There is an age-old rule for figuring out how much of your portfolio to put in stocks - just subtract your age from 100.

But with a five-figure portfolio 100 per cent weighted to equities, Lim Bing Li is clearly not one to abide by conventional thinking.

The 23-year-old undergraduate believes that his aggressive investment style will blaze a trail to his long-term goal of financial independence by age 40.

The second-year Singapore Management University (SMU) student reckons that his youth justifies the steep risks as he is "ultimately investing for the future".

"But I feel I'm even more conscientious than I'm aggressive," Mr Lim said. "As my funds are limited, I always do my due diligence before every investment in order to maintain a high win-rate."

Mr Lim is currently studying for a double-degree in business and economics and is also the president of the SMU E.y.E Investment Club.

He plans to seek an investment banking job after graduation. "I only view investing as a means to an end," Mr Lim said. "What I really want is to achieve financial independence. This frees up time to allow me to do other things that I find value in."

Q: How did you handle money when growing up?

A: I started saving when I was young.

I saved a lot from the pocket money I received from my parents and put my savings in the bank.

But as I grew up, I realised that just saving wasn't enough, and that's when it struck me that investing in stocks was the best way.

Since then, I've been putting aside money in the bank, knowing that I'll invest in the future.

Q: Do you spend more or save more?

A: They are more or less equal, as I keep my spending at about 40 to 50 per cent of what I earn.

I usually spend on holidays and on going out with friends.
