No use, worrying individually about inflation. It will happen. Beat the inflation, Warren's way.
(8) "Long ago, Sir Isaac Newton gave us three laws of motion, which were the work of genius. But Sir Isaac's talents didn't extend to investing: He lost a bundle in the South Sea Bubble, explaining later, 'I can calculate the movement of the stars, but not the madness of men.' If he had not been traumatized by this loss, Sir Isaac might well have gone on to discover the Fourth Law of Motion: For investors as a whole, returns decrease as motion increases." - Warren Buffett
I agree. But, People are greedy and go on shuffling Portfolios constantly. A few successful investors like warren, stick with a well chosen Portfolio for years, even decades.
Since you always adopt either this or that option and not both - there is possibly no way of proving or disproving this Law to your self - which of the 2 options is better.
The truth of this Law depends primarily on one condition. You must research well and locate a good growth stock first. Then stick with it, forever.
Much like a marriage. If you ab-initio, locate your near-perfect match and stay put, your marriage is a grand success. Else, you can go on shuffling your spouses life long, to locate the perfect one, till the last.
By the way - there is neither a perfect spouse not a perfect growth stock. A good one is good enough.It eventually becomes a great one.
