WTI crude dipped below $50 per barrel on Monday, the first time oil dipped below that level in more than a year. Oil prices are now in bear market territory compared to their previous 52-week highs, and WTI crude has dropped 20% over the past month. Even with an early bump in oil on Tuesday crude settled lower for the day, and don't expect the bearish trend in the commodity to reverse itself soon, according to trading history over the past decade.

According to hedge fund analytics tool Kensho, a month after similar drops, WTI crude tends to shed another 10%. It trades negatively 60% of the time during these periods — across five instances in the past decade — which also have been hard on equities. The S&P 500 has averaged a decline of 1.6% during these one-month trading windows and posts a negative trade 60% of the time.

The trading action in WTI crude and Brent crude through Monday has been rough, as fears of the coronavirus ripple through the global economy, and China, which now represents near-20% of the world's economy, is at risk of seeing slower growth.

Brent had its lowest settle price since December 2018 on Monday and is in bear market territory, 27.98% off its most recent 52-week high, from April 2019. It has been below its 50-day moving average for 10 days in a row.
