"When to sell?" Sell when most are buying. Sell when you wouldn't want to buy it. Sell when the chart looks "top heavy". Sell when it hits your "stop loss". Sell when all the message boarders are screaming "BUY". Sell when you get a margin call. Sell when selling gives you peace of mind. Sell before they release earnings. Sell when it spikes on good news. Sell when all the bashers have totally disappeared. Sell when it starts back down (not while it's going up). Sell when your trading plan calls for you to sell.
