Till recently PS4 was tracking above PS2 in year to year sales. PS2 had a super long tail combined with and incredibly low price (both hw & sw) which helped it in smaller growing markets (+ piracy too)
Technicals wise avoid it right now. Trading well above 15% in 20 ema ( even more in 50 ema). Wait for slightly lower levels as it might retest it's breakout. If you still want to enter keep 700-710 as your SL with targets 825 & 925.
