Spero Therapeutics Stock Forecast

Sell candidate since Jun 17, 2026 Loss -0.47%

The Spero Therapeutics Inc. stock price fell by -0.94% on the last day (Friday, 10th Jul 2026) from $2.12 to $2.10. During the last trading day the stock fluctuated 4.15% from a day low at $2.05 to a day high of $2.14. The price has fallen in 6 of the last 10 days but is still up by 3.96% over the past 2 weeks. Volume has increased on the last day by 121 thousand shares but on falling prices. This may be an early warning and the risk will be increased slightly over the next couple of days. In total, 481 thousand shares were bought and sold for approximately $1.01 million.

The stock lies in the lower of a very wide and falling trend in the short term, and this may normally pose a very good buying opportunity. If the lower trend floor at $1.93 is broken, it will firstly indicate a stronger fall rate. Given the current short-term trend, the stock is expected to fall -16.10% during the next 3 months and, with a 90% probability hold a price between $1.62 and $2.32 at the end of this 3-month period.

SPRO Signals & Forecast

A buy signal was issued from a pivot bottom point on Thursday, June 25, 2026, and so far it has risen 3.96%. Further rise is indicated until a new top pivot has been found. 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. The Spero Therapeutics Inc. stock holds sell signals from both short and long-term Moving Averages giving a more negative forecast for the stock. Also, there is a general sell signal from the relation between the two signals where the long-term average is above the short-term average. On corrections up, there will be some resistance from the lines at $2.17 and $2.51. A break-up above any of these levels will issue buy signals. Spero Therapeutics Inc. gained volume on the last day, but on falling prices. In technical terms, this is called divergence and may be an early warning. In some cases, increasing volume on falling prices may be considered positive, but that is mainly in typical "sell-offs".

Trading Expectations (SPRO) For The Upcoming Trading Day Of Monday 13th

For the upcoming trading day on Monday, 13th we expect Spero Therapeutics Inc. to open at $2.10, and during the day (based on 14 day Average True Range), to move between $2.02 and $2.18, which gives a possible trading interval of +/-$0.155 (+/-7.68%) up or down from last closing price. If Spero Therapeutics Inc. takes out the full calculated possible swing range there will be an estimated 7.68% move between the lowest and the highest trading price during the day.

Since the stock is closer to the resistance from accumulated volume at $2.11 (0.48%) than the support at $2.02 (3.81%), 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.
