Latest Activity
A 5.95% intraday run to $13.53 adds better than a billion dollars to a roughly $20 billion market cap in one session. Moves this size rarely stay quiet in this name, so keep an eye on whether it holds into the close.
IDEXX Laboratories opened 16.33% higher, the largest single move across a 380-stock priority universe today. Lumentum anchors the other end, with Oracle and Marvell also lower.
Rivian now has someone new signing off on the numbers, and the Form 3 confirms the finance seat changed hands at a $17.6 billion EV maker still scaling its Amazon van business. Interim CFO transitions tend to reset how guidance gets framed, so the next earnings call is the one to listen to closely.
Automotive cost per unit improved by more than $12,000 quarter over quarter, the clearest sign yet that the R2, now Rivian's best-selling vehicle, can bend the loss curve. Cash burn is still real, but this is the first quarter the ramp paid for itself.
Rivian just marked a new 52-week low at $11.43, 3.38% below the low it set only three sessions earlier. The EV maker's market cap is down to $16.5 billion, with each bounce this year topping out lower than the last.
Rivian just undercut its November 2025 floor, closing at $12.42, 0.64% below the prior 52-week low. The EV maker's market cap is down to $17.9 billion with the stock now at the bottom of its yearlong range.
A 5.21% slide to $12.47 knocks roughly $1 billion off Rivian's $18 billion market cap in a single session. Moves this size on no company-specific news tend to set the near-term trading range, so keep an eye on the stock.
A 6.6% slide to $14.24 takes roughly $1.4 billion off a $20.6 billion market cap in a single session. Moves this size leave the EV maker's valuation resting on whether the $14 area holds into the close.
A 7.6% intraday slide to $14.08 takes roughly $1.7 billion off a $20 billion market cap in a single session. Moves this size in the EV startup cohort rarely stay quiet, so keep an eye on the stock through the close.
