Holding period for shares

I just been informed by Ms Teh Hooi Ling in her article in yesterday's BT that there is a formula used to measure average holding period.

What is the formula?

It is calculated based on the annualised value of stocks traded in a month divided by the entire market cap of the stock exchange and multiplied by 365 days.

Last month ie. July 2007, the number of days a stock is held by investors in Singapore last month hit 353 days. It is the second lowest level in the last 17 years since the dotcom bubble in June 1999.

For the record, it was 309 days in June 1999.

So is it good or bad to have "a low holding period"?

Back in 1994 and 2000, average holding periods during thes 2 years dropped to the lowest level during their respective peak of the stock market.

And two months back, holding periods for stocks in Asia was at its briefest, shorter than even in 1994 and 2000.

Thus on hindsight, the correction should have been seen to be coming.

Lesson learnt - Set up the formula in your Excel spreadsheet and monitor it for the next stock market crash!!!
