TIMING IS KEY - If you have an eon to wait, but as Keynes said “in the long run we are all dead,” buy and hold (if you've got the right investments) does work. But in the modern, volatile world where investment results are measured more frequently than in eons, or even in the long run, changes in capital market prices almost always have a greater bearing on investment results than do dividends and interest.
Thus timing of purchases and sales plays a very important role in investment decisions. And this is where Before the New$ comes into play.
