Is it safe to invest in a mutual fund scheme with high assets under management compared to its peers? HDFC Top 200, HDFC Equity Fund and Reliance Growth Fund have high AUMs and hence the concern.
Your concerns are valid; however, there is little empirical evidence to point at high AUM impacting performance or aiding it. In fact between the three schemes other than Reliance Growth the other two are amongst the best performing funds and have been consistent with their performance for long. What you need is to look at the performance of the funds you invest in compared to its benchmark as well as peers before investing in them.
