BLGO Signals & Forecast

A buy signal was issued from a pivot bottom point on Friday, October 31, 2025, and so far it has risen 0.153%. Further rise is indicated until a new top pivot has been found. BioLargo, Inc has increased volume and follows the last lift in the price. This is considered to be a technical positive sign as volume should follow the price-formation. The very low volume increases the risk and reduces the other technical signals issued. Some negative signals were issued as well, and these may have some influence on the near short-term development. The BioLargo, Inc stock holds sell signals from both short and long-term Moving Averages giving a more negative forecast for the stock. On corrections up, there will be some resistance from the lines at $0.168 and $0.166. A break-up above any of these levels will issue buy signals. Furthermore, there is currently a sell signal from the 3 month Moving Average Convergence Divergence (MACD).
