In almost every circumstance high expense ratios are a bad idea.
I would say every circumstance, but I don't want backlash from anyone.
There are many other investment companies out there that offer mutual funds for FAR less than 1.5% ratio. I couldn't even imagine paying a 1% expense ratio for a mutual fund.
Vanguard offers mutual funds that are significantly lower, on average, than the industry. Certainly MUCH lower than 1.5%, but then again I'm not sure what mutual funds you have, stock, bonds, etc.
Here is a list of all Vanguard's mutual funds. I honestly like the company a lot, many people haven't heard of them because they don't spend nearly as much money on advertisements or a flashy website - but they have extremely low expense ratios. You can buy into many of their mutual funds with a 0.10%-0.20% expense ratio. Some are higher, but certainly not even close to 1.5%. I don't believe any of them are even half of that.
Also, if you were referring to ETF's when you mentioned Index Fund (assuming that since you have ETFs in your tag), then 0.20% for ETF's is steep, check out some identical ETFs on Vanguard.
I am not a Vanguard employee soliciting their service to you. I'm just trying to pass on good information to another investor. I believe you can buy vanguard funds through other investment companies, like Fidelity, for a good price, but I prefer to go through them.
