Oasis Petroleum was one of the hardest hit producers following the collapse of oil. As oil begins to recover and OPEC+ agree on productions cuts, we will see OAS begin to climb back.
As the RSI chart indicates, the price has oscillated in a tight range. However, the RSI has begun to diverge and move upward indicating a bullish bias. The stock as at all times lows. Oil is not going away any time soon. Safe to accumulate long positions here in my opinion.
