Traders experienced a severe case of whiplash this week, as markets of just about every stripe staged sharp reversals following reassuring comments from Federal Reserve Chairman Ben Bernanke.

But with the exception of stocks, chart watchers believe the reversals seen in markets such as Treasurys, emerging markets, currencies and gold are temporary. It won't be long before previous trends reassert themselves, they say.

"You're getting the excitement of one day, and one comment," says John Schlitz, chief U.S. market technician at Instinet.

For weeks investors had been fretting about the potential impact of the Fed pulling back on its easy money policies. Those concerns sent U.S. Treasurys prices sharply lower and yields rocketing. The dollar surged, gold prices slid and emerging-market stocks also sold off sharply. U.S. stocks, which had been record territory in May, fell back from their highs.

Then, late Wednesday, the outlook changed. Mr. Bernanke soothed concerns by saying that the Fed's highly accommodative policy was needed for the foreseeable future. Overnight, markets changed direction.

In the stock market, Mr. Bernanke's comments helped push the S&P 500 to an all-time closing high of 1675.02 on Thursday. On Friday, the index inched fractionally higher in midday trading.

Meanwhile, the yield on the 10-year Treasury declined to 2.552% from 2.683% just prior to Bernanke's comments late Wednesday. Since then, the iShares MSCI Emerging Markets (EEM) exchange traded fund has surged nearly 4%, July gold futures rallied more than 2% and the ICE U.S. Dollar Index slumped close to 2%.

When it comes to Treasury yields, the recent uptrend started in early May, which was before Fed officials made it clear that less stimulus was likely, in the form of reduced asset purchases. Therefore, Mr. Schlitz sees no reason to think Mr. Bernanke's comments will reverse the trend for good. "I don't believe just because [Mr. Bernanke] says what he says, the yield is going to unwind everything," he says.

The yield on the 10-year has been climbing sharply since hitting a multi-month low of 1.614% on May 1. On May 21, the yield closed at 1.944%. It was on May 22 that Mr. Bernanke sparked tapering fears, after he indicated the Fed could start reducing the pace of asset purchases over the next few months.

Bank of America Merrill Lynch technical strategist MacNeil Curry says the yield on the 10-year could slip a bit further in the near term, to key support at 2.463% to 2.372%. But he says the "larger ... trend remains intact." He sees the yield rising to an initial target of 2.857% to 2.951%.

It's a similar story for emerging market stocks, chart watchers say. Strategas Research Partners technician Chris Verrone says the iShares MSCI Emerging Markets ETF could rise a touch more, but believes the rally was just a temporary, countertrend bounce. "I'm not too interested in chasing this bounce," he says. "It's one that I'm still inclined to fade."

EEM was trading at $38.89 midday Friday, and was down 12% from its mid-May high.

Both Mr. Verrone and Instinet's Mr. Schlitz see significant resistance for EEM starting at the $40 level.

"There's really nothing in the charts to suggest the [EEM] rally is anything more than just a short-term bounce," Mr. Schlitz says.

In currencies, the dollar fell on Mr. Bernanke's remarks, and the euro rose to a three-week high above $1.32. The currency pair was last at $1.3054.

Mr. Curry says dollar weakness will prove "temporary and corrective before the larger [bull] trend resumes." His target for the euro against the dollar remains around $1.2457.

And despite gold's jump, the futures price remains well below the widely watched 50-day moving average, which technicians use as a gauge for the short-term trend, at $1,358.98. July gold futures were recently at $1,276.30 an ounce.

But when it comes to U.S. stocks, it's a different story. The post-Bernanke rally is expected to continue. The basic reason, technicians say, its that U.S. stocks were already on an established trend higher before Mr. Bernanke made his comments.

The Russell 2000 small-capitalization index reached new record highs last week, and the Nasdaq Composite broke out to a fresh decade high on Tuesday, suggesting the larger-cap indexes were likely to follow. On Friday, the Nasdaq was up 0.1% at 3583 and the Russell 2000 rose 0.3% to 1036.

"Secondary issues [like small caps] are leading, and I believe that's important," says Strategas's Mr. Verrone.

"The more stocks that are rising, the better it is for the overall trend, he says.
