Frequently asked
The CLS Historical Data page renders OHLCV (open / high / low / close / volume) rows and return calculations. The Chart page is the visual companion for longer timeframes.
TECHi shows 1 year of daily CLS bars by default; the underlying provider feed reaches back to Celestica Inc's IPO date. MAX-timeframe loads the full history for chart visualisation.
Yes — TECHi displays split-adjusted closes by default so the visual story is not broken by a stock split. The page labels the historical series used for return and volatility calculations.
Total-return calculations (price + reinvested dividends) ride on the same OHLCV table; the column labelled "Total return" backs out the dividend reinvestment so backtests stay honest.
