I agree. I'm not too fond of technical analysis. I think, for the most part, they are self fulfilling prophecies or at best, a coin flip. Most technical indicators, like a 'Head and Shoulders' or 'Cup and Handle' or 'Flag', don't have predetermined time frames. So a lot of times you kinda have to squint to interpret them, and if they don't fit into your interpretation, you just widen the timeframe.
A 200/50 Golden cross is different. It has a predetermined time from so there is no interpretation about it. It just is what it is. And what it is, is one of the strongest indicators of a bull run there is.
If anyone is on the fence about jumping into a stock, and willing to wait a couple months, there really is no better time than to use the golden cross to jump in.
And no, this doesn't make a stock skyrocket. It sets up a long-term uptrend that the stock is very likely to follow. And that is exactly what has been happening since it crossed on the May 22nd/23rd. This should continue steadily upwards for at least a few months, IMO
