Dear Mr. Shri,
I would first like to clear a few myths that you have been living with:
1. Gold BeES is not a share. It is a Gold ETF.
2. Gold BeES will require you to pay a brokerag at the time of entry and exit both.
3. The entry and exit load you are referring are the terms associated with Gold Funds. Just for your knowledge, there are no entry loads in Gold Funds (if you go through the right advisors) and no exit loads if you are planning to hold for more than one year.
Whether to wait for buying or not, its a decision you will have to take. The prices could move eitherways, but in my opinion, chances of moving down are relatively higher.
Hope this helps.
