“As a trader, you never ignore all-time highs. That’s usually a very, very strong bullish signal that suggests the market is feeling very positive about long-term trends,” said Boris Schlossberg, managing director of foreign exchange strategy at BK Asset Management.

As such, the gains in equities have been spilling over into ETFs as the iShares U.S. Aerospace & Defense ETF (Cboe: ITA), the largest aerospace and defense ETF, is up nearly 16% year-to-date. ITA’s peers have also experienced similar gains–PowerShares Aerospace & Defense Portfolio (NYSEArca: PPAis up 10.14% YTD and the SPDR S&P Aerospace & Defense ETF (NYSEArca: XAR) is up 15.255 YTD.

DFEN seeks daily investment results equal to 300% of the daily performance of the Dow Jones U.S. Select Aerospace & Defense Index, which attempts to measure the performance of the aerospace and defense industry of the U.S. equity market. With its triple leverage, DFEN has produced astounding results–23.31% YTD and almost 65% within the last 12 months.

A number of market analysts feel that this run in the aerospace and defense sector could continue even after the extended bull market loses its current momentum. According to MarketWatch investing columnist Philip Van Doorn, “stock prices tend to be driven by increases in earnings. The federal income tax cuts that went into effect this year will no doubt boost profits and potentially share prices. But that party will surely end, after which it is reasonable to expect the aerospace and defense subsector to continue to outperform the broader market.”
