Investors looked to diversify their portfolios in the last week, with shares in banks and mining companies proving popular.
Investor buys increased by a third in the week ending Tuesday 27 September, while the number of sales fell by a fifth, figures from TD Waterhouse show.
As a result, the number of stock buys outsold sales by a ratio of 1.3:1.
The majority of activity was driven by mining stocks and big bank trades, with the two markets making up nearly 60% of all top ten trades combined.
Barclays was the most bought equity in the week, rising from third place in the top ten buys last week.
Falling from top spot was Lloyds Banking Group, which proved to be the second most popular stock among investors over the week.
Aviva moved up the buys table to take third place; its share price slipped towards the end of last week on growing fears about the insurance giant's exposure to the debts of troubled eurozone countries.
The company's share price hit a week low of 268p on Friday (23 September), but rebounded at the beginning of this week, closing at 308p on Tuesday (27 September).
Royal Bank of Scotland Group also featured in the top ten buys as the fifth most purchased stock.
Darren Hepworth, trading and customer services director at the equity broker, said that customers' attention was also focussed on fluctuating mining stocks during the week.
Mining prices have suffered mixed fortunes in recent times as the global financial problems have led to fears of falling demand for commodities.
"Rio Tinto entered the buys in sixth position, two places behind top ten regular, Xstrata Plc, which rose three places on last week to fourth," added Mr Hepworth.
"Other new entries to the top ten buys table included Kazakhmys at seventh place and Antofagasta and BHP Billiton Plc, which both entered the table in ninth and tenth places respectively."
