$SES SES AI Corporation exploded higher in the closing hour, surging +17.43% to $2.06 on massive volume. The stock traded 23.08 million shares against a 8.98 million average, representing a 157% volume spike that screams institutional involvement. While technical indicators show the RSI entering overbought territory, the magnitude of the move suggests more than just retail enthusiasm. The company's AI-powered battery technology continues to attract attention from institutional players, though traders should note the overbought conditions may lead to near-term consolidation. This appears to be genuine accumulation rather than FOMO, given the sustained volume throughout the power hour.

$BTU Peabody Energy Corporation surged +9.31% to $32.03 with 9.65 million shares changing hands nearly double the 4.99 million daily average. This 93% volume spike in a coal and energy producer suggests institutional money rotating into commodities and traditional energy plays. The coal sector has been quietly building momentum, and today's power hour buying indicates smart money may be positioning ahead of seasonal demand increases. The sustained buying pressure into the close, rather than profit-taking, signals conviction behind this move.

$NPWR NET Power Inc. posted an impressive +8.83% gain to $3.39, trading 2.01 million shares versus its 932,580 average a remarkable 115% volume increase. This clean energy technology company is seeing legitimate institutional interest, with the late-day spike suggesting accumulation rather than speculative retail trading. The volume pattern indicates buyers stepped in aggressively during the final hour, absorbing any profit-taking from earlier gains.

$BANC Banc of California gained +0.74% to $17.05, but the story here is the volume: 4.25 million shares traded against a 2.26 million average, marking an 88% volume surge. While the price move appears modest, this type of accumulation pattern in regional banking stocks often precedes larger moves. Financial institutions typically trade on lower volatility, making this volume anomaly particularly noteworthy. Smart money may be quietly building positions ahead of quarterly earnings or sector rotation.

$XPON Expion360 Inc. rallied +9.15% to $1.67, though interestingly on 1.91 million shares versus a 2.68 million average. This represents 29% below normal volume, suggesting the move was driven by a smaller pool of determined buyers rather than broad institutional accumulation. This pattern often indicates either insider knowledge or concentrated buying from a specific fund. Traders should approach with caution low-volume spikes can reverse quickly without sustained interest.

$GRAIL GRAIL Inc. climbed +1.56% to $65.74, marking its seventh consecutive daily gain a winning streak that's caught the attention of momentum traders. Volume came in at 1.75 million shares versus an 828,100 average, representing a 111% spike. Seven-day winning streaks are statistically rare and often attract algorithmic momentum strategies during the power hour. The consistent volume expansion suggests institutional participation rather than pure retail FOMO, though traders should watch for exhaustion signals after such an extended run.
