If it breaks 621.5 go long with taking small targets, remember a strong resistance at 621.5. Sell very cautiously and use a very strict stop-loss. While there is a strong resistance at 621.5, the stock is looking strong because it retraced fully and broke the trend line upwards with high volume. Well their can be consolidation in the stock now, maybe a pullback can come too but the stock looks strong for long term investment.
