Average PE ratio multiple is 36 for companies in the medical instruments market. And the range is from 0 to 126.
TMO ( Thermo Fisher Scientific) PE ratio is 32. In 2018 they had revenue of $24B and profit of $11B.
Example 1: If Arrayit has $100M in revenue and $10M earnings (profit). and you use the 36X average multiplier the market cap could be $360M or 0.32 per share.
Example 2: If Arrayit has $100M in revenue and $50M earnings (profit). and you use the 36X average multiplier the market cap could be $1.8B or $1.6 per share.
Mark likes to use 100X multipler for his projections.
We don't know what the revenues or earnings are, so any calculation would be pure speculation.
