CMG, CROX, LYV: I tried to diversify, but all of my stocks went down by 10%

I sold my ATVI stock and decided instead of putting it all in one stock let me diversify into 4 stocks. I put 1/4 each in CMG, CROX, LYV, and TTWO.

CMG, CROX, and LYV all went down by +10% so what was the point of diversifying if they all went down. Also what do you think about CMG, CROX, and LYV
