Premarket Movers Nov 4, 2026: Why FTCI, RIOT, ARRY Are Up

FTCI — FTC Solar, Inc. (+24.1%)

FTC Solar is up 24.1% to $1.80 in premarket trading, the biggest move on this morning's list. About 28.8 million shares have traded, against a 20-day average of just 213,311 for a full day. Premarket volume is lighter than regular hours, so that is an extreme surge in activity. The market cap is only about $23.9 million, which makes this a micro-cap.

The catalyst is third-quarter earnings. FTC Solar reported revenue of $32.8 million, up 25.4% from the second quarter, and guided fourth-quarter revenue to $44 million to $52 million. The picture is not clean. The adjusted net loss was $7.6 million. The company ended the quarter with $5.1 million of cash and a stockholders' deficit of $17.4 million. Headlines also point to a credit deal that extends its runway.

The setup it carried in was weak. The stock is 88.6% below its 52-week high, with a bearish moving-average stack, RSI of 36, a relative strength rating of 5 and a conviction score of 32/100 (grade D). No chart pattern signal was active. Short-volume is 64% of recent volume, and free float is 68.5%. Short-volume is the share of trading that was short selling. It is not the same as total short interest.

Insiders bought in August. Director-level buyer Shaker Sadasivam bought 39,583 shares ($93K) on Aug. 27 and 33,290 shares ($73K) on Aug. 26. CEO Anthony Carroll bought 24,745 shares ($51K) on Aug. 25. Those are small purchases. Thin liquidity and a tight balance sheet make this a very risky name.

RIOT — Riot Platforms, Inc. (+13.1%)

Riot Platforms is up 13.1% to $15.85 in premarket trading on 16.4 million shares. That is already close to its 20-day average daily volume of 19.3 million, with the regular session still ahead. The market cap is about $5.3 billion.

The driver is Q3 results plus a large lease. Riot reported revenue of $181.4 million, up 1% from a year earlier, and mined 1,637 bitcoin. It also announced a 15-year lease of 910 MW of capacity at its Corsicana campus to an unnamed frontier AI lab, worth about $28 billion in total rent. Riot says it does not currently expect to issue equity for these projects and plans to fund them with project debt. Headlines show the reaction is mixed. One cites a 20% surge and another a slide as investors reset crypto-AI expectations, so the premarket gain may move around.

The prior-day chart was not strong. RIOT showed a bullish marubozu, a candle with a long body and almost no wicks. But the moving-average stack was bearish, RSI was 43, and the stock sat 53.8% below its 52-wk high. ADX of 38 signals a strong trend, which in this case was a downtrend. Its relative strength rating is 16, conviction is 36/100 (grade D) and the trend-template score is 1. Short-volume is 57%, free float is 92.8%, and the largest disclosed stake is 7.6%. Reddit chatter is minimal.

NVTS — Navitas Semiconductor Corp (+10.0%)

Navitas is up 10.0% to $9.44 in premarket trading on about 3.1 million shares, against a 20-day average of 14.3 million. Its market cap is about $1.6 billion.

The catalyst is earnings after the Nov. 3 close. Navitas reported third-quarter revenue of $14.0 million, up 33% from the prior quarter and 38% from a year earlier. It guided fourth-quarter revenue to $16.0 million and said AI data center and energy infrastructure should exceed 40% of sales by year-end. It still posted a GAAP net loss of $37.1 million. Headlines also mention a Craig Hallum upgrade.

Going in, the daily setup was soft. The stock is 74.9% below its 52-wk high, the moving-average stack was bearish, RSI was 40 and ADX was 24, which shows a modest trend. No pattern signal was active. Relative strength is 23, conviction is 32/100 (grade D) and the trend-template score is 2. Short-volume is 39% and free float is 83.3%. Reddit mentions rose to 3 from 1 a day earlier, which is still small.

ARRY — Array Technologies, Inc. (+12.7%)

Array Technologies is up 12.7% to $5.24 in premarket trading on about 4.3 million shares, against a 20-day average of 8.4 million. Market cap is about $716 million.

This is a merger story. Array and Shoals agreed to a stock-for-stock deal in which each Shoals share converts into 1.6931 Array shares. Shoals holders would own about 65% of the combined company and Array holders about 35%. Shoals' CEO would lead it, and the companies target more than $100 million of annual synergies within three years. The deal needs both shareholder votes and is expected to close in the first quarter of 2027. Array also missed Q3 earnings estimates, according to a Yahoo Finance headline. Deals can fall through or change before closing.

The prior-day chart showed a bullish marubozu, RSI of 68, ADX of 38 and a mixed moving-average stack. The stock is still 62.0% below its 52-wk high. Relative strength is 15, conviction is only 4/100 (grade D) and the trend-template score is 2. The smart-money score is 18/100, with a largest disclosed stake of 12.0%. Short-volume is 62% and free float is 99.3%.

The bottom line

Three of these four moves come from earnings and one from a merger. Each stock is also well below its 52-week high and carried a weak technical score into the morning. Premarket prices are thin and can reverse quickly at the open. Chasing extended gainers is high-risk, and patterns and squeezes fail often. Size positions carefully, use defined stops and do your own research. This is educational content, not financial advice.
