Frequently asked
Common questions.
What GOOG historical data does TECHi show?
TECHi shows dated Alphabet Inc. (Class C) closing prices, with high, low, volume, dividend, and split columns whenever those values are available for the session.
How does TECHi calculate GOOG returns and volatility?
Returns use the displayed closing prices. Realised volatility is calculated only when enough dated observations exist, using the annualised standard deviation of daily log returns.
How current is the GOOG price history?
The GOOG table runs through the most recent completed trading session. While the cash session is open, today's unfinished bar is shown separately and is left out of returns, volatility, and the daily table.
How much GOOG history is included?
The table and summary use only the sessions delivered in the displayed series; TECHi does not infer older prices or fill missing dates.
