If you still believe in NOT.V after all that years ... I wouldn't exit on an intraday pop .. or a runup from multi-year lows over a couple of days (based on fundamental speculation and a potential turnaround).

However - good risk management could also be to set a stop loss for a part of your shares ... if you are "in the money" it also never hurts to take 5-10% off... especially if you need some liquidity or think you can buy shares back lower.

If your position size hurts - it is probably too big.

And please remember - no one ever went broke taking a profit too early!
