typos and observations: first, my analysis was for an initial holding of 1000 units (not 100...thats just a sloppy typo by me). Probably many other instances of poor grammar and/or spelling.
Second; there is nothing here especially unique to KMR being an I-share. The same basic situation occurs with a cash-paying dividend company. The price of the investment falls by about the amount of the dividend on the x-div day. Except for non-dividend the market shifts, you are just as well off before the dividend date as after it (with the dividend in hand). In retrospect, my spreadsheet noodling shown me (the hard way) an old truth: you cannot game the market system by buying and selling right around a dividend date. You might find a particular angle based on taxes, but the market figures that out as well...your tax situation has to be different than the average tax situation that the market as a whole faces in order for there to be some sort of market fluke that you can pick up on. by round-trip trading right around dividend time.
