I have been considering alternate approaches.

Some years ago, I bought AMLN. It proved profitable and
their drug is truly lifesaving. I know individuals who
have benefited from Byetta.

At this time,my "largest share holding" demonstrates a similar potential.
Phase 1 and 2 tests are extremely promising.
There is a high probability it will trade in a manner similar to DNDN.

DNDN, unlike many penny stocks, has retained its value.

I am comfortable with this approach.
