The I-fund does not use an index fund such as the Nikkei 300.
Well, true. It does not use the Nikkei 300 as an actual vehicle to trade.
Instead, the "I" fund tries to reflect the Morgan Stanley EFA fund, which is composed of a number of stocks. As of the end of September, there were 830 stocks worldwide in the EFA, which make up the target of the "I" fund.
The Japan componet of the EFA is more than just what is in the Nikkei 225, historically it looks more like a reflection of the Nikkei 300.
Here is the actual component list of the Morgan Stanley EFA, as of the end of September:

Japan stocks make up about 22% of the "I" fund's value.
As noted by a poster above, the price this morning of many of those stocks is ABOVE the overall price increase in the Nikkei 225 and AORD, in fact it's darn close to the value of the Nikkei 300. So we use the Nikkei 300 as a compent in calculating what the "I" is going to do.
When over 22% of your portfolio is up over 2.25% in a single trading session, that is a good way to start the day. Now we have to wait and see what the Europeans will kick in this morning to the mix.
