Daily STM open, high, low, close, and volume bars. Split-adjusted closes by default; return, range, and realised volatility are computed from the same series.
Trend read
STM sits in the top 1% of its 52-week range. Stocks holding above the upper band of their range tend to attract trend-followers; the cleanest signal here is whether realised vol is rising with price (continuation) or compressing (consolidation).

Frequently asked
The STM 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 STM bars by default; the underlying provider feed reaches back to STMicroelectronics NV'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.
