Relative strength

Cumulative lead over the S&P 500

Above 0 = ahead of the S&P 500 since the window start; below 0 = behind. Rising means it's pulling ahead.

Downside

Drawdown from peak · max -34%

How far the stock fell below its prior peak. Deeper, longer drawdowns = a rougher ride to the same return.

Quarter-end, dividend-adjusted (total return). Beta & volatility from quarterly returns (annualized). Benchmark is the S&P 500 (SPY total return). Annual returns compound the quarters ending in each calendar year; the first and last years in a window may be partial. Past performance doesn't predict future results.
