You misunderstand the important difference between the two companies. NLS was underpriced at $12, and 3M is overpriced at $80. So NLS was a good investment and 3M is probably a poor investment. At the price. That's the difference between the two companies.
At 24, NLS looks like a pretty shaky investment too.
You shorted NLS around 13. You lost money. Doesn't that make you wonder whether you really understand what's going on?
