Sell candidate since Oct 09, 2025 Loss -36.02%

The Zai Lab Ltd stock price fell by -3.82% on the last day (Monday, 17th Nov 2025) from $21.75 to $20.92. During the last trading day the stock fluctuated 3.62% from a day low at $20.60 to a day high of $21.35. The price has fallen in 8 of the last 10 days and is down by -21.79% for this period. 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 -29 thousand shares and in total, 466 thousand shares were bought and sold for approximately $9.76 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 $19.53 is broken, it will firstly indicate a stronger fall rate. Given the current short-term trend, the stock is expected to fall -29.43% during the next 3 months and, with a 90% probability hold a price between $13.78 and $20.00 at the end of this 3-month period. Do note, that if the stock price manages to stay at current levels or higher, our prediction target will start to change positively over the next few days as the conditions for the current predictions will be broken.

ZLAB Signals & Forecast

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 Zai Lab Ltd 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 $21.72 and $27.67. A break-up above any of these levels will issue buy signals. A sell signal was issued from a pivot top point on Wednesday, October 01, 2025, and so far it has fallen -39.26%. 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 Zai Lab Ltd stock

There is no support from accumulated volume below today's level and given the right condition the stock may perform very badly in the next couple of days.

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 $0.745 between high and low, or 3.62%. For the last week, the stock has had daily average volatility of 2.80%.

Zai Lab Ltd is oversold on RSI14 (20). Some stock may drop long and hard while being oversold on RSI before turning, which increases the general risk.

Our recommended stop-loss: We hold a negative evaluation for this stock. No stop-loss is set.

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

For the upcoming trading day on Tuesday, 18th we expect Zai Lab Ltd to open at $20.96, and during the day (based on 14 day Average True Range), to move between $20.36 and $21.48, which gives a possible trading interval of +/-$1.12 (+/-5.50%) up or down from last closing price. If Zai Lab Ltd takes out the full calculated possible swing range there will be an estimated 5.50% move between the lowest and the highest trading price during the day.

With no support below and resistance from accumulated volume @ $21.89, some $0.97 (4.64%) from the current price of $20.92, our system finds the risk reward not very attractive.

Is Zai Lab Ltd stock A Buy?

Zai Lab Ltd holds several negative signals and is within a very wide and falling trend, so we believe it will still perform weakly in the next couple of days or weeks. We therefore hold a negative evaluation of this stock.
