Turnover
Turnover in stock market terminology refers to the total value of shares traded over a given period, expressed in rupees (as opposed to volume, which is expressed in number of shares). NSE and BSE publish daily turnover figures as a measure of overall market activity.
While volume counts the number of shares traded, turnover calculates the monetary value of those trades — effectively, volume multiplied by the weighted average transaction price. For example, if 10 lakh shares of a stock trade at an average price of Rs 500 each, the turnover for that stock is Rs 50 crore. Summing turnover across all trades in a day gives the exchange's total daily turnover, a widely reported metric for judging market health and investor activity.
NSE's equity segment regularly reported daily turnover figures running from Rs 50,000 crore to over Rs 1 lakh crore during peak market activity periods. When India's options market experienced explosive growth after SEBI's regulatory adjustments around weekly options, derivative segment turnover figures reached extraordinary levels — sometimes in the hundreds of lakh crore rupees notionally — though notional derivatives turnover is not directly comparable to cash equity turnover. High turnover days typically coincide with major market events: Budget day, RBI policy announcements, or index expiry days.
For retail investors, turnover is relevant in a few specific contexts. First, it helps calibrate liquidity more accurately than volume alone, since a stock trading at Rs 1 (with high volume in shares) may have very low turnover and thus limited real market depth. Second, turnover is the base for calculating transaction costs — brokerage, STT (Securities Transaction Tax), GST, and exchange charges are all applied on turnover, making it directly relevant for understanding the cost of trading. Third, in mutual fund analysis, 'portfolio turnover ratio' measures how frequently a fund manager replaces holdings.
A critical distinction to remember is between cash market turnover and derivatives turnover. India's derivatives market generates far higher notional turnover than its cash equity market, a ratio that is unique globally in its extreme imbalance. SEBI has at times expressed concern about this imbalance, arguing that excessive derivatives activity relative to cash markets may reflect speculation without adequate hedging purpose. Retail investors should be careful not to mistake large derivatives turnover figures for cash market depth.
