Judging by your post, I don't think you are too much into economics :) But let me try and give you a simple indicator: Keep an eye on the interest rates (or the discount rate as it is called). Presently it is at 9%. My guess is that by the end of the month, there will be a hike in rates. 10%-11.5% is a nonresponsive interest rate corridor for our economy. If the rates cross 11.5%, the stock market will start falling and property prices will stop rising (or atleast not rise rapidly). Untill then, I think we are fine. So the simple rule is:
Interest rates less than 10 % = Good for Speculation
Interest rates above 11.5 % = Bad for speculation
P.S. Dont get too confident on the rupee just yet, there is another IMF installment due on 26th August.
