There never has been, to my knowledge, a high short position in Noront. Nor do you find day traders involved during times of low trading volume.
While it might be comforting to 'blame' someone for both the share price decrease over past while in reality it's just the way the market works and interprets share value from day to day. All junior exploration including Noront will be subject to what seems to be irrational swings in value.
Presently, I feel, price is beaten down well beyond rationality so any change in perception of Noront's prospects will be reflected in a sharp upside correction. Staying higher will depend upon assays and drill results which we just have to wait for.
US Market Index might be OK today but US Dollar sharply down against Euro and even Canadian Dollar. Expect more money flowing into commodities and yes even Junior Exploration companies.
