RLYB Signals & Forecast

The Rallybio Corporation stock holds a sell signal from the short-term Moving Average; at the same time, however, there is a buy signal from the long-term average. Since the short-term average is above the long-term average there is a general buy signal in the stock giving a positive forecast for the stock. On further gains, the stock will meet resistance from the short-term Moving Average at approximately $0.656. On a fall, the stock will find some support from the long-term average at approximately $0.595. A break-up through the short-term average will send a buy signal, whereas a breakdown through the long-term average will send a sell signal. 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 Tuesday, November 11, 2025, and so far it has fallen -12.47%. Further fall is indicated until a new bottom pivot has been found. Furthermore, there is currently a sell signal from the 3 month Moving Average Convergence Divergence (MACD). Rallybio Corporation 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".

Support, Risk & Stop-loss for Rallybio Corporation stock

On the downside, the stock finds support just below today's level from accumulated volume at $0.578 and $0.565. 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, Rallybio Corporation finds support just below today's level at $0.578. If this is broken, then the next support from accumulated volume will be at $0.565 and $0.499.

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 $0.0669 between high and low, or 11.30%. For the last week, the stock has had daily average volatility of 9.49%.

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

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

For the upcoming trading day on Tuesday, 18th we expect Rallybio Corporation to open at $0.623, and during the day (based on 14 day Average True Range), to move between $0.592 and $0.642, which gives a possible trading interval of +/-$0.0494 (+/-8.35%) up or down from last closing price. If Rallybio Corporation takes out the full calculated possible swing range there will be an estimated 8.35% move between the lowest and the highest trading price during the day.

Since the stock is closer to the resistance from accumulated volume at $0.625 (1.25%) than the support at $0.578 (6.42%), 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.

Is Rallybio Corporation stock A Buy?

The Rallybio Corporation stock holds several negative signals and despite the positive trend, we believe Rallybio Corporation will perform weakly in the next couple of days or weeks.

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