Historical volatility is basically how a stock's price has been playin' around over time, based on what went down in the past. 📈
It checks out how spazzy a stock price normally is during a specific time frame.
To nail this, peeps usually peep the daily (percent price changes in a stock, then they do some math magic to find the standard deviation over a vibe check period.
That standard deviation gets dressed up as an annualized percentage — fancy, right? 🎩
Historical volatility got its other aliases too: actual volatility or realized volatility, just to keep ya guessing. 🤔
People who are all about that short-term trading life go for snappier time frames to measure historical volatility — talking five-day, 10-day, 20-day, and 30-day kinda deals.
The chill, long-term squad opts for dragging this whole thing out, usually vibing with 60-day, 90-day, 180-day, and even 360-day checks. 😎
