NEW YORK (TheStreet) -- U.S. bonds and silver closed strong on Tuesday, possibly setting up for a move higher ahead of Wednesday's Federal Reserve meeting.On Wednesday, markets will get commentary from the Federal Reserve, which is expected make no changes to current policy. The first chart below is of iShares Barclays 20+ Year Treasury Bond ( TLT). yesterday, defensive sectors such as Consumer Staples Select Sector SPDR ( XLP) have been outperforming recently, partly because low-beta, slow growth companies do well during times of uncertainty. As investors have rotated away from high-beta companies such as Tesla Motors ( TSLA), they have put funds in companies offering less capital appreciation. Defensive companies with lower growth also tend to offer attractive dividends, which can be enticing when bond yields are declining. The long-dated Treasury bond broke higher from its bottom range earlier in the month, but has since consolidated tightly. Prices have drifted lower in a holding pattern, but with the Fed's commentary on the horizon, the promise of continued stimulus could be enough to push bond prices higher.
