The VanEck Oil Services ETF (OIH) has more than doubled over the past year, but the underlying positioning tells a different story. Short interest has collapsed over the same period, leaving the rally increasingly dependent on incremental long demand, just as momentum signals begin to diverge.

Short Interest / Positioning

Short interest has fallen by -73% over the past 1Y, declining from 3.0M shares (70% outstanding) to less than 0.8M (15%), currently sitting at historical lows.

Over the same period, OIH price performance is up >100%, confirming the move has been partially driven by shorts unwinding bearish positioning into the strength.

The setup has transitioned to a positioning vacuum, where limited remaining short exposure reduces further buy-to-cover upside.

Technicals

OIH remains in a well-defined uptrend, trading above its rising 50-day moving average ($398).

However, RSI (>72, overbought) and MACD are showing negative divergence (lower highs, red arrows), with both momentum indicators failing to confirm the higher highs in the stock price.

Trading Volume has also been trending lower into the rally (orange arrow), reinforcing signs of waning participation, and late-stage trend behavior.

Next Move

OIH has become increasingly reliant on momentum, with short interest now at historical lows. As momentum begins to diverge, the setup creates an opportunity for short sellers to re-engage into strength.

The setup is no longer about covering - it’s about reloading.
