<prompt> Human: Im 32, single wno kids, and the modest mortgage I took out on my home 3 years ago is my only real debt.My combined investments ended 2017 at about 112,000, the large majority of which are in ETFs with costs in the 0.20-0.60 range. I have 75 in domestic equity split among largemidsmall and valuegrowth, 10 bond fund, 10 international, and 5 tech sector ticker FDN.While I feel a market correction or recession is bound to occur at some point, I am content with my allocation. I am old enough to have successfully stayed the course through 2008, and young enough to stay the course should it happen again.As the title said, my 2017 returns are quite close to the overall markets. I realize part of that is because my portfolios composition does mirror the broader market, so similar returns should be expected. But Im trying to figure out what the benefit is to me of my current allocation versus a portfolio thats much heavier on low-cost index funds.Im not seeking to make a rash decision such as selling my funds off now and moving to index fund ETFs, particularly because Id have to claim a large chunk of capital gains. Im more in the mindset of considering that option should a market correction occur, where I could move monies around with little tax consequence. Is it worth it to keep the diversity I have?  <response>: At least you didnt bet a million dollars against Warren Buffet!
