For the upcoming trading day on Friday, 26th we expect Repligen Corporation to open at $144.82, and during the day (based on 14 day Average True Range), to move between $141.82 and $148.64, which gives a possible trading interval of +/-$6.81 (+/-4.81%) up or down from last closing price.

Is Repligen Corporation stock A Buy?

Repligen Corporation 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. 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 Hold candidate.

Current score: 0.000 Hold/Accumulate Downgraded

Zero in score indicates that our system is expecting high volatility and risk for the following trading day. Given the latest developments, we cannot determine the next direction as it may go both ways.
