Sensex hitting 15K and beyond

Today Sensex has touched 15000 mark and has slipped. With inflation on low, interest rates on high, the bulls are riding the market again. IMHO, the interest rates cannot go more and when it returns to normal levels, we may be seeing another spike in the market sentiments. Is the rupee exchange rate against dollar is worth in its current value. Are the Indian companies are over rated in their worth/value. Is their worth of their intrinsic values as Buffet says in his Essays to Investors? Only time will tell, but by the time people are trying to make money as much as they can. I suspect huge profit booking going to happen over the next week, but with new IPOs and NFOs, there is so much money with the AMCs, anything is bound to happen.
