Frequently asked

Questions about this quote

What APH historical data does TECHi show?

TECHi shows dated Amphenol Corp. closing prices, with high, low, volume, dividend, and split columns whenever those values are available for the session.

How does TECHi calculate APH 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 APH price history?

The APH 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 APH 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.
