RIVN Dives 6.3% Amid Volatile Intraday Action — Is This the Start of a Larger Move?

Summary
• Rivian Automotive (RIVN) plunges over 6% in a single day, breaking key support levels.
• Intraday price swing from $16.05 to $14.97 shows deep market uncertainty.
• Options chain reveals sharp increase in activity around $14 and $15 strike prices.

Rivian Automotive is currently trading at $15.11, down nearly 6.3% from the previous close, amid heavy turnover and a mixed technical landscape. The stock’s sharp selloff and heavy options trading point to growing bearish sentiment. With Tesla (TSLA) also down in the sector, the broader EV market is showing signs of weakness. This article breaks down the forces behind the move and what options traders are doing.

Profit-Taking and Technical Deterioration Ignite Sell-Off
The sharp drop in RIVN today is driven by a combination of profit-taking and deteriorating technical indicators. After opening near $16, the stock quickly gave up early gains and fell into a bearish bias. The RSI at 56.64 and a negative MACD histogram signal that momentum is shifting to the downside. With the stock trading below the 30-day moving average and near its lower Bollinger Band, the move is likely a result of short-term bearish traders stepping in and long-term investors re-evaluating their positions. The negative sentiment is also reflected in the increased activity in put options around key support levels.

Automotive Sector Weighed Down by Broader Selloff — Tesla Leads the Fall
The broader automotive sector is showing weakness today with Tesla (TSLA) down 2.1%, indicating a broader sell-off rather than a standalone RIVN event. While Rivian’s drop is steeper than the sector average, it mirrors the general decline in investor confidence. This suggests that the move is more macroeconomic than company-specific at this point. Investors should watch how Tesla responds, as it may serve as a barometer for the sector's next move.

Bearish Options and ETFs Take Center Stage as RIVN Breaks Key Levels
• 200-day MA: 14.95 (near, bearish signal)
• 30-day MA: 15.40 (broken to the downside)
• RSI: 56.64 (neutral but trending lower)

• Bollinger Bands: 16.47 (upper), 15.46 (middle), 14.44 (lower) (near lower band)

With RIVN breaking through key technical support levels and trading near its lower Bollinger Band, a bearish bias appears to be in place. The stock is now trading in the vicinity of its 200-day moving average, which could either hold or be broken to trigger further downside. The options chain reveals a high volume of activity around the $14 and $15 strike prices, particularly in the March 27 put and call options. Below are two top options with favorable characteristics for a near-term bearish trade:

For RIVN20260327P13.5, the payoff would be $0.85 (max(0, 13.5 - 14.35) = 0.85). These payoffs indicate that both options are strong bearish plays in a near-term downtrend.

Backtest Rivian Automotive Stock Performance
The backtest of Rivian Automotive (RIVN) after an intraday plunge of -6% from 2022 to the present shows mixed short-term performance but a slight positive return over the longest 30-day period. The 3-Day win rate is 46.28%, the 10-Day win rate is 45.55%, and the 30-Day win rate is also 45.55%. The average returns over these periods are slightly negative, with a -0.26% return over 3 days, a -0.91% return over 10 days, and a -0.69% return over 30 days.

Time to Watch the $14.44 Level — A Break Below Could Signal a Larger Move
RIVN is now at a critical juncture with its price near the 200-day moving average and the lower Bollinger Band. A break below $14.44 could confirm a more significant bearish move and invite further short sellers and put option buyers into the fray. The options activity and technical indicators suggest that the bearish trend is gaining strength. With Tesla also in the red, the sector-wide weakness supports a cautious outlook. Traders should closely watch for a breakdown below $14.44 and a sustained move below the 200-day MA as confirmation of a larger trend. Given Tesla’s 2.1% decline, investors may want to assess whether the broader EV sector is a factor in this move. If RIVN closes below $14.44, it could become a high-conviction short setup for the week ahead.
