Rivian Automotive shares are climbing with conviction. Why are RIVN shares rallying?

The latest push higher follows upbeat EV commentary from British motoring journalist James May, who said he’d pick Rivian’s R1T over Tesla’s Cybertruck, calling out the R1T’s interior styling, overall design "mood," and its "gear tunnel" storage feature. He also noted the R1T would hold "roughly half as much" luggage as the Cybertruck, and that the reviewed vehicle was supplied by Rivian rather than purchased.Rivian CEO RJ Scaringe also recently argued Americans aren’t “anti-EV” but simply lack options, noting Tesla’s Model 3 and Y comprise roughly 50% of U.S. EV sales. To compete, Rivian this month launched deliveries of its highly anticipated R2 SUV; its Performance model starts at $57,990, slightly undercutting a comparable Model Y ($58,880).Rivian will expand the R2 lineup with Premium ($53,990) and standard ($48,490) versions in 2026 and 2027. The company projects 62,000 to 67,000 total deliveries for 2026, aiming for an annual production capacity of 300,000 units by 2028.RIVN: Key Technical Levels To WatchRivian is trading above its key moving averages, which keeps the longer-term repair intact: it’s about 3.3% above the 20-day SMA ($16.19) and roughly 6%–8% above the 50-, 100-, and 200-day SMAs ($15.56, $15.48, and $15.73). That said, the "death cross" from May (50-day SMA below the 200-day SMA) is still a longer-term headwind until the 50-day can reclaim the 200-day and hold.For momentum, MACD is the cleaner read right now: it’s below its signal line with a negative histogram, which suggests upside pressure is cooling versus the prior upswing unless buyers can re-accelerate. RSI is no longer in the "stretched" zone after June’s overbought signal, which fits the idea that the stock may need consolidation even after sharp up-days.
