After a monster surge of over 35% in the last few months, Gilead Sciences (NASDAQ:GILD) put in a topping tail on Friday. Topping tails are bearish technical signals alerting investors to likely price reversal. Sure enough, Gilead Sciences fell on Monday. As an investor, I love Gilead Sciences, however the key is what entry price do I want to buy? The answer can be found in the stock chart. Once Gilead Sciences falls back to $76.50, it becomes a strong buy. There is a huge amount of technical support at that price.
