 Historically, however, the values of the preferred shares of financially sound split share corporations have tended to keep relatively close to their respective wind-up values.In practice credit risk appears to be a greater factor in the valuation of the relatively thinly traded preferred shares as opposed to the value of alternative (and more efficiently traded) conventional fixed-income instruments like bonds.The capital shares of a split share corporation are intended to be a more aggressive investment vehicle, one that can provide both high income and the promise of amplified capital gains compared to the capital gains of the underlying basket of shares.
