Mortgage rates are climbing out of the gutter, and some evidence shows the bargain-basement buyers who drove part of the housing rally are drying up, writes MoneyShow's Jim Jubak, also of Jubak's Picks.

Housing prices rose in March at a 10.9% annual rate, according to data from the Case-Shiller Index reported yesterday. But shares of homebuilders took it in the neck.

Toll Brothers (TOL) plunged 5.22% and DR Horton (DHI) was down 4.55% for the day. Lennar (LEN) fell 4.38% and KB Homes (KBH) dropped 2.94%. Only Pulte Group (PHM) managed to score a tiny gain of 0.26%.

Why the drop on good news? Because there was bad news that, for now at least, trumped the good news.

In May, the average interest rate on a 30-year fixed mortgage backed by the Federal Housing Administration climbed to 3.59% from 3.35%, according to Freddie Mac. The average rate on a 30-year fixed-rate mortgage with confirming loan balances increased to 3.9%, the highest rate since May 2012. The average rate on a jumbo loan increased to 4.07%.

The fear, of course, is that higher mortgage rates will translate into fewer home sales. From the perspective of those fears, the good news is backward-looking and the bad news is forward-looking.

And before you offhandedly dismiss those fears, please note that the total number of mortgage applications fell by 9% last week from the prior week. Refinance applications fell for a third consecutive week, the Mortgage Bankers Association reported.

If you're looking for sectors exposed to rising mortgage rates, don't stop with homebuilders. Financial companies specializing in mortgage-backed securities have also been taking a beating, as rising yields on this paper drive down prices.

For example, a tranche of mortgage-backed securities that traded at $107 at its peak closed yesterday at $104. That has taken down the stocks of companies such as Annaly Capital Management (NLY) and American Capital Agency (AGNC).

Annaly fell 3.47% today. American Capital Agency dropped a much smaller 0.04% today, but that's quite probably because American Capital is already down 20.7% from its April 30 close.
