I use to buy star bonds by projecting far down the road, but have lately been holding off until the calendar is updated. And even then, quite often I'm still able to catch many of them for a good price / profit. Sometimes, when they have another delisting movie coming up (3-6 months, or maybe even the following week), I'll 'flip' them or keep them. Most of the time I simply cash out, and that seems to have been working out quite well.
I use to have hundreds of positions, but now it's a more management (at least to me) number. Plus, I no longer have millions tied up on bonds which may not adjust for year or later.
