Rivian rallied 11.6% this week to $14.39 — a sharp reversal from last week's fresh lows — yet the bears who built positions through April and early May have barely flinched.
Short interest moved in the opposite direction of the price. At 12.2% of the free float, SI edged up another 0.6% over the past five sessions and is now 6.6% higher than a month ago. That persistence is the story: shorts are not covering into the bounce. The most recent FINRA filing puts days-to-cover at 4.6, and the ORTEX short score ticked up to 71.6 — a fresh recent high and well above where it started the month. Bears have conviction here.
The lending market gives shorts no reason to rush for the exit. Availability is running at 106%, meaning the pool of shares available to borrow still exceeds outstanding short positions. Borrow costs edged up 14% on the week but remain negligible at 0.51% APR — near the cheapest levels of the past year. There is no squeeze pressure in the lending dynamics. That said, the availability reading has tightened noticeably from April levels, when it was above 160%, and is now holding close to its 52-week low of 68.8%. Shorts can still get on, but the pool is measurably smaller than it was six weeks ago.
Options positioning has shifted. The put/call ratio dropped to 0.85, now slightly below its 20-day average of 0.88 and close to its 52-week low of 0.78. That is a notable rotation from late April, when the PCR was running above 1.0 and options traders were hedging heavily. The rally appears to have drawn in call buyers. The z-score of -0.74 is not extreme, but the direction of travel — from defensive to incrementally bullish — is a meaningful contrast with what the short interest data says.
The Street is cautiously leaning positive. The mean analyst price target of ~$18 implies roughly 26% upside from current levels. Recent analyst moves are a mixed bag: BNP Paribas trimmed its target from $23 to $22 while holding Outperform after last month's print, and DA Davidson nudged its target up to $15 while staying Neutral. Bulls at Needham and Benchmark are holding $23–$25 targets unchanged. The factor scores are a drag — EPS momentum ranks in the 17th percentile over 30 days and the short score percentile ranks in the bottom 5% of the universe. The Volkswagen partnership remains the cornerstone of the bull case, with VW holding 16.4% of shares and having added 62.9 million shares in the most recent reported period. Amazon sits at 12.4%, unchanged.
On the insider side, the CFO sold roughly $180,000 worth of stock across two transactions this week at prices between $13.43 and $14.00. CEO Robert Scaringe also sold ~$640,000 at $14.52 on May 15, alongside awards vesting for several senior executives. These are routine-looking transactions tied to compensation cycles, not a signal on their own. The 90-day net insider position is heavily distorted by equity awards, making the headline figure of $1 billion net less meaningful than it appears.
Earnings are next on June 22. The last print on April 30 saw the stock drop 6.5% the following day and 11.7% over the subsequent five sessions. The one before that, in early May, produced a negligible 1-day move. Tesla gained 5.8% this week, and Ford surged 17.6% — the auto sector broadly caught a bid. Whether Rivian's bounce can consolidate into the June 22 earnings release, or whether short sellers use the reprieve to reload at higher prices, is the central question heading into next month.
