This circuit breaker has given me plenty of time and I have finally managed to compute my portfolio performance vs the index. I have been keeping track of every single stock transactions that I have made ever since I bought my 1st stock. The recent plunge in the market made me ponder that if I am spending quite a fair bit of time and effort to research stocks but I can't beat the index, I might be better off investing in the index funds.

As such, I decided to calculate my portfolio performance vs the index and I have been spending the past few nights to calculate the transactions for the past 10 years.

The calculation method used is the 'Unit Value Pricing' method. I first came across this method in the Valuebuddies (previously known as Wall Straits). There's still some old posts back in 2011 found here.

I've also found a reference...
