During the fourth quarter of 2011, the total volume of day-trading fell 38.4% when compared with the preceding quarter, plunging 42.0% on a year-over-year basis. On average, the volume of trades per financial intermediary dropped 38.4% from the 3rd to the 4th quarter of 2011 (-38.0% on a year-over-year basis). The 'price effect' contributed towards this as the PSI-20 depreciated 7.9% over the same period. The day-trading weight on the share turnover in Euronext Lisbon tumbled in comparison to the preceding quarter losing 1.5 percentage points being set at 6.9%. (Tables 1 and 2)

In the fourth quarter of 2011, 81.5% of day-trading was carried out by retail investors and 18.5% by institutions (excluding the Financial Intermediary's (FI) own portfolio), indicating a sharper decline of the value traded by retail investors as against the decrease in transactions by other institutional investors. Among institutions, asset management displayed 12.0% of the total day-trading (9.1% in the preceding quarter) and the 'other investors' 6.4% (6.5% in the previous quarter). (Table 4). 68.9% of orders were transmitted through the internet (71.7% in the preceding quarter); 24.0% were by telephone, in person or by fax (20.8% in the previous quarter) and 7.1% through other channels (7.5% in the 3rd Quarter of 2011). (Table 4)

Resident investors were responsible for 98.9% of day-trading and non-residents a mere 1.1% (excluding FI's own portfolio) in the 4th quarter 2011. In comparison with the previous quarter, there was a 1.3 percentage points increase in the weighting of residents. Among resident investors, the main volume of day-trading deals arose from retail clients (81.7%); as for non-resident investors, the main volume was due to retail investors (64.1%) which reverses the historical trend, depicted, for example, in the prior quarter, wherein institutional investors accounted for 75.0% of the total amount traded in Day-Trading by non-resident investors. (Table 5)

As for the type of FI that carried out day-trading, the credit institutions were responsible for 92.2% of the total day-trading volume in the fourth quarter of 2011. The weight of investment firms was 7.8% in the same period. (Table 3)

The day-trading deals were largely implemented by the FI's client portfolios. 98.0% of the volume was carried out by third-party portfolio and 2.0% by own portfolio. With regard to turnover, the day-trading deals nosedived 81.6% when compared to the previous quarter, whereas the third-party portfolio deals fell 39.3% on a year-over-year basis. (Table 6)

As to the degree of market concentration, the three FI's with the largest market share were responsible for 44.6% of day-trading volume in the fourth quarter of 2011 (a decline of 1.3 pp when compared with the 4th quarter of 2010). According to the Herfindahl-Hirschman Index, slightly higher concentration levels than those in the previous quarter were recorded. (Table 7)
