Robinhood Stock
Robinhood stock has surged 266.9% in 2025 as of Sept. 29. Shares broke out past a double-bottom base with a 51.30 handle buy point on May 8, more than doubling over the next three months. The online free trading app then pulled back, briefly undercutting the 50-day line in early September. HOOD stock then gapped up on Sept. 8 on the news that it would join the S&P 500 index. Robinhood hit a record 130.07 on Sept. 24 before pulling back slightly to end the week.
HOOD stock jumped 12.3% Monday, adding to the year's hefty gain.
Seagate Leads S&P 500 Stock Memory Plays
Seagate stock has soared 165.5%, as the AI boom has lifted memory plays, including Western Digital and Micron Technology. STX stock broke out of a long consolidation on May 27, though savvy investors might have started a position as it gapped above the 200-day line about two weeks earlier.
Since then, Seagate has been hard to enter. A quick 10-week line test in late July and clearing a range a few weeks later offered brief windows that paid off with a big run just in the past five weeks.
Seagate stock popped 5.35% Monday.
