BLDR is trading below its 200-day MA ($115.39) — a key warning sign the longer-term trend is under pressure. An RSI of 62.8 sits in the neutral zone — momentum is neither stretched nor exhausted. The 1-year return of -21.7% compares to +35.1% for SPY (trailed the market by 56.8%). The current 41.4% drawdown from the 52-week high reflects elevated risk for momentum-based strategies.
