Yesterday, the markets delivered outstanding performance and some exchange traded funds (ETFs) finished up in the double digits.

But one good day doesn’t mean we’re out of the slump yet. It’s still time to take a defensive stance with your portfolio and make sure you’ve got that exit strategy firmly in place. But while it seems as though everything is in a downward spiral, but there are still some buying opportunities, believe it or not.

At our asset management firm, we track a list of about 100 ETFs and review it daily to see how things are performing and if there are any trends emerging. Of particular interest to us is which funds are above their 200-day moving averages. We never buy something sitting below that line.

Once we own an ETF, we keep an eye on it to make sure it’s still above that line and continuing to perform. Once it dips below the trend line or falls 8% off its high, we sell. No ifs, ands or buts. A sell strategy from which emotions are entirely removed is the only kind that will benefit any investor.
