Both timeframes are pointing down with lower highs stacking up, and the 4H RSI is already oversold — so this is momentum still pushing, not a fresh turn.
SKHYNIX is already down over 16% today with both timeframes pointing down and a strong trend behind the move, so I'm riding the downside while it keeps printing lower highs.
SNDK is already down almost 11% today and just broke below its lower Bollinger band, so the downside still has room to run while both timeframes point down.
