Horizon

Medium

Invalidation

Thesis weakens if catalysts slip or risk markers breach stated levels.

Bias

OVERWEIGHT

Catalysts

  • Short-term trend is bearish. Price is below the 50-day SMA, RSI is sub-50, and MACD is negative and still deteriorating.
  • Long-term trend remains positive (price above 200-day SMA, golden cross intact), but that support is getting tested.
  • The $955–$965 zone is critical. The 200-day SMA (~$955) and the June 4–5 lows (~$968–$972) represent the next major support. A break below $936 (June 1 low) would put the 200-day SMA at risk.

Risks

  • Event-driven repricing risk if expectations diverge from incoming evidence.
