Fair value estimate
No estimate for AMPX: negative free cash flow. We’d rather show nothing than a made-up number.
Risk vs market
How risk vs market is measured
One year of daily returns (Oct 31 to Nov 2, 252 sessions). Beta = how much AMPX moved for each 1% move in the S&P 500 (SPY); 1.0 moves with the market. Volatility is the yearly standard deviation of daily returns. Past behavior, not a forecast.
Swings much more than the market, and its own price swings are 7.7× the S&P 500’s.
