Most people predicted it would drop down again and that is still a possible outcome. The best idea would have been to put money in on the last dip and then sold half out at around this point in case it dipped back down. When you are waiting for the perfect bottom based on TA that is only probable, not definite, you are setting yourself up for a disaster.
Most people were expecting a bounce up from the 9k level to about 11k, then a drop to 8k. there is a ton of resistance at 12k so i would look to see if it breaks through and holds
