Is there any reason for the fall in high yielding dividend counters?

I know a lot of folks are fans of high yielding stocks (high dividends stocks) and are heavily vested in it. If you have notice recently, a lot of these high yields are falling like flies.
What happens in such a situation? the yield gets more attractive. some good examples are MIIF, Allco REIT, Cambridge REIT, Babcock & Brown.

So do they make a good buy now?
I’m still investigating the repercussions of the sub prime mess and credit squeeze and their effect to these counters.
Personally for me to be vested, I would really need a bloody large yield to make me feel safe. Even then, it might not be enough.

Considerations:
Inflationary environment will make holding high yielding counters very risky. If the rate of inflation truly picks up, even if you are holding a counter yielding 6% it will still be badly affected if the short term rates hovers around 4% and upwards. Investors would demand higher yields to hold such counters. If they are unable to do this through yield accreted business moves, their share price must fall to compensate to achieve the market demand yield.

Competition between securities:
this has slipped my mind but a post in channelnewsasia alert me to such a possibility:

In my opinion if someone holds BBSFF from IPO until now, the person would have made a loss on his position including all the dividend. If someone buy the counter during its rally to $1.22, he or she would have lost more. Only if you buy at the low of $0.80plus then you are still green…

The more fundamental question is why the price is dropping if the yield is very attractive. I believe all the high yielding stocks was affected by the credit crunch due to the sub prime loss.

Why? Major players such as funds, financial institution such as banks have to liquidate their holdings of global stocks to raise cash. This caused the price of such stocks to drop substantially.

Few months ago, investors are not asking for high returns on their investment such as convertible bonds. In fact a lot of M&A activity was done cheaply. Look at the present situation…UBS are paying 9% to GIC per annual for their investment. Morgan Stanley is paying the same to China fund. Citigroup is paying 11% to their Middle-East investor. This shows that investors are asking for much higher yield in the current market.

Let me post a question for thoughts…If you are a institutional investor, would you lend your money to UBS or Morgan Stanley at 9% or buy BBSFF at much higher yield?
I am not trying to talk down the share price of BBSFF but i just want to explain the logic why the high yield of BBSSF is not able to support the share price.

So the lesson learn is not to buy because the yield is good.
Always ponder about:
1. Free Cash flow strength
2. Business model in future and current economic climate
3. Ability to improve cash flow
4. Profits Margin
