GWH is trading below its 200-day MA ($1.44) — a key warning sign the longer-term trend is under pressure. An RSI of 28.9 has dropped into oversold territory, which has historically preceded short-term bounces. The 1-year return of -73.7% compares to +20.5% for SPY (trailed the market by 94.2%). The current 97.1% drawdown from the 52-week high reflects elevated risk for momentum-based strategies.
