The PPS from a R/S is just not as simple as a strait forward mathematical conversion
The question is do investors truly see them as a $6 stock as it currently stands. We currently have $6-7 biotech companies that have a lot more going on and yet they are still $6-7 . I am not sure that ZLCS is going to hold $6 in the short term until they have results as backing. This would ensure a more relative PPS
True story: I had a stock called eConnect; it dropped and settled at 2 cents. They did a 100:1 reverse split to make it $2. A month later it had dropped and settled back at 2 cents. Perception always beats math.
The price of the stock only has some relevance because I stitutional buyers put a dollar per share limit that they will not buy below. Asking whether it is a $6 stock is completely meaningless. It is all about market cap. Others have tried to explain that to you. If you don't understand that then I agree with other posters - you should not be investing yourself. This company has a smaller key cap. Period. If Z-160 works, the company will be perceived to be way undervalued - based on market cap, not share price.
That depends on whether you feel the company is going to double or triple in stock value because of a catalyst. If a stock has 1 million shares and is valued at 100 million dollars, your stock price is $100 dollars a share. If a stock has 1 billion shares and is valued at 100 million dollars, you have 10 cents a share. If the company comes out with a pill that makes it worth 100 million more dollars, your stock will only go up 10 cents on the billion shares or 10 dollars on the million shares. So you can own 1,000 shares at $200 = 200,000 or own 100,000 shares at 20 cents = 200,000. Either way you look at it, you have the same value. Why would people ever buy Apple if they didn't think the stock would give them some sort of return whether its dividends or increase in stock price.
