Drawdowns of the S&P 500, KOSPI, Nikkei or any stock from full daily data: past declines, recovery times and returns a year later. Yahoo Finance, not advice.

Log price and drawdown from the record close

Shaded spans are declines at or above the threshold (darker: peak to trough; lighter: trough back to the old peak). Dots mark each trough. Everything is measured on daily closes, so intraday lows do not show.

Peaks and troughs are closing prices, so they differ from intraday highs and lows. Highs set before the record begins are unknown, so declines near the start can look shallower than they were. Tap a row to zoom the chart to it.

What this tool does

This tool uses real market data to show how far a stock index such as the KOSPI, S&P 500, Nasdaq, Nikkei 225 or Dow (or any stock you choose) has fallen from its highs in the past, and how long it took to get back. It shades each decline on a log price chart and adds a drawdown (underwater) chart, a list of declines above a threshold, where the index stands against its record today, and a list of past cases showing what happened 6 months and 1 year after the index had fallen by the same amount.

How it is calculated

Prices come from Yahoo Finance through our server. The tool loads the full daily history Yahoo has for each symbol once, and separately loads the last 3 months of daily bars to add new values (every 5 minutes while the market is open, every 30 minutes when it is closed). If Yahoo has no daily bar yet for the latest day, that value comes from the latest quote, and the note under the chart says so. Drawdown = that day's value ÷ the highest value up to that day − 1. Declines use closed bars only: a decline starts at a record value, reaches at least the threshold (10%, 20%, 30%, or today's drawdown rounded down to a whole percent, offered only when it is at least 5%), and ends on the day the old record is regained. The 'What followed' table collects, for each peak, the first day the threshold was reached (once per peak) and records the return from that day to 182 and 365 days later (the next trading day if that date is a holiday; the cell is left blank if the next trading day is more than 45 days away). The comparison line measures the same 1-year return from every month-end on record (excluding the unfinished current month), and 'Months deeper than now' counts the same month-end sample. Indices are measured as price indices without dividends; stocks and ETFs use the adjusted close (dividends reinvested) by default, and you can switch to the closing price.

Things to know

Frequently asked questions

How is the drawdown calculated?

Divide the day's closing price by the highest close up to that day and subtract 1. It is 0% on a day that sets a new record close and grows more negative as the price falls. A decline ends on the day the old record close is regained. Because it uses closing prices, it is slightly shallower than a drawdown measured from intraday highs and lows.

How far back does the record go?

The tool uses the full daily history on Yahoo Finance. For the main indices that starts in December 1927 for the S&P 500, January 1965 for the Nikkei 225, February 1971 for the Nasdaq Composite, January 1992 for the Dow and December 1996 for the KOSPI; individual stocks start wherever Yahoo's record does. The span and bar count actually used are listed under the chart. If Yahoo ever returns the full history only as month-end closes, the tool puts those closes in front of the last 10 years of daily bars and says so; deeper lows between month-ends are then missing, so older declines can look shallower than they were.

Does the 'What followed' table predict the future?

No. It is a record of the past days on which the drawdown first reached the threshold, with the returns that actually followed. Each peak is counted only once so a single decline is not counted several times. There are few cases and every era was different, so even for the same index the 1-year results vary widely. The comparison from all month-ends is shown because the cases alone can look more special than they are.

Why are stocks and ETFs measured on the adjusted close?

Individual stocks and ETFs use the adjusted close by default. It assumes dividends are reinvested and scales past prices down accordingly, so drawdowns and 1-year returns come closer to what a shareholder who received the dividends actually went through. The more a stock pays out, the shallower its drawdowns and the faster its recoveries look compared with the closing price. The peak and trough values in the table then differ from the prices you are used to seeing, so press 'Price' to measure drawdowns on the closing price instead. Indices such as the KOSPI and S&P 500 are price indices without dividends, so the option does not appear for them, nor for symbols whose two values are identical.
