More than 1,000 entries have already been received for Sharetrack 100, the fantasy share-dealing competition run by The Irish Times in association with Goodbody Stockbrokers.

Registration for the competition remains open until midnight on Sunday, April 29th. But those wishing to avail of a portfolio bonus of 50,000 in addition to their imaginary purse of one million must register by midnight tonight.

Contestants signing up after this date but before midnight next Friday will receive a portfolio bonus of 25,000.

An overall first prize of £15,000 (€19,000) will be awarded to the person whose portfolio has the highest balance at the end of the competition on Friday, July 6th at 5.30 p.m. Second prize will be £7,000 and third prize £3,000.

Weekly winners throughout the competition - contestants whose portfolio values have increased by the greatest percentage in a week - will be awarded £1,000 and one year's commission-free share dealing through Goodbody.

A contestant's portfolio must contain eight companies from eight different sectors. Between £100,000 and £200,000 can be invested in each company.

Strategy is key - investors should remember that they are not investing for the long term, just the three-month period of the competition. Two companies must be selected as core holdings, which are non-tradeable and must be held for the duration of the competition. Contestants can then select the remaining six from any other sector. They can make one amendment to their portfolios each week.

For further information about the companies to be traded and their sectors, there is a comprehensive list on the Goodbody Stockbrokers website, www.goodbody.ie
