims. The Globe's Ted Dixon writes in the Whose Buying and Selling column that on Tuesday, Kerrisdale Capital Management LLC published a report claiming that Northern Dynasty Minerals' Pebble deposit in Alaska is not commercially viable. Kerrisdale had a short position in Northern Dynasty and would benefit if the share price fell. Fall it did, plunging 21.9 per cent on the news. As the stock dropped, two directors spent $87,000 buying shares. Generally, according to Mr. Dixon, it is a positive contrarian sign to see insiders buying as a stock falls on bad news as it may suggest the market overreacted. The Globe reported on Feb. 16 that Northern Dynasty was upgraded to "speculative buy" from "hold" by TD Securities analyst Craig Hutchison. He reiterated his $5 target, which matched the analyst average share target. The shares were then worth $2.98.
