AlphaGBM Take-Profit Strategy Lab

Answer one question mechanically for any ticker: Can you just hold it, or do you need to actively take profits? Most retail losses come from poor exits, not poor entries. This skill quantifies the exit decision with 10 years of daily data.

The Core Metric: Rollercoaster Rate

A "rollercoaster event" happens when an entry's paper profit exceeds +50% and then falls more than 50% from that peak before exit. Example: enter at 100, peak at 190, fall back to 90 — you didn't lose money, but the 90 of peak profit you "touched" evaporated, and the journey was brutal.
