If a StarBond has risen a lot, this means a lot of players are holding it long. Many will liquidate soon after the adjust by selling. This alone forces the price down. Even more anticipate the loss, even short term, and they short, forcing even lower prices. Granted, NOT ALWAYS, expeciallly if the price approached the adjust price a week or so ahead of the adjust, or ir the next adjust is in the next 2 or 3 weeks.
Similarly, if the price fell sharply, the market forces will cover/buy forcing a gain.
When I took over the BONDS fund, I asked "How long should I hold the bounce" and the answer I got is not how the fund does it. I have found a way to use radars to monitor the change of direction.
For some reason, today at 1045 am, EDT, playing the bounce, I think the fund is up more than yesterday, the day of the adjust.
I have also advocated the use of coded share amounts to tell you what you intend to do. One amount might mean dump the bond when the bounce reverses, another code might mean to reverse position. This is up to you.
But you have to remember that at times you are "playing the players"
