Mersana Therapeutics Stock Forecast

Buy candidate since Nov 14, 2025 Loss -0.72%

The Mersana Therapeutics, Inc. stock price fell by -0.716% on the last day (Monday, 17th Nov 2025) from $27.92 to $27.72. During the last trading day the stock fluctuated 1.84% from a day low at $27.54 to a day high of $28.05. The price has risen in 6 of the last 10 days and is up by 193.64% over the past 2 weeks. Volume fell on the last day along with the stock, which is actually a good sign as volume should follow the stock. On the last day, the trading volume fell by -267 thousand shares and in total, 148 thousand shares were bought and sold for approximately $4.10 million.

The stock lies in the upper part of a very wide and strong rising trend in the short term, and this may normally pose a very good selling opportunity for the short-term trader as reaction back towards the lower part of the trend can be expected. A break-up at the top trend line at $28.04 will firstly indicate a stronger rate of rising. Given the current short-term trend, the stock is expected to rise 36.83% during the next 3 months and, with a 90% probability hold a price between $12.13 and $38.36 at the end of this 3-month period.

MRSN Signals & Forecast

The Mersana Therapeutics, Inc. 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 $16.84 and $10.79. 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, November 14, 2025, and so far it has fallen -0.716%. 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 Mersana Therapeutics, Inc. stock

Mersana Therapeutics, Inc. finds support from accumulated volume at $27.43 and this level may hold a buying opportunity as an upwards reaction can be expected when the support is being tested.

This stock may move very much during the day (volatility) and with a very large prediction interval from the Bollinger Band this stock is considered to be "very high risk". During the last day, the stock moved $0.507 between high and low, or 1.84%. For the last week, the stock has had daily average volatility of 4.61%.

The Mersana Therapeutics, Inc. stock is overbought on RSI14 and lies in the upper part of the trend. Normally this may pose a good selling opportunity for the short-term trader, but some stock may go long and hard while being overbought. Regardless, the high RSI together with the trend position increases the risk and higher daily movements (volatility) should be expected. A correction down in the nearby future seems very likely and it is of great importance that the stock manages to break the trend before that occurs.

Our recommended stop-loss: $26.74 (-3.53%) (This stock has very high daily movements and this gives very high risk. The RSI14 is 87 and this increases the risk substantially. There is a sell signal from a pivot top found 1 day ago.)

Trading Expectations (MRSN) For The Upcoming Trading Day Of Tuesday 18th

For the upcoming trading day on Tuesday, 18th we expect Mersana Therapeutics, Inc. to open at $27.77, and during the day (based on 14 day Average True Range), to move between $26.81 and $28.63, which gives a possible trading interval of +/-$1.81 (+/-6.76%) up or down from last closing price. If Mersana Therapeutics, Inc. takes out the full calculated possible swing range there will be an estimated 6.76% move between the lowest and the highest trading price during the day.

Since the stock is closer to the resistance from accumulated volume at $27.92 (0.72%) than the support at $27.43 (1.05%), 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.

Due to some small weaknesses in the technical picture we have downgraded our analysis conclusion for this stock since the last evaluation from a Strong Buy to a Buy candidate.
