1. I'm just a hater that can read a chart. I'm not a financial advisor. Do your own research and do what you want with your bread.
2. Anybody giving you precise dates about when a security is definitely going up or down is capping. At best, you can plan your moves based on when the stock hits your entey/exit price and not be married to a time span.
3. I prefer to use Moving Averages to find resistance and support levels and when they crossover on significant volume as buy/sell signals. Right now AMC is trading below the 50-day EMA and trending down towards the 100-day EMA. If it doesn't bounce off that, it might not find support again until it hits the 100-day SMA.
