Castle Biosciences Stock Forecast

Buy or Hold candidate since Oct 21, 2025 Gain 45.09%

The Castle Biosciences, Inc. stock price gained 1.49% on the last trading day (Monday, 17th Nov 2025), rising from $33.45 to $33.95. During the last trading day the stock fluctuated 3.56% from a day low at $33.19 to a day high of $34.37. The price has been going up and down for this period, and there has been a 30.63% gain for the last 2 weeks. Volume fell on the last day by -137 thousand shares and in total, 330 thousand shares were bought and sold for approximately $11.19 million. You should take into consideration that falling volume on higher prices causes divergence and may be an early warning about possible changes over the next couple of days.

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 $35.61 will firstly indicate a stronger rate of rising. Given the current short-term trend, the stock is expected to rise 40.70% during the next 3 months and, with a 90% probability hold a price between $35.91 and $50.11 at the end of this 3-month period.

CSTL Signals & Forecast

The Castle Biosciences, Inc. 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 $34.16. On a fall, the stock will find some support from the long-term average at approximately $26.40. 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. Furthermore, there is a buy signal from the 3 month Moving Average Convergence Divergence (MACD). Volume fell during the last trading day despite gaining prices. This causes a divergence between volume and price and it may be an early warning. The stock should be watched closely. 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 -2.92%. Further fall is indicated until a new bottom pivot has been found.

Support, Risk & Stop-loss for Castle Biosciences, Inc. stock

Castle Biosciences, Inc. finds support from accumulated volume at $33.57 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 $1.18 between high and low, or 3.56%. For the last week, the stock has had daily average volatility of 3.10%.

The Castle Biosciences, 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: $32.67 (-3.77%) (This stock has very high daily movements and this gives very high risk. The RSI14 is 83 and this increases the risk substantially. There is a sell signal from a pivot top found 4 days ago.)

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

For the upcoming trading day on Tuesday, 18th we expect Castle Biosciences, Inc. to open at $33.84, and during the day (based on 14 day Average True Range), to move between $33.27 and $34.63, which gives a possible trading interval of +/-$1.36 (+/-4.07%) up or down from last closing price. If Castle Biosciences, Inc. takes out the full calculated possible swing range there will be an estimated 4.07% move between the lowest and the highest trading price during the day.

Since the stock is closer to the resistance from accumulated volume at $34.12 (0.50%) than the support at $33.57 (1.12%), 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 Castle Biosciences, Inc. stock A Buy?

Castle Biosciences, Inc. holds several positive signals, but we still don't find these to be enough for a buy candidate. At the current level, it should be considered as a hold candidate (hold or accumulate) in this position whilst awaiting further development.

Current score: -0.020 Hold/Accumulate Unchanged
