I would agree but it does depend upon how much higher than a core position you are willing to go in order to 'play' the market.

Many would strongly suggest that you keep a core position in Noront and not trade this simply because catching the high/low and potentially missing a trading halt and immediately losing out on major change in share price.

Even if you time the sale right can you time the reentry price too? Maybe not that important to try to buy back in at the low as long as you get back and pocket the profit. Still it's nerve wracking to buy back on pull back and then watch share price drop further and takes almost as much patience as just staying long.

There is no rule of thumb or advice to assist in trading in and out, have to watch and try to recognise when share price seems to be overbought and subject to some drawback. Guess wrong and you could watch it turn around and run away.
