Following my previous post regarding $AMC Entertainment(AMC)$:

It is noticed that this stock is going strong!

Note how both top & bottom (especially bottom) line of the bollinger bands is maintaining a fairly steep line upwards.

MACD is also constant on the rise.

RSI still has some space towards ceiling.

So we can be certain, it is ok to hold on to this stock (for long-term investing it is ok to keep; for swing traders, wait till the next converge of the MACD lines before selling)
