Yen at 40-year low with intervention looming — hedge US stock exposure
Thesis
The Yen is at its weakest level since 1986, and MarketWatch reports Japan may specifically target low-liquility U.S. holiday periods to intervene. This sets up a binary event: if Japan acts, the Yen spikes violently, which historically forces global investors to unwind risk and can trigger sudden selloffs in U.S. equities just as they celebrate their best quarter in six years. This trade prepares for the shock by positioning for a sudden flight-to-safety event or hedging long stock portfolios.
Strategy approach
Build a defensive short-term strategy for EWJ (Japan ETF) on the H4 (4-hour) timeframe. Enter long when the Yen strengthens sharply (EWJ drops) — specifically when the 14-period RSI on USDJPY drops below 25 (extreme oversold) signaling sudden Yen strength. Exit the position within 48 hours or when USDJPY bounces back above its 20-period moving average. Set a tight 3% stop loss.
