Adjusted Closing Price
Adjusted closing price restates historical quotes for specified corporate actions, helping compare returns without mistaking splits for gains or losses.
Share prices, equity indexes, appreciation, and volatility describe different aspects of stock performance, with adjustments needed for valid comparisons.
A stock quote, a market index, and a volatility estimate answer different questions. Share price describes a price for one share; a share price index combines selected stocks using stated weights. A higher numerical quote or index level does not, by itself, mean better performance or better value.
To compare dates, distinguish stock appreciation from returns that include dividends. Check how adjusted closing prices treat splits and distributions before calculating a gain. Corporate actions can change the quoted price without creating an equivalent change in a shareholder’s wealth.
Stock volatility describes return variation, not direction or a guaranteed loss limit. Compare estimates only after checking their lookback periods, data frequency, and whether they come from historical returns or option prices.
