The SEC Just Opened The Floodgates… (Ad)

The SEC removed the 25 year old Pattern Day Trader rule in June 2026, cutting the minimum to open a trading account to just 2,000 dollars. Small cap stocks like ONFO, CURR, RMSG, TMDE and VSME have already posted gains ranging from 140 percent to 482 percent, some in a single day. Tim Bohen, known for flagging Tesla at 37 and Nvidia at 6.93, believes this shift could trigger the next major small cap breakout.tc pixel
