Time for a practical example I think.
Biotech companies have extremely long lead times to go from idea or concept in a lab to a product on shelf. Takes decades, and whilst a biotech is developing it will burn cash on clinical trials and other expenses. So most of these types of companies have negative cash flow. Most analysts therefore base their recommendation on a discounted cash flow model. X amount of time till product on shelf, x amount of sales in the first year, x amount of license fees, discounted back to present value. Simple eh? Of course during a financial crisis......they have no earnings and they are burning cash. So when times are good they can go well, when times are bad they can stink to high heaven.

and look at the research released by ABN Amro on the stock on the 14th of May 09. Then go look at the research in May 07.
In two years the recommendation went from
Buy with a $1.42 target price
to
Buy with a $0.19 cent target price.
Yet both of these models are built on a discounted cash flow methods. Subjective as hell eh? Did you find that a useful guide?
Now if the stock hit's 19 cents, does that mean we should jump like a rabid lemming? Depends on what you think of the stock. If you think that the number of people infected with HIV will increase, that Avexa's research and product has a low side effect profile and is likely to be granted by the FDA once clinical trials are completed and then they will be pulling massive amounts of cash in the future with extremely high cost mark-up and perfect intellectual property protection..... they you might want to consider it a longer term hold.
If you think it's a cash sucking dog in your portfolio and they keep raising funds that constantly dilutes the company value and you want to treat it as a trading position....then you
might use that 19 cents as a guide to exit your position.
Clear as glass?
P.S. this is in no way a recommendation for the company AVX. Do not make me bring out the disclaimers. This is clearly an example.
