As I noted in an earlier post (See Asset Class Returns for 2009), Canadian REITs were red-hot last year, posting a total return of 55.3%. While REITs are still roughly 25% off their all-time highs, several valuation metrics suggest that they may not be big bargains any more.

Take the distribution yield, for instance. The cash yield on the iShares CDN REIT Sector ETF (TSX: XRE) is approximately 5.45%, a spread of less than 2% over the 10-year Government of Canada bond, which is currently yielding 3.55%. Historically, the REITs have yielded as low as 0.73% over bonds and as high as 10%, suggesting that current yields are at the low end of the range.

Many REITs are also trading at a premium to analyst estimate of net asset value (NAV). RioCan (TSX: REI.UN), the largest REIT in Canada, for instance, is trading at $19.90 but TD Securities analysts estimate the NAV per unit to be just $16.30. RioCan’s current 22% premium to NAV is also in the higher end of its historical range suggesting that Canadian REITs may not be screaming bargains any more.
