Hi Sir Hank
We usually read current market commentary from various sources/investing outlets like vsnguard schwab Fidelity marketwatch seekingalpha etc.. from these news we would considet adjust our portfolio into different stocks or funds accordingly. We are indeed buy and hold investors. Have not sell much in 2008 or 2020 crash. We usually try buy more if market decline further. Our plans are to keep diversify our holdings, wait until few years retirement then change our position to high bonds/cash/fixed-income positions.
To risk stratification mean to change our positions to different or add more to various vehicles (like energy bonds hard metals etc). Recently we did sell more bonds and added more stock oast 9 12 months.
As you can see we did reasonably well 10 years return 7.8% annually.
For buying individual bonds we look at Cusip, read company valuations from schwab, see any red flags or bad ratings, any default possibilities, set up alert news about the bond, and then
