I personally don't like gold funds as they carry double expense charges, 1 of exit load and other fund charges which are too high as cost of carrying certain % of real gold in fund portfolio increases expenses. Reliance gold saving carries 2% exit load and 5% expense charges. You lose 7% as you put money in sip everytime, if your view is short term or 5% atleast in longer term. Better is stay with etfs. More better etfs are as they can be bought in small quantity at every big fall and in an sip you have to put a pre-determined price at certain date.
2ndly, your theme based funds choice is good only if you are a) bullish on sector and b) have a long term view. And banks or power won't betray you in long run but you have to have heart of stone to reap benefits. Think about person who must have bought sbi at 200 and icici in ipo at 500, now have multifolded returns thanks to dividends, bonuses and price rise. In compare NHPC, rel power or alikes are still below issue price. So key for both sector is long term. Powers cycle will change if not today, after 2 years or 10 years.. who knows.
Instead of HDFC 200/HDFC equity you can choose SBI magnum equity or dsp br 100 reason stated above by asterix with small correction, hdfc equity, 200 and prudence all have identical funds. So for balanced fund prudence or hdfc balance is good choice but large/multi cap go for some other fund viz dsp br 100 or uti dividend or i-pru bluechip or magnum equity.
Reliance oppor is a good choice but again it matches with HDFC equity so struck out HDFC equity, though funds shuffle portfolio often, both managers have same investment mentality. Finally a pinch of midcap/lifestyle/multinational funds will be beneficial in long run considering India growth story. HDFC mid cap, UTI MNC or Magnum global, kotak lifestyle or birla pure life may give good returns in long run. Any of the ways, a good mid cap fund is a must in portfolio to get higher returns in compare to large/multi/theme funds.
