When I made my first ever trade in the financial markets in 2003, I remember feeling that the day when I hold a substantial amount of index funds like the S&P500 or DOW would be the day I can say to myself that I have made it.
Back in those days, each trade was tagged with huge transaction fees. And you need to be able to constantly keep track of them unless you are a big trader with a lot of funds to burn.
Which is why buying and holding is the smarter way to play, especially when you have read just 1 book on Warren Buffett.
