It is scary, because it is so easy

No news, no catalyst and BOOOOOOM! we have 17.x% return in 3 trading days!!!

I bought PANW (Palo alto network) because I thought post earnings the stock sold a lot and it might bounce back a bit. But I had no idea that it will bounce back 17.x% in 3 trading days!!! When you can make money so easily, you should be worried.
