Reference at 1970-01-02: 17.435. Equivalent latest reference value: 13,026.89 (+1202.69%).
Uses the last observation on or before the chosen date. Positive reference prices are required for amount comparisons. Excludes fees, dividends, interest and tax. Index results represent hypothetical proportional exposure.
How the source reference becomes the displayed data, indicators and planning scenarios.
Quote, history, forecast and calculators use the same Yahoo Finance chart snapshot. Source observation time and automated check time are shown separately. Price changes use the previous completed observation. Bond moves are basis points; index values are points.
Yahoo Finance supplies the named instrument reference and daily OHLC history. No placeholder catalogue prices, synthetic candles, or fabricated fundamentals are used.
25%-shrunk 60/40 blend of 30/90-session mean log-return drift with a model-implied central 80% lognormal interval from 30-session realized volatility; constant-volatility assumption, not empirically calibrated coverage Intervals are not calibrated empirical coverage; jumps, fat tails and parameter uncertainty are excluded.
Indicators use completed daily observations and require 200 samples. Composite = (Buy − Sell) / rule count: Strong Buy above 0.55; Buy above 0.15; Neutral above −0.15; Sell above −0.55; otherwise Strong Sell. Each browser checks every 60 seconds; provider snapshots are cached for up to five minutes. Failed refreshes are visibly marked.
Every planning band uses the same timestamped reference displayed above. Changing the annual assumption updates the scenario chart, yearly bands and regular-contribution calculations.
Lower and upper paths apply the selected annual change in opposite directions. The base path keeps the reference unchanged. These paths have no assigned probabilities and are separate from the short-term statistical model.
Prices use the instrument’s quoted units; indices use points and yield moves use basis points. Fees, taxes and distributions are excluded. A yield path cannot estimate a bond investment return.
Read as a range: short-term estimates and long-term planning scenarios can fall outside every displayed band. Source gaps and unsupported calculations are withheld.
The source span and observation count are shown above. Missing dates are omitted. Records refer to available source coverage, not the instrument’s entire lifetime.
Price changes compare observed reference values. Yield moves use basis points. Conversion amounts use the same timestamped source rate; spreads, fees and distributions are excluded.
A share reference represents a company equity instrument. Investment returns also depend on corporate actions and dividends. The source instrument is IBM, quoted as USD / share, with daily history.
Source quality: Single instrument provider for quote and OHLC history. The displayed check time is separate from the market observation time. Missing fundamentals are not estimated.
