Frequently asked

Common questions.

What SIMO historical data does TECHi show?

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

How does TECHi calculate SIMO 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 SIMO price history?

The SIMO table runs through the most recent completed trading session in the series, and every row is dated so you can see exactly how current the latest bar is.

How much SIMO 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.

How to use this page

Use this to put the current move into long-range context.

Best for Drawdowns, period returns, volatility clusters, and dated price ranges.

Weak when Recent corporate actions or sparse observations distort the displayed baseline.
