Sorry, didn't put this up earlier but it's still valid.
SGMO has bearish divergence between 11/14 last year and 01/13 this year (white arrows on chart and RSI ). Also as usual, RSI shows signal for selling (overbought).
The price also happens to be at the downtrend channel resistance. The volume profile shows increased more seller-to-buyer ratio since 01/17.
Initial target should be $3.10. Ideal target for $2.70
