@Rafi_Syed My buy approach is simple and many times I tend to buy stock at high price if I liked it. I follow staggered approach of building the stock allocation. I always buy very small and keep on buying till my desired level is reached and then I stop buying. Averaging down is done only on significant fall as per my statistical analysis. Stock inclusion in PF is never done on price consideration. Business understanding and long term accrual benefit is the only criteria.
I follow Peter Lynch and Graham approach. I am a firm believer in diversification
Hope this helps.
