With ETH not responding to the recent short term price action in other AltCoins and BTC, I went in search of reason(s) why. Ultimately this lead me to a comprehensive data source with all of ETH's price history. This then led to a full revision of the wave count for ETH. Here's the bad news, The recent high near 400 marked the top of a 5 wave structure completing wave (1). That means ETH has entered wave (2). Boo hoo, a terrible (2).
It appears that wave A of (2) may have completed with the retrace of 61.8% of the overall gain since ETH began trading. The wave B of (2) bounce is struggling to gain traction, will likely be minimal, and will take time. How much time is anyone's guess. All that is in prelude to wave C of (2), which could take ETH lower still, potentially to 100 area (or lower), if the final lower will reach to the 78.6% retracement level.
Exit the majority of any positions during this bounce, or seek to find a pair trading against ETH, or if you've got real guts and can do the due diligence and required research, exchange your ETH for a newly issued token and gamble on an ICO. Wait until sentiment has reached the complete loss of faith in ETH, and it is given up for dead. That is when like a phoenix, it will arise from the ashes.
