SPTX Signals & Forecast

The Seaport Therapeutics, Inc. Common Stock stock holds buy signals from both short and long-term Moving Averages giving a positive forecast for the stock. Also, there is a general buy signal from the relation between the two signals where the short-term average is above the long-term average. On corrections down, there will be some support from the lines at $22.09 and $20.76. A breakdown below any of these levels will issue sell signals. Furthermore, there is a buy signal from the 3 month Moving Average Convergence Divergence (MACD). Some negative signals were issued as well, and these may have some influence on the near short-term development. A sell signal was issued from a pivot top point on Friday, August 07, 2026, and so far it has fallen -2.54%. Further fall is indicated until a new bottom pivot has been found. Volume fell together with the price during the last trading day and this reduces the overall risk as volume should follow the price movements.

Support, Risk & Stop-loss for Seaport Therapeutics, Inc. Common Stock stock

On the downside, the stock finds support just below today's level from accumulated volume at $18.97 and $18.17. There is a natural risk involved when a stock is testing a support level, since if this is broken, the stock then may fall to the next support level. In this case, Seaport Therapeutics, Inc. Common Stock finds support just below today's level at $18.97. If this is broken, then the next support from accumulated volume will be at $18.17 and $17.99.

This stock has average movements during the day and with good trading volume, the risk is considered to be medium. During the last day, the stock moved $1.40 between high and low, or 6.14%. For the last week, the stock has had daily average volatility of 6.07%.

Our recommended stop-loss: $21.94 (-4.71%) (This stock has medium daily movements and this gives medium risk. There is a sell signal from a pivot top found 1 day ago.)

Trading Expectations (SPTX) For The Upcoming Trading Day Of Tuesday 11th

For the upcoming trading day on Tuesday, 11th we expect Seaport Therapeutics, Inc. Common Stock to open at $23.34, and during the day (based on 14 day Average True Range), to move between $22.28 and $23.76, which gives a possible trading interval of +/-$1.48 (+/-6.62%) up or down from last closing price. If Seaport Therapeutics, Inc. Common Stock takes out the full calculated possible swing range there will be an estimated 6.62% move between the lowest and the highest trading price during the day.

Since the stock is closer to the resistance from accumulated volume at $23.09 (0.30%) than the support at $18.97 (17.59%), our systems don't find the trading risk/reward intra-day attractive and any bets should be held until the stock is closer to the support level.
