Sutro Biopharma Stock Forecast

Buy candidate since Jun 26, 2026

The Sutro Biopharma Inc. stock price gained 3.28% on the last trading day (Friday, 26th Jun 2026), rising from $29.55 to $30.52. During the last trading day the stock fluctuated 8.38% from a day low at $28.75 to a day high of $31.16. The price has risen in 7 of the last 10 days and is up by 15.26% over the past 2 weeks. Volume has increased on the last day along with the price, which is a positive technical sign, and, in total, 2 million more shares were traded than the day before. In total, 3 million shares were bought and sold for approximately $84.65 million.

The stock is moving within a very wide and horizontal trend and further movements within this trend can be expected. Given the current horizontal trend, you can expect Sutro Biopharma Inc. stock with a 90% probability to be traded between $24.58 and $41.17 at the end of this 3-month period. A break of a horizontal trend is often followed by a large increase in the volume, and stocks seldom manage to go directly from the bottom of a trend up to the top. Stocks turning up in the middle of a horizontal trend are therefore considered to be potential runners.

STRO Signals & Forecast

A buy signal was issued from a pivot bottom point on Tuesday, June 02, 2026, and so far it has risen 24.93%. 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). Volume is rising along with the price. This is considered to be a good technical signal. Some negative signals were issued as well, and these may have some influence on the near short-term development. The Sutro Biopharma Inc. stock holds a buy signal from the short-term Moving Average; at the same time, however, the long-term average holds a general sell signal. Since the longterm average is above the short-term average there is a general sell signal in the stock giving a more negative forecast for the stock. On further gains, the stock will meet resistance from the long-term Moving Average at $30.89. On a fall, the stock will find some support from the short-term average at $29.84. A break-up through the long-term average will give another buy signal, while a fall below the short-term average will add another sell signal and strengthen the general signal.

Support, Risk & Stop-loss for Sutro Biopharma Inc. stock

On the downside, the stock finds support just below today's level from accumulated volume at $28.78 and $27.38. 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, Sutro Biopharma Inc. finds support just below today's level at $28.78. If this is broken, then the next support from accumulated volume will be at $27.38 and $25.57.

This stock may move much during the day (volatility) and with a large prediction interval from the Bollinger Band this stock is considered to be "high risk". During the last day, the stock moved $2.41 between high and low, or 8.38%. For the last week, the stock has had daily average volatility of 9.18%.

Our recommended stop-loss: $29.23 (-4.22%) (This stock has high daily movements and this gives high risk. There is a buy signal from a pivot bottom found 17 days ago.)

Trading Expectations (STRO) For The Upcoming Trading Day Of Monday 29th

For the upcoming trading day on Monday, 29th we expect Sutro Biopharma Inc. to open at $30.14, and during the day (based on 14 day Average True Range), to move between $29.10 and $31.94, which gives a possible trading interval of +/-$2.84 (+/-9.74%) up or down from last closing price. If Sutro Biopharma Inc. takes out the full calculated possible swing range there will be an estimated 9.74% move between the lowest and the highest trading price during the day.

Since the stock is closer to the resistance from accumulated volume at $31.55 (3.37%) than the support at $28.78 (5.70%), 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.
