They are between a rock and a hard place. By definition they are supposed to spread to avoid risk and yet as you say they lose because of it. I was just doing the math, our original purchase of AAPL, which our broker was dead against due to over weighting, is running at almost exactly a 1600% gain based on today's price. The stock our broker retained where he wanted and invested for safety is running 3%. In the end I guess it is a crap shoot for them.
