Recently, the industrial and defense sectors have felt very stable. Eaton and Caterpillar are practically a perfect blend of defensive and growth attributes. It's better to just focus on the heavy industry leaders yourself rather than buying an ETF. It's hard to regret holding these if you actually have a position.

Those two US defense stocks—Lockheed Martin and Raytheon—although they haven't been very volatile, the money just won't leave. Honestly, at this level, you don't want to take a loss by selling, but holding on makes you afraid of missing out on a rally.
