TheStreet.com ratings take into account both the performance and volatility of a company's stock, so when markets are in turmoil there are bound to be changes.

Here's a look at how our top-20 rated closed-end funds and exchange-traded funds fared during the tumultuous month of February.

As the charts below illustrate, they did relatively well in February.

For purposes of comparison, we have separated the funds with a track record of greater than three years from younger funds with less than a three-year track record. (We rate closed-end funds and ETFs with a track record of at least 12 months.)

Most of the older funds are ETFs from Barclays iShares, but two are closed-end funds --

Mexico Fund

(MXF) - Get Report

and

MVC Capital

(MVC) - Get Report

.

A further distinction is that all but one of the older top-rated funds invest overseas, with the exception of MVC Capital.

MVC is a business development company that provides long-term equity and debt investment capital to fund growth, acquisitions and recapitalizations of small and middle-market companies.

Below is the list of the top 10 rated "younger" funds, the composition of which varies notably from that of the older funds above. If we look in the "type" column, we see that there is more of an eclectic group compared with the more established funds. Included on the list are a couple of mid-cap funds, a large value fund, a defense fund and a utility fund.
