Assessing the Swings

There are multiple methods to gauge the trading amplitude of a stock throughout the trading session. The difference between trading session highs and lows can be expressed in the number of trading ticks, that is the number of minimum price moves from the sessions high price to low price.

By itself, tick ranges can provide an insight into how responsive the stock is to changes in day-to-day sentiment. However it does not provide a full gauge of intraday volatility, as everything is relative and highly priced stocks will typically have higher tick ranges than much lower stocks.

Expressing daily trading ranges as a percentage of the price of the stock can achieve a more comprehensive gauge. Prices generally change throughout the trading day, hence the VWAP measure is typically used for this measure.

For instance, STI constituent Jardine Matheson Holdings (‘JMH’) might average 90 ticks during a trading session, however as a function of the share price, the 90 ticks represent just 1.1% of its VWAP. Whereas Golden-Agri Resources might average just a two tick daily trading range, however as a function of its VWAP, this could be as high as 3.0%.
